​Lai BuYi 賴布衣 SanHe Sect 賴公三合派 also known as SanHe Heavenly Star School 三合天星派 is an integral part of the New Method 新法. Lai BuYi claimed to have written, a difficult book, Urging Officer Scroll 《催官篇》. It contained techniques known as Embrace Leaning Star Method 撥砂挨星法: -
 
1.       Leaning Star 挨星法 is to Establish Facing to Receive Water 立向收水.
2.       It is also called, eliminate embrace to acquire water 消砂納水.
3.       Or simply Recline Mountain and Push Killing 收山出煞.
 
Many different jargons same story. This Leaning Star is called – Assistant Star Water Method 輔星水法. 

​The operative word – Assistant Star 輔星, self-explanatory is rooted in Changing Yao 飛爻, starts from the Assistant Stars – FuBi 輔弼, ends with WenQu 文曲. These 8 stars will determined the auspiciousness of incoming and outgoing water. Offspring of Assistant Star Method 輔星水法 are Five Ghost Carry Wealth 五鬼運財. This technique is mentioned in Entering Earth Eye 《入地眼》. This work was believed to predate all other YangGong technique. The Human Plate 人盤 and the Heaven Plate 天盤 have not been invented. Assuming. Lai BuYi borrowed this method, the use of Human Plate 人盤 to measure will not get consistent results. Assuming this Entering Earth Eye has been bastardized and somehow Assistant Star Method managed to creep into its pages, shouldn’t the Heaven Plate 天盤 be used to audit water? Blatantly, Entering Earth Eye state that Heaven Plate 天盤 is full of crap, years before Lai BuYi was born! Furthermore, what about Assistant Star’s long lost cousin, Huang ShiGong 3 Nobles 6 Auspicious 黄石公三吉六秀? Simultaneous application or standalone? 

​The predecessor to Assistant Star Method is believed to come from the 24 Heavenly Stars Method 廿四天星法. 24 Heavenly Stars were derived from the ZiWei enclosure. These stars represent the Imperial Court such as Heavenly King 天皇, representing the Monarch. It was said that the Hai Dragon 亥龍 produces Emperor. Hai 亥 is associated with Heavenly King 天皇 star. The other nobles are: -
 
1.       Great Subtlety天贲,
2.       Heavenly Market 天市,
3.       Great Yi 太乙 and
4.       Lesser Subtlety 少微.
 
These collectively made up the 3 Nobles 6 Auspicious 三吉六秀 where the 6 Auspicious were derived from 24 Obscure Heavenly Stars NaJia 廿四渾天星纳甲. To those school who subscribed that Entering Earth Eye 《入地眼》 predates Urging Officer Scroll, they will annex these 24 Heavenly Stars to the Earth Plate 地盤, while LaiGong School 賴公派 will annex these 24 Stars to the Human Plate 人盤 , to derive YinYang. This method became the qualifier to Assistant Star Method and 3 Nobles 6 Auspicious三吉六秀.

​Assistant Star Method 輔星水法 and 3 Nobles 6 Auspicious三吉六秀 measure the dynamic. The Human Plate 人盤, invention of Lai BuYi, measures the static. Static and dynamic are the manifestation of Formula versus Landform as the saying goes 巒頭無假理氣無真. Within Human Plate 人盤, its YinYang were derived from the 24 Heavenly Stars while its element is derived from the 28 asterism 廿八天星.
 
24 Heavenly Stars 廿四天星 differed from 28 asterism 廿八天星. 24 Heavenly Stars are star groups within the ZiWei enclosure while 28 asterism are star groups within the equatorial belt. It is this 28 asterism 廿八天星 that defined the static elements of the Human Plate 人盤. Human Plate’s 24 mountains were divided into 6 groups: –
 
1.       4 Yang Stems,
2.       4 Yin Stems,
3.       4 Ordinal Gua,
4.       4 Stables,
5.       4 Growths and
6.       4 Graves.
 
Mountains within the same group shares the same element, which correspond exactly to the 28 asterism.
Human Plate 人盤 is used to: -
 
1.       Evaluate the quality of the embrace 砂
2.       Ascertain that the embrace protects the meridian.
 
It is not a water method 水法 but an embrace method 砂法.
All the peaks within the embrace 砂 shall collectively produce 生 or prosper 旺 the Xue in the 5 elemental五行生克 interplays.

​Zhang JiuYi 張九儀 (1660 – 1730) studied under Jiao RenShan 焦仁山, disciple to Lai BuYi 賴布衣. He is believed to be the torch bearer for LaiGong’s lineage. From his writing, Earth Study Alchemical Towrope《地理鉛彈子》, it is learnt that one undisclosed secret technique called – Central & Fire Two Star Methodology 中火二星法, is the key to ignite LaiGong’s method.
 
As a rule of thumb, this technique require one to: -
 
1.       Employ the Heavenly Ruler 量天尺, simply means measuring the 28 asterism 廿八天星.
2.       There is a full fledge art of doing this - Seven Governors and the Four Remainders 七政四餘.
3.       Narrow down and to locate the positions of the Central Star 中星 and the Fire Star 火星 (see table).
4.       To establish the 4 Auspicious and the 3 Nobles 四吉三奇 within.
5.       4 Auspicious 3 Nobles 四吉三奇 are Yi乙, Bing丙, Ding丁, 3 Nobles 三奇.
6.       Locate the Salaried Horse Nobleman Method 祿馬貴人法 within.
 
It is really Rocket Science in Lai BuYi’s time. In Urging Officer it states, Fiery Star 火星 not rise Officer 官 not prominent 火星不起官不顯. In Zhang’s writing, it states, without the Central Star, nobility will not see 無中不發富, without the Fire Star, ignition will not take place 無火不開科. Can you believed it? We must take this with a huge pinch of salt…

The 24 Heavenly Star methodology 廿四天星法 forms the Body 體 or the Principle. To some it is a way to locate the Meridian Spot – LaiGong Dotting the Meridian Technique 賴公點穴法. Others believed that it is how based on the precedents of the Royal Imperial Tombs’ FengShui, these proved the quality of the TangLang 贪狼, JuMen 巨门, WenQu 文曲, WuQu 武曲 and FuBi 輔弼 stars are auspicious perpetually as it corresponds to the Great Subtlety 天贲, Heavenly Market 天市, Great Yi 太乙, Lesser Subtlety 少微, Heavenly Monarch 天皇 and the Purple Enclosure 紫微. Collectively, they are named – Mother Earth Flipping Trigram Nine Star Plate 地母反卦九星盤, where Kun trigram is the Host. That is also where GuiChang 归藏 was to be arranged…

Mother Earth Flipping Trigram Nine Star Technique 地母反卦九星法 was later enlarged to cover what is now known as 3 Auspicious 6 Elegance 三吉六秀 as Mountain Method 山法 and Assistant Star 輔星 as Water Method 水法. Both methodologies form the Application 用. When one uses the Mountain Method 山法, one is able to simultaneously narrow down to the specific 60D Penetrating Dragon 穿山龍 GuiChang Gua 归藏卦. When one uses the Water Method 水法, one is able to simultaneously narrow down to the specific 60D Penetrating Dragon 穿山龍 Obscure Heaven Gua 渾天卦.

Human Plate Embrace Method 人盤中針撥砂法 is a static application to evaluate the quality of the embrace 砂 protecting the Meridian 穴.  When one uses the Embrace Method 砂法, one is able to simultaneously narrow down to the specific 60D Penetrating Dragon 穿山龍 LianShan Gua 连山卦, by measuring the embraces’ peaks. All the 3 sets of Gua 三般卦 derived from the 3 sets of   60D Penetrating Dragon 穿山龍 GuiChang 归藏, Obscure Heaven 渾天 and LianShan 连山 Gua would enable a detailed readings of: -

1. Salaried Horse Noblemen 祿馬貴
2. 3 Mysterious and 6 Auspicious三奇四吉

Having said so, there is a much reserved techniques called the Central and Fire Two Stars Methodology 中火二星法. It is where you need to determine the arrival of the Central 中星 and Fire Stars 火星 respectively. These require a little bit of acrobatics with astronomy as both stars are in reference to the Pole Star 紫微 (To locate the Pole Star read HERE) and the planet Mars 火星, to enable specific date selections so as to allow for immediate FengShui outcome.
​
To eliminate Killing Qi or ShaQi 殺氣, the techniques of Great Sun and Great Moon formulas 太陽太陰到山 are prescribed as the saying goes, when the Great Sun and Great Moon 太陽太陰到山 arrived at the particular mountain, all malignant Qi will be dissolved. This will enable one to determine your seating… not just the greatly misunderstood basic date selection techniques.

​There are 2 sets of 28 asterism rings currently found in most modern LuoPan: -

1. The Old – Epoch is set in the beginning of Sung Dynasty  宋朝  960, known as KaiXi 開禧 epoch.
2. The New – Epoch is set in the beginning of Qing Dynasty 清朝 1644, known as ShiXian 時憲 epoch.

By 2008 (another JiaZi cycle) it would have lapsed 364 years. By virtue of YuXi 虞喜 calculation (being the first Chinese astronomer who observed the Precession of the Equinoxes), suggested that for every 70+ years the precession of the equinoxes ShuiCha 歲差 would rendered the asterisms to be deviated by 1 degree and with such 364 years, that will make up a total of 5.2 degree deviations. 

LaiGong 賴公 uses the Old Epoch. By this time, due to precession of the earth, the current degree of the 28 asterism 廿八天星 would have been out of sync by 15 degree (that is One Mountain). By the same token, it means to say these techniques of LaiGong 賴公 would have been stale. Some practitioners warrant that the current degree of the 28 asterism 廿八天星 would have to be updated every 70 years – most likely you only need to do once every life time and to re-engineered the entire techniques to keep them applicable.

One School suggested that you may need to read the New Epoch and to traced back to the Old Epoch when validating old graves based on LaiGong's methodology.

What a daunting task…

One FengShui connoisseur from Vietnam shared a murder case as his basis of XuanKong analysis based on the school of WuChang Pai 無常派. With unfortunate cases like this, it is highly unlikely to do a prediction based on whatever LoShu chart we have. The most we could only do a post-diction, see if it does correspond to the numbers in the LoShu chart, the WuChang 無常 way… 

According to the treatise of WuChang Pai 無常派, a sudden death event occurred in a family is highlighted via what is probably known as FuYin 伏吟 and FanYin 反吟 within the LoShu chart. Yin 吟 is siren, ought to have sounded in giving a life and death warning to the inhabitants.

FuYin can be understood as Repeated Siren, it is liken to someone repeating the same warning to you again and again in an annoying manner and it is considered to be greatly inauspicious. That happens when the mountain or facing star in the middle is the 5 Yellow. The numbers may repeat the flying pattern of the LuoShu numbers in any palace.

FanYin 反吟 is short for Fan FuYin 反伏吟 or Opposite to Repeated Siren. Some teacher takes this as auspicious because it is supposed to be the reverse of FuYin. However, it is truly inauspicious because in any palace the numbers (Mountain or Facing number with the Luoshu number) added up to 10 and this happens when the Mountain or Facing star in the middle is the 5 Yellow. Beyond a superficial level, you will also see that it don’t make sense at all, as a combination of 10 should always be beneficial, but why not for this instances? What is the catch? The caveat is in this term - Fan FuYin 反伏吟 whereby when a FuYin occurred, it may also come together with its reversal, thus its double whammy. It doesn’t really make sense in terms of the stars but it truly make sense in terms of DaGua.
​
FuYin 伏吟 and FanYin 反吟 usually denotes deathly events and if the structure is not timely or broken and does in any manner conform to the natal chart, its malignant effects are great. In many books on this subject, the most fear after FuYin 伏吟 and FanYin 反吟 is the facing, because the Qi mouth of a house is usually located at the facing. However, as the saying goes, water governs wealth, mountain governs health, it cannot deny that an occurrence of FuYin 伏吟 or FanYin 反吟 at the sitting instead of facing, gives the more detrimental effects to the inhabitants in terms of health matter.   

A murder case, happened in North Vietnam at early morning 24th September 2016. The house was built and moved-in in 2015. The house measured sitting Yin facing Shen - 243 degrees. 
Upon moving in: -

1. The eldest son was killed in an accident in same year 2015.
2. At an early morning 24 September 2016, the grandmother and 3 grandchildren were murdered by an unknown killer.

​Googlemaps revealed that the location is far from superior as it is located within the basin known in geography as the island of the ox-bow. Landform liked this has very little Qi, thus a broken structure. Its location having rivers at both sides, with the rear river closest indicating the front may have been higher with the back low. In XuanKong 4 structures this is known as backward riding the dragon or up the mountain down the water structure, where the sitting star may not be that strong after all.

The house was built and moved-in period 8. A period 8 chart with sitting Yin and facing Shen is constructed. The facing palace comprises of the period star 5, facing star 2# and sitting star 8#. 2#-8# combination 10 at facing. Wouldn’t such be great? Unfortunately, this natal chart of the house also called, arranging the dragon 排龍 of the house has nothing to reveal as it has no FuYin. Better still, sitting star 8# that is timely meeting facing star 2# that is untimely will violate the entire benevolent of the timely star? Mind boggling… Perhaps, the sitting timely star 8# arriving at the facing violate the cardinal rule that the “mountain dragon god shall not go down the river, 山上龍神不下水，水里龍神不上山, 青囊序，Mountain on top Dragon God don’t come down to water, Water within Dragon God don’t go up the mountain, (QingNan Xu). Therefore, the timely 8# sitting star has been violated and rendered useless…

When we plot in the annual 2016 star - #2 arriving at the centre, appear before us is a FuYin 伏吟 chart. The annual star and sitting star are in FuYin 伏吟 formation for all the 9 palaces. We shall check if indeed it is a FuYin 伏吟 formation at the facing.
​
There is a second test to see if indeed it is a real FanYin 反吟. This is through AiXing 挨星. Facing has 8#-8# Gen WeiShan 艮为山 Gua.  Based on Gen WeiShan 艮为山 Gua, we have Dui WeiZe Gua 兑为泽 Gua as its FanYin Gua and Zhen WeiLei Gua  震为雷 as its FuYin Gua. Given house measured sitting Yin facing Shen - 243 degrees, none of the AiXing 挨星 falls within the FanYin nor FuYin. Yet, there are people killed! The above said description failed the litmus test… miserably. 

Perhaps, we may look at the individual room itself before we come to any conclusion…

1. The kitchen – 3 casualties.
2. The Masterbed room – 1 casualty.

If we were to assign the natal chart into the house according to what is perceived to be the right  WuChang Pai 無常派 approach, we ends up having the followings: -

1. The kitchen - period star 4, facing star 1# and sitting star 7#. 7#, untimely therefore bloodshed and #1 surpassingly the future prosperous star has no effect to nullified the 7#. Honestly, I don’t buy this postulation. FuYin 7#-7#, sitting with the annual star. Dui Gua – FanYin Gen Gua, FuYin Xun Gua. As Xun AiXing Gua falls within the Kun palaces comprising the Shen facing mountain, it foretell a real FuYin.
2. The Masterbed room - period star 1, facing star 7# and sitting star 4#. 7#, untimely therefore bloodshed and #4 also untimely… Honestly, I don’t buy this postulation also. FuYin 4#-4#, sitting with the annual star. Xun Gua – FanYin Zhen Gua, FuYin Dui Gua. As Dui AiXing Gua falls within the Gen palaces comprising the Yin sitting mountain, it foretell a real FuYin.

From this one room, one TaiJi perspective, it conforms to real FuYin and the post-diction results are casualties happened to both the Kitchen and the Masterbed room. It consistently fulfilled the litmus test. Yet, one question remain - is this really coincidence or otherwise? 

​The house measured sitting Yin facing Shen - 243 degrees are very close to a small DE under the 72D rings based on YangGong methodology. It already foretell issues related to bloodshed. A good theory, must consistently without failed proved to show result even by the method of reverse engineering. In this instances, it has showcased that FanFu Yin can only be applied to one room, one TaiJi applications. Beyond that it seems that the theory faulted in many areas. This is only one attempt based on a popular known so called WuChang Pai 無常派 applications. How about the rest of the XuanKong derivatives such as MiaoPai 妙派 and so forth? 

As its name suggested, it comprises of 6 factors of XuanKong. Some says, XuanKong LiuFa or also known as XuanKong 6 Methodologies was once a mysterious FengShui system that was strongly advocated by the late Grandmaster Tan YangWu (淡養吾). In 1929, Tan met a Daoist by the name of Li QianXu (李虔虛道長), who later imparted XuanKong LiuFa to him. Another theory state that XuanKong LiuFa is the genuine transmission by the founder Wu JingLuan and It has a shroud of mysticism around it because those who know it do not share the method openly and claim that it is the only true XuanKong teaching and knowledge. Moreover they tend to use strange words and terminology which nobody seem to understand unless you have some foundation knowledge on the subject. XKLF consists of 6 key components - that is why it is called 6 Methods. Actually the translation is a bit misleading because they are not individual methods by its own but key concepts or principles that need to be applied in a holistic way in order to realize its full FengShui potential. The 6 methods of XKLF are: 

XKLF’s fundamentals are from the YiJing and it places the importance to the concept of Taiji. Unlike XuanKong FeiXing XKFX school that emphasized one room as one TaiJi, meaning there must be within an enclosure, XKLF TaiJi stems from the very human as a reference point against the Qi mouth, be it incoming Qi or outgoing Qi. XKLF believes that human is always concerned about the effects of FengShui. Therefore it places human as the centre point of focus. For building, TaiJi is established at the centre of the building. XKLF considers the bed, workplace as the central datum to establish its TaiJi to take measurements, in addition to placing the TaiJi on the building or the rooms. It gives great flexibility in tapping into the Qi map at any given place by just tilting the desk, bed and so forth. On a larger scale, with the same set of TaiJi and the Early Heaven BaGua one is able to determine the luck of the building based on its facing direction in relation to the nearest Qi mouths such as junctions and road intersections. It is an absolute versatile tool to employ from all types of building to push cart hawker stalls.
​
XKLF uses the 2 Yuan 8 Yun or 2 Cycles and 8 Period instead of the 3 Cycles 9 Period of XKFX. The period 1, 2, 3 and 4 belongs to Upper Yuan while Period 6, 7, 8, 9 belongs to the Lower Yuan. There is no Period 5. The length of each is not fixed like XKFX but it varies according to the Yao of the Gua it represents. A Yin Yao represents 6 years while a Yang Yao represents 9 years. For our current period, it is period 8 starting from 1996 lasting for 21 years. Period 9 begins in 2017.

The fundamental theories on this method is derived from QingNan Xu ​青囊序.

​It is about the interaction and union of the male Qian and female Kun, as represented by Yin and Yang, producing offspring of different gender. Without male, female cannot produce. Without female, male cannot grow. Therefore there is always inter-dependency between the male and female and the need for each other to coexist. One cannot survive without the other. Unlike the notion of XuanKong 玄空 which is non-physical, CiXiong 雌雄 is physical manifestation of Male and Female. This concept is extended to Water vs Mountain, Moving vs Stillness, Building vs Road Junctions, Heavy Furniture vs Doorways, etc. The origin of this principle stems from the Early Heaven BaGua where any two opposite Trigrams are always opposite and complementary to each other. Such became its basis to analyse land form.  Unlike XKFX, it requires the water mouth as a central reference point for its analysis.

​These stars are the 9 stars of the Great Dipper. They are: -

​These 9 stars are mapped to the 9 LuoShu numbers based on the trigram it is associated with.
​
Unlike XKFX that uses the concept of Flying Star within the LoShu, XKLF uses the concept of Leaning Star that means the star lean one against another based on the principle of flipping Yao to change the Gua Imagery 抽爻換象. Unlike XKFX that uses the 45 degree influence of an entire Gua, XKLF uses the 15 degree influence of an entire mountain itself. A trigram is assigned to each of the 24 mountains with a Leaning Star associated to each mountain. When the flipping Yao to change the Gua Imagery 抽爻換象 sets in, an addition of 8 trigrams are produced and these are positioned to the 24 mountains with an additional 2 trigrams attached to these 8 mountains. Altogether it becomes 32 mountains instead. For each period, the configuration of the 32 mountains differ. 

The core theories of this method vested in Parent SanBan Gua as in TianYu Jing ​天玉经.

XKLF practitioners are very good a seizing up the fortune of a house or a place fast and accurately based on a predictive method called TaiSui that uses extensively the stems and branches combinations just liked its BaZi counterparts – 3 combo, clashes, penalty and destruction. XKFX will use the annual purple white stars with its daily and monthly stars through its 81 combinations to foretell the fate of a building, XKLF uses mainly the TaiSui replacement method of stems and branches. Besides prediction, XKLF also uses this method for date selections and activation.

Castle Gate is almost the same as Receiving Yin Pushing Sha Script 收山出煞訣 of the Zhong ZhouPai or the Eliminating Embrace Receiving Water 消砂纳水 of the GuFa Pai 古法派, if it is not the form at the entirety but the essence may be of the same. Cheng Men or Castle Gate is classified as the topmost secret among the 6 methods. It is only taught to the most trusted students. The simple reason is that it is the application of the entire XKLF curriculum. You can master the other 5 techniques but without this Castle Gate, you don’t know how to apply XKLF.

It can be construed as a simple technique to position the door or house facing/sitting based on the incoming mountain dragon and outgoing water. Unlike XKFX that require one to know the move in date and sitting/facing of the property, XKLF required the location of the water mouth. This technique is quite similar to the XKDG or the 5GCT formulas that is closed to Dragon, Mountain, Facing and Water structure thus the 2 parts to this formula, Mountain Dragon Castle Gate and Water Dragon Castle Gate. Put it bluntly, the incoming and the outgoing Castle Gate. Kindly also aware that this XKLF Castle Gate has nothing to do with XKFX Castle Gate that tap into the 45 degree auspicious star sector based on HeTu connection.

The key principle of Incoming Castle Gate is the HeTu. Very similar to QKGB or LMBDJ methodology the sitting trigram and the incoming dragon trigram must form a HeTu combination in order to be considered auspicious. Facing is the opposite of sitting. By applying this technique, you can match door location to the incoming dragon.
​
The key principle of Outgoing water Castle Gate vested in the Incoming Dragon trigram in Early Heaven sequence and the door facing trigram in Later Heaven sequence must be the same. It is simply a matter of matching correctly the Early Heaven and Later Heaven trigrams between the door facing and incoming dragon to put the structure in order.

You will require to master this modus operandi to design tombstone and house facing based on the core principle of  "A Thousand Buddha" Character Script 万佛字诀 vested in QingNan AoYou 青囊奥语, unlike XKFX that only can be applied to Yang House FengShui prediction.

If you were to take 2 practitioners for a field trip, one being a XKFX junkies while the other a XKLF junkies you would find that the XKFX fellow will be totally lost in transition trying to figure out the stars running across a piece of paper with 9 grids and thereafter trying to talk his way through house divination based on the 81 stars combination with total disregard of the environment. XKLF practitioners on the other hand would be versatile in screening the entire formation to not only predict the outcome of a given structure but to also suggest the proper locations of the Main Door and the Tombstone to best tap into the most current auspicious Qi, all without the need to even draw the 9 grids and to fly the stars. They are among the closest and the best XuanKong methods available in the market today.

​YUAN KONG
Three Affinity Obtaining Void and Emptiness (SanYuan De KongMang) is YuanKong. WuJi born TaiJi, TaiJi obtain 2 slices, 2 slices beget 4 images, 4 images formulate 8 Gua, 8 Gua separate to 64 Gua, 64 Gua flip 384 Yao, the birth of a myriad things come from the great Void, WuJi. This is YuanKong. Think again, we were so afraid of the so called Death and Emptiness (DE). However, where is mother of all nature if it is not from Emptiness? If it is from here the myriad things are born, it is of here that the myriad things should return. This is the true reflection on Death and Emptiness. It is said that DE should not sit and face. True enough. The Qi is too pure and some extend may be too strong. Why would it said that way? If one mastered the use of the 6 Jia, DE is insignificant. SanYuan is the affinity of Heaven Earth and Man in obtaining another SanYuan of Health, Wealth and Family. This is the purpose of the Great SanYuan, fundamental of all human endeavors beneath Heaven. This is not the art of the gods, but an art of the mundane human being. Wars are fought, based on this reason. Empires are built based on this reason. Longevity is also gain on this reason. Heaven has 9 stars, Earth has 8 Gua and Human has 8 doors. Know how to use this, SanYuan is obtained. Combining the art of SanYuan, with the understanding of void and emptiness, this is YuanKong.
 
CIXIONG
Intercourses of the Yin essence with the Yang essence. Failure of comprehending Early Heaven as principle, Later Heaven as application, CiXiong will not materialize. When it is said, pure Yin, pure Yang, would one assume, how would Growing Qi be born when the Yin remains Yin and Yang remains Yang? This is the modern misconception. Whereas, what is use of Qi if it wasn’t pure? The Yin Yang dragons of the 24 mountain plate arraying the SanHe and SanYuan Luopan are varied based on what? When was it said, the mountain is Yang, water is Yin? Finally, who said the mountain is Yin and water is Yang? Not knowing this is not knowing CiXiong and not knowing CiXiong is not knowing how to use the 24 mountains. What is use of the Luopan then, be it SanHe or SanYuan?
 
AIXING
If we equate Leaning Star as AiXing, we are taking a tree instead of a forest. The principle of AiXing is the map? The application is the book? How naïve this could be? Master of the old said, arrange the 6 Jia and move the 9 dragons. What does this mean? If one fails to understand the meaning of RuGong PaiLong or entering palace, arranging dragon, save it, be it 24 mountain or 32 mountains, these are all Fei! Worst, if the debate is centralize in defining sitting star versus mountain star and water star versus facing star, absolute rubbish in discourse!
 
JINLONG
From where it comes, to where it goes, this is the golden dragon. The root verse comes from the following script of Qing Ran AoYou: - “…Dian dian dao, 24 Mountains have Treasure;Dao dao dian, 24 Mountains have Fire Pit.The Golden Dragon, Longitude and Latitude even though come with different meaning, Does it move or does it not move, all depend on the Master of Fengshui to apply…” First, one has to understand what is this dragon is all about? Why is it golden? Is it because the script is talking about Qian, being metal and being the head of the dragon? When we said a missing sector in Qian palace, does it also means to say the star AIXING would not takes it LoShu flight path and all that is to say about flying star FeiXing, would not work? Absolute rubbish! What does longitude and latitude mean? The book and the map, woven in longitude and latitude? Before it goes beyond paranoia, it simply says the use of the LuoPan to measures the 6 Jia. Knowing the 6 Jia is grossly insufficient, knowing how to use it is the treasure. Does it mean the Ling and Zhen Shen? Think about it!
 
CHENGMEN
This is the best kept secret. The magical door that required the keyword – Open Sesame, to activate? Consider, if ShengQi needs to ride, where would it be ride? Heaven has 9 stars, Earth has 8 Gua and Human has 8 gates, where are these gates and what is his castle? Mountain as principle, water as application, how does one use it? Be it 6 Jia, 64 Gua or 384 Yao, not knowing the nature of the gates of Man, Castle Gate is just another mouse trap. Think again!
 
TAISUI
The ruling Qi for the year or the guardian deity of the year? One has to understand who the host is and who the guest is. What is to be replaced and how it is to be replaced. The governing of the 20 years cycle, 10 years cycle all determined the locations of the 8 doors, opening and closing of the 8 doors. Most importantly the luck of the mansion.
 
​In conclusion, this is just a scribble of fictions and facts called, YuanKong 6 and a half method, anyone interested to learn out there?

​A fellow FengShui practitioner from France brought to my attention an article about the saga between flying star FengShui and the LiuFa FengShui. I read with interest unto the so called facts that had been placed forward as argument for argument sake. In the first instance these facts are beyond validation, only disciple of a certain lineage or schools could verify. So, I place my bet with these 10 arguments in mind for hopes that it may throw some new light, if any, to whom ever who read this blog, intellectually or casually.
Originally there is only 1 school. It will be quite whimsical to classify a method as time based such as SanYuan or three periods simply because time is of the essence to such a methodology. In fact, SanHe, three harmonies, the so called oldies also has their own time dimension. It will be just a folly to say BaZhai as a SanYuan methodology. It could have been a SanHe school. So, the history of FengShui must first be re-written. There is no SanHe or SanYuan. There are many lineages and sub lineages, all to their very specific purpose and use. In fact, BaZhai could have read as a macro of XuanKong DaGua, so where is the disdain fallacy?

Flying Star is a relatively new method at most born out of writings from Tang Yang Wu and Shen Ju Ren. These masters may have quoted from the classics notably DiLiBianZhen to offer their views as in XuanKong BenYi and Shen Si XuanKong Xue, could these masters interpreted the classics correctly given the fact that they may not inherit the transmission from the proper lineage? Same goes with the LiuFa, where the emphasis is on the 6 method of Zhen and Ling Shen, CiXiong, Chen Men, TaiSui, AiXing and others. My question is why 6? Could have been more considerations?
Magnetic North versus True North controversy. The evolution of the Chinese compass was from the sundial having the 24 mountain plate created by YangGong. Those from YangGong traditions will immediately know that the Sun is the factor. Similarly in deciding the actual timing in hour’s selection for FengShui. Food for thought.

Rotation of earth moves in one direction. Rotation of Earth moves in one orbital direction. Time moves forward and never backward. How possible could a period, Yun, sometimes move forward and sometimes move backward in accordance to the Gua Yao of the particular period in question?

The YangGong GuFa lineage does not recognize Yi Long Jing and Han Long Jing as written by YangGong himself. So, how could we rationalized based on these 2 classics?

If bright hall should be big, then why is there a saying that to consume by the bright hall? Meaning to be drawn by the bright hall?

There is a big different between the Yin dwelling and a Yang dwelling. The Yin has 1 compartment, the Yang has many. Flying star 9 palaces cannot fly in 1 compartment. So how to deal with this?

Bright hall must have South Facing, meaning all South facing houses and graves must be prosperous and is that so in the practical sense?

3 elegance and 6 auspicious has many definitions. In terms of regulating water courses, there is no such a thing as many incoming but single outgoing. The notion of the incoming and outgoing water mouth must first be investigated.

The constellation or asterism inclusion unto the 24 mountain plate called the seam needle in the SanHe Luopan, sometime called human plate were based on astronomical considerations invented by Lai BuYi. The old school of YangGong does not use this ring, although to some extent Lai BuYi were known to have received YangGong’s transmission from his father whom had learnt the art from YangGong’s senior disciple. Lai BuYi improvises on the system to make it for his own. The XuanKong proponent further improvises on these and called it by different terms such as XuanKong Dawuxing. So, one do not necessary need a heavenly sign to do FengShui.

These points are not meant to debunk any fallacy nor a sales gimmick that may arise, but to intellectually provoke readers whom had happened to come across an article about the saga between LiuFa and Feixing. Perhaps one may drop me an email for me to direct them to the source article found in the WWW.

This is the last installation of the article on Death and Emptiness. It is related to the use of 120D. Very little has been written on this topic in the English language. First, an introduction into the nature of 120D.  Second, an explanation of what and why only the 4 stems are used in the 120D. What is the secret of Turtle Shell Emptiness and compressed Emptiness. If you care to investigate further these rings attributed to the concept of both NaYin and NaJia to justify the theory. Very unlikely it has to do with true YangGong method. Third, close scrutiny, it may also used as Central and Marginal reading for the Replacement techniques.  Fourth, its application, something that Master Hung admitted that it has taken him "donkey years" to figure out how the DE line is being used. If you understand these truly, you will read the Poem as attached in a totally different light! The translation of the Poem, taken from "the Old Fox" is totally OFF... Just too lazy to translate it again... Have Fun!

Let’s introduce the 2 rings of the SanHe LuoPan the "120 Dragons Gold Divisions, hereinafter called 12D. One, associated with the Earth Plate while the other, the Heaven Plate. Both are virtually identical except for a shift of 7.5°. The first plate is called the "Earth Plate 120 Dragons" EP120D. The other is called, “Heaven Plate 120 Dragons" HP120D. We use the EP120D first, and only resort to the HP120D if we don't get what we want from the EP120D.

Continue from HERE,  This marginal degree of 3° at each extreme side closer to the boundary of the two mountains that made up the 6° are considered by some SanYuan  FeiXing as Replacement Star band. Any star that reside thereafter must be replaced by the set of new stars as represented in the Replacement Star Ring. Some school of XuanKong Purple White do not subscribe to this principle. Some school also do not agree with the version of the Replacement Star Ring used, currently at 28 varieties. In the 120D, these 2 most extreme sides are not in used.

Each 120D is 3°, and contains a JiaZi, from JiaZi to GuiHai. In these 120D, only the ones containing the Stems – Bing, Ding, Xin and Geng are usable (no more than 48 usable). These are called Jewel Lines. The important plate is in fact the NaYin elements of the respective JiaZi.

The next question is why these Bing, Ding, Xin and Geng are usable? Again, it has to do with NaJia. Jia and Ren belongs to Qian. Yi and Gui belongs to Kun. Both Qian and Kun are solitary Yang and solitary Yin. Solitary gender will not produce offspring – therefore they will never produce ShengQi. This is called Turtle Shell Emptiness as it means Monks and Nuns.
Wu belongs to Kan, Ji belongs to Li. Both Kan and Li has Yin Yao and Yang Yao smacked in between. These compressed Yao has been overpowered and therefore will not produce offspring – therefore they will never produce ShengQi. This is called Compressed Emptiness.
​
The leftovers as Bing, Ding, Xin and Geng. Therefore they are usable. Some LuoPan only has these Bing, Ding, Xin and Geng marked in the 120D.

120D specify that there are only two – 3° sectors within a Mountain that are usable. Upon checking the NaYin of the selected 120D does not counter the NaYin of the person's Year Pillar for example RenZi – wood, Xun Sitting Mountain would be suitable for him. Within Xun, only the 120D BingChen and GengChen are usable. GengChen NaYin Metal. Metal clashes Wood, not suitable. BingChen NaYin Earth does not counter Wood — hence usable.

When a satisfactory 120D is unobtainable with the EP120D, we turn to the HP120D to find a replacement. This is also known as a Replacement Line as in Replacement Star.

Take the following example: a person's Year Pillar for example RenZi – wood. Qian facing Mountain is selected. Only permissible facing on the EP120D plate is BingXu. At the Heaven Plate of the LuoPan, the axis penetrates the Heaven Plate at Xu. Yang water flow would give Weakening, it is perfectly acceptable. What if water flow Yin? Such a facing would be inauspicious.
​
If 120D is GengXu, it conforms to Prosperous facing of water frame. Unfortunately, GengXu metal NaYin clashes with RenZi wood NaYin. The remedy is to put the EP120D into emptiness line, between GengXu and RenXu. Next, to line up with HP120D BingXu instead. Excellent solution! 

The response of Master Hung HinCheong to our post Leaning Star Oral Secret, he wrote, “You're right. That ring's pedigree is suspect. Some Flying Stars schools don't use Replacement Stars at all, and I think that's the smart thing to do.”, caused us to think further. We dug up some of Hung’s writing – Water, Water Everywhere and there is a nugget or two for us to share here…

Hung wrote…

In many FengShui texts, classical and modern, a given facing is differentiated into "Central 正向" or "Marginal 表向", and each is treated differently.

In modern mathematical language, a facing is described as "Central" if it lies within a band of -±4.5° from the center-line of a Mountain on the LuoPan. For example, the center-line of Zi (子) is 0°. Hence any facing between 355.5° and 4.5° is said to be facing "Central" Zi (正子向). Another example: Gui (癸) is centered on 15°; any facing between 10.5° and 19.5° is described as facing "Central" Gui (正癸向). The total bandwidth of a "Central" facing is therefore 9°. Any facing outside that band is deemed to be a "Marginal" facing. To be more precise: Zi (子) is centered on 0°, and Gui (癸) is centered on 15°. Any facing in between 4.5° and 10.5° is called "Marginal" between Zi and Gui (子兼癸，癸兼子). The total bandwidth of a "Marginal" facing is 6°.

That of course is the modern definition, making use of the 360° compass ring at the periphery of the LuoPan disc. However, this ring was a relatively recent addition to the LuoPan. Before that, the definition of "Marginal" relied on the "240 Dragons Gold Divisions (二百四＋龍分金)", and the term "3-7 Gold Divisions (三七分金)" was often quoted. Some readers may have come across this term in their general reading.

As a matter of fact, the 6° bandwidth for "Marginal" was set conservatively. It allowed a generous margin for error, mindful that the LuoPan needle and markings were not very accurate in the old days. My own view is that we need not be so uptight about the prescribed margins. The underlying idea is to get away from the boundary line between 2 Mountains, and our modern LuoPan enables us to do that with greater confidence.

Hung wrote…

In a typical SanHe LuoPan, there are the 72-Dragons ring (also called a plate), one or more 60-Dragons rings; and one or two 120-Dragons rings. There is one other ring in this genre that is omitted on LuoPan other than out-sized ones (12-inch and above). This is the 240-Dragons ring, also called "240-Dragons Gold Divisions (二百四＋龍分金). As the name suggests, the ring is sub-divided into 240 fine divisions, with 10 divisions under each of the 24 Mountains.

This ring is used to assess the intensity of qi received from a particular Mountain for any given facing. A Mountain's Qi is strongest at its center-line, gradually reducing to zero at the center-line of the adjacent Mountain on either side. At the boundary between 2 Mountains, the qi split is 50-50.

If a given facing receives 70% or more of the qi from one Mountain, it is called a "Central facing (正向)". If the facing receives less than 70% qi from one Mountain (say, a 60-40 or 50-50 split between 2 adjacent Mountains), it is called a "Marginal facing (表向)”.

Today, the demarcation between "Central" and "Marginal" can be defined using the 360° compass ring at the periphery of the modern LuoPan, but this ring was a relatively recent addition; it was not available in the older LuoPan.

So do we still have to bother with the 240-Dragons when we have the modern 360° ring? That depends: no need if we just want to use the LuoPan without bothering with the underlying theory; yes if we want to broaden our FengShui knowledge. If one reads old texts or spends time surfing the FengShui websites, then familiarity with the "240-Dragons Gold Divisions" will provide a deeper insight into various discussions.

To analyze the 240-Dragons ring, let us straighten out 2 arc segments, each segment spanning 30°. The first segment is centered on Zi (子) with Ren（壬） at one end and Gui (癸) at the 4 others. The second segment is centered on Gui (癸) with Zi (子) at one end and Chou (丑) at the other. The segments overlap, and the fine divisions are graded with a numerical value rising from 0 to 10 and then falling back to 0.

The dashed lines 7-3 and 3-7 demarcate between "Central" and "Marginal" facings. The region between those 2 lines, marked by a hatched box, represents the "Marginal" band between Zi (子) and Gui (癸) Mountains. There are similar "Marginal" bands between Ren（壬） and Zi (子); and between Gui (癸) and Chou (丑).

The scale in maroon at the bottom denotes the modern 360° compass, whereby the center of Zi (子) Mountain corresponds to 0° Magnetic North. The "Marginal" band between Zi (子) and Gui (癸) would correspond with 7.5±3° on this scale.

One often sees the term "3-7 Gold Divisions also called "Plus Minus 3-7 (三七分金)", in FengShui books and websites. It really means nothing more the demarcations described above. Some people like to use complicated language to describe simple ideas.

Sometimes the term "2-8 Gold Divisions (二八分金)" or "Plus Minus 2-8 (二八加減)" also appears, often in the same breath as "3-7". When one compares the Earth Plate with the Heaven Plate, it will be seen that "3-7" on the Earth Plate is in fact the same line as "2-8" on the Heaven Plate, and vice versa. They are really one and the same thing.
​
According to Master Li Ding Xin (李定信), who was until recently the reigning Doyen of Yang Gong FengShui [He passed away in 2012, age 90], many FengShui writers, historical and modern, are confused and use the terms haphazardly. So the next time someone comes along brandishing jargon terms like "Plus Minus 3-7" and "Plus Minus 2-8", just ask him about the "240-Dragons".

This marginal degree of 3° at each extreme side closer to the boundary of the two mountains that made up the 6° are considered by some SanYuan  FeiXing as Replacement Star band. Any star that reside thereafter must be replaced by the set of new stars as represented in the Replacement Star Ring. Some school of XuanKong Purple White do not subscribe to this principle. Some school also do not agree with the version of the Replacement Star Ring used, currently at 28 varieties. 

This Replacement Star Ring is interesting. In total you will get the following sequence from the opposite mountains combined: -

1. 1+9=10, combination 10, 4 pairs.
2. 2-7, HeTu Fire, 5 pairs.
3. 6-6, same Qi, 3 pairs.

​The question is could this Ring tells you something beyond just the greatly misunderstood Kun Ren Yi?

For example, House sitting Gui 23 degree, facing Ding, Period 8. By conventional  Natal chart, you will get as in A. However, because 23 degree sitting very close to Chou, a Replacement Star may be necessary. Based on the Replacement Star Ring, Sitting Gui replacement shall be 1 replacing 4. Facing Ding replacement shall be 9 replacing 3. The new Replacement Natal chart shall look like B.

Contemplate this, ​quote from BengKung's wisdom saying, "The four formations, Water, Fire, Metal and Wood are further differentiated into Yin and Yang formations. Clockwise which is Yang, the direction is from Zi to Chou to Xu to Hai. Anti-clockwise which is Yin, the direction is from Wu to Si to Shen to Wei. Altogether there are 8 formations. 4 Yang and 4 Yin formations. Master Yang always stressed on the basic principle of Yin and Yang. YinYang is formless whereas CiXiong refers to Yin Yang with form. Interaction of CiXiong refers to the interaction between mountain and water. Xuan Kong refers to the Qi whether Sheng Qi (thriving) or Si Qi (Dead). The auspicious or inauspicious Qi from the In-Coming mountain or Out-Going water are related and are based on the 12 Qi phase. Whether it is male/Yang or female/Yin, it is derived from within the Gua. This is referring to the Yin and Yang of the 24 mountains. This is only given to inner disciples." 

Therefore, if you believe that the YinYang Earth Plate of the SanHe LuoPan Ring, as assigned by virtue of Early Heaven and NaJia is correct, you better think twice! The YinYang Earth Plate of the SanHe LuoPan Ring, as assigned by virtue of Early Heaven and NaJia ​is mainly used for RuDiYan's Assistant Star Water Method. 

"The concept of mountain (in-coming Qi) and water (out-going Qi) which is fundamental and must be understood clearly. Whether it is auspicious or inauspicious are all due to the mountain and water location in relation to the concept of the 12 Qi phase. The mountain here refers to In-Coming and water refers to Out-Going. A concept misinterpreted as actual mountain and actual water."

Do you know why the why the Five Ghost Carry Treasure aka Assistant Star Water Method cannot work? Placing "mountains" on LianZhen position? 

"To understand this methodology, it is all within the concept of the 5 elements. This concept refers to NaYin 5 elements which is established by the 72 dragons. It is not referring to NaJia which is a different concept. The five elements are allocated in the four directions with Wood in the East, Metal in the West, Water in the North and Fire in the South. It is also allocated in the 24 mountains. The concept of turning upside down 倒倒颠 refers to the 72 dragons, where there are five elements within each of the 24 mountains. With the concept of turning upside down, there are treasures within each of the 24 mountains. There are always three elements within the 24 mountains which is usable to match the in-coming Qi and water-mouth which is the out-going Qi. Forward and backward refers to the understanding of establishing the Yin or Yang formation. Without using the correct formation there is the likelihood of meeting with fire pits. Recognize the golden dragon is to establish the formation. Metal, Wood, Fire or Water. The location and the position in relation to the water mouth and the in-coming dragons are all different. (Endless possibilities) Moving or still refers to whether there is any Qi, whether it is strong Qi or weak Qi, whether it is auspicious or inauspicious Qi. Requires the teaching from a sage."

In fact, there are plenty of clues that RuDiYan may be a bridge between SanHe and SanYuan. Replacement Star and its corresponding central and marginal reading may not be that wrong after all, if we were to take the actual reasons of 3/7 and 2/8 as the measurement of Qi intensity accordingly and not for the account of inaccurate LuoPan readings. As for the validity of the Replacement Star Ring, it has been grossly misunderstood as part of Kun Ren Yi by Jiang DaHung. He distorted and explained these verses using XuanKong DaGua thus introducing the idea of combination to 10. Coupled with the variants from the SanHe proponent, you now have the 28 confusing versions. 

Most modern SanYuan LuoPan in the market has this ring inserted just after the 24 mountain "human plate" of the SanYuan LuoPan. This is one notorious ring that was believed to have been "invented" by Jiang DaHung and being used by the XuanKong Shen JuReng Flying Star school as - the Replacement Star Ring 替星盘. Obviously it is a result of Jiang DaHung's secret oral transmission that has been reflected as a Ring, called the Leaning Star Ring  挨星盘. Different subset school of SanYuan has different way to use the Leaning Star Ring  挨星盘. Unfortunately, Leaning Star Ring  挨星盘 itself has another 28 versions. Which one is TRUE?

During the old age of Jiang DaHung, he has the intention to settle down prior to his retirement. One of his disciple, Jiang YaoShi 姜垚時 gave him a large sum of money to build his retirement home. Due to his student's generosities, he return the favor by disclosing these 10 stanzas of Leaning Star. In the Shen JuReng's XuanKong Flying Star 沈竹礽飞星派 school, this is known as the Replacement Star 替星. It was also conveniently translated into SanYuan LuoPan ring just after the 24 mountains. 

Within the 28 versions of this Leaning Star verse, 2 distinctive version stood out: -

1. Kun Ren Yi, JuMen heads come out - coined by Jiang Dahung
2. Kun Ren Yi, WenQu heads come out - the original YangGong water structure​

May the real Mc Coy please stand up?

Unlike its counterpart SanHe, SanYuan leaning star means Yang - Lean Forward and Yin - Lean Backward. Leaning forward also means that the star in this case LoShu take the forward flight path and Leaning backward means the LoShu take a reverse flight path. This is how the SanYuan school intepreted the use of YinYang of the 24 mountain "Human" Plate of the SanYuan LuoPan. Therefore, they are also termed, Yin YangYang and Yang YinYin in arithmetical connotation such as +--, -++. Such is also magnified by Jiang DaHung when he commented in DiLi BianZhen as the followings: -

The secret of SanHe 三合 and SanYuan 三元 LuoPan are within the writing of TianYu Jing 天玉經 - a single classic that can be interpreted according to both schools. TianYu Jing itself has a number of versions. But for the purpose of  discussion we shall inspect the YangGong Old Method's version and DiLi BianZhen's version. Listed herewith is the YangGong Old Method's version proudly brought to you by the late Grand Master Li SanSu, uncle to the late Grand Master Li DingXin. This version of the classic can be sub divided into the following grouping, for the ease of understanding: -

1. 72 Dragon Leaning Star 七十二龙挨星
2. Dragon Water Convergence 龙水交会
3. Investigating Dragon Riding Qi 格龙乘气
4. Differentiation of Formations 分局
5. Establishing Facing 定向
6. Pushing Sha Receiving Water 消砂纳水
7. Classification of Descendent's Luck 分公位

TianYu Jing 天玉經 - Dragon Water Convergence 龙水交会 is relevant to our topic of discussion - YinYang 陰陽 of the 24 mountains 二十四山 of the SanYuan LuoPan. There are 24 mountains. In fact, there are only 12 pairs of YinYang Dragons 十二陰陽龍. 12 YinYang all the way has within the incoming Gua 十二阴阳一路排，总是卦中来.  These 12 pairs must be aligned to form Dragon, Mountain, Facing and Water 龍山向水 (DMFW). The classics state, Topsy turvy Parents to array Dragon position, Mountain facing and corresponding Water, 倒排父母荫龙位，山向同流水. This is the structure of SanYuan (or SanHe?) in Qi connections 三元氣圖.  

Structure aside, there are only two ways to spin your YinYang. The classics state, Divide establish YinYang 2 different ways, 分定阴阳两路行. The left turning is Yang, the right turning is Yin. The classics state, left turning and right turning to arrange them, 顺逆推排定. However, left or right would only make sense from a fixed point of observation, the datum (天心). This datum is then referred to as the west or the east side of the river bank, resulting in the East River and West River sides. The classics state, divide into East and West two Gua, those who understood will announce to the world, 分却东西两个卦，会者传天下. These are the 2 different Gua – Grouping? In summary, the 12 pairs of YinYang Dragon is to identify left (Yang) or right (Yin) turning. Observe how your Qi flow is the foundation of YinYang. Others are just - crap. 

TianYu Jing also identify that the Yang Stems are all left turning - Yang (these are called Dragon God 龍神. The classics state, Jia, Geng, Bing, Ren, are Yang, left turning to find the 5 element structure, 甲庚丙壬俱属阳，顺推五行详. Dragon God 龍神 can be construed as an entire independent topic by itself... however, TianYu Jing - Establishing Facing 定向 has this to say, Front twice yielding Dragon God front  twice yielding Facing, pearl string do not face to release.  Back twice yielding Dragon God back twice yielding Facing, Arraying established YinYang counts, 前兼龙神前兼向，联珠莫相放。后兼龙神后兼向，排定阴阳算. In other word, Leaning Star polarity depends on the Dragon God 龍神.

The Yin Stems are all right turning - Yin (these are called Water Dragon). The classics state, Yi, Xing, Ding, Gui are Yin, right turning to find the 5 element structure, 乙辛丁癸俱属阴，逆推论五行. The classic did not, however, identify explicitly the rest of the 16 dragons - the 4 ordinal Gua, 4 growth branches, 4 stable branches and 4 graves branches. 

The four Ordinal Gua (surprisingly that YangGong referred to the Later Heaven BaGua) were paired respectively as the followings – GenYin 艮寅, XunSi 巽巳, KunShen 坤申, QianHai due to the double mountain and because Yin Si Shen and Hai 寅巳申亥 are the four growths of the Dragon God 龍神, they take Yang 陽.  In the method of Pushing Sha and Receiving Water, Jia Geng Bing Ren four Dragon God, entirely belongs to Yang stem element. Qian Xun Gen Kun water facing the same, nobility with access prosperity, 甲庚丙壬四龙神，俱属阳干行。乾巽艮坤水向同，富贵足兴隆. Yin Shen Si Hai water incoming without broken, 5 element facing within storage, 寅申已亥水来长，五行向中藏.

The four Graves were paired in the similar double mountain fashioned such as GuiChou 癸丑, YiChen 乙辰, DingWei 丁未, XinXu 辛戌 with the respective 4 Yin Stems and therefore they are Yin 陰. The four Stables were implied as Yin 陰. The classics state, Chen Xu Chou Wei one way move, sudden prosperity shake the family, 辰戌丑未一路行，骤富振家声. Chen Xu Chou Wei  knock against Golden Dragon,  Wealth and prosperity never cease to expire, 辰戌丑来叩金龙，富贵永不穷.

Therefore the YinYang grouping of the 24 Mountains, taking reference from the 4 Cardinal Gua and the 4 Ordinal Gua, the different grouping of the 24 Mountains is as follows: -

1. Zi, Wu, Mao, You, the 4 stables belong to Yin.
2. Qian, Xun, Gen, Kun, the 4 ordinal Gua belong to Yang.
3. Ren, Bing, Jia, Geng, the 4 Yang stem belongs to Yang.
4. Chen, Xu, Chou, Wei, the 4 graves belong to Yin.
5. Gui, Ding, Yi, Xin, the 4 Yin stems belong to Yin.
6. Yin, Shen, Si, Hai, the 4 growth belongs to Yang.
   

The static plate of Leaning Star comprising of the commonly known forward cycle and reverse cycle. The forward cycle starts from the Center 5 and continue with the sequence 6789 and follow by 1234. The illustration shown here is the forward cycle.
 
The reverse cycle starts from the Center 5 and take a reverse path with the sequence 4321 and follow by 9876. It is a reverse flow as shown by the following diagram.
 
Shen JuReng took this as his basis for Flying Star ie. odd Yang fly forward, even Yin fly reverse. Yin or Yang follows the YinYang Yang or YangYin Yin of the 24 mountains SanYuan One Ring LuoPan.
 
However, this is only the XuanKong method not SanYuan.

There is a SanYuan method for the Dynamic Plate. We called it dynamic because the 1st path that the star lean differed and not static. If you look carefully to the static plate reverse cycle, you will eventually realised that the 1st path of the star lean takes a total opposite of the 1st path the static plate forward cycle. As a result it looks as though the star leans backward like 5 4321 9876. But no. It is still a forward cycle with a different path of commencement.

It means to say, the first path that the central star leans can eventually be any of the 8 palaces within the LoShu grid and not necessarily Northwest. So, given the 8 directions, you will have 8 sets of Leaning Star as your natal chart. This is a SanYuan method of Leaning Star.

Next instalment - Dragon God

The above description is commonly found in Google. It defines in face value the 24 mountains of the SanYuan Earth Plate. More important it can be grouped and defined with its respective YinYang as the followings: - 

4 Graves, 4 Baths and 4 Stables are referred to the 12 growth phases. Stables are referred to Sickness or the Horse positions. The 4 Yang Stems and 4 Yin Stems together with the 4 Ordinal Gua complete the 24 mountains. 

Sometime back in YiFengshui since 2012 ...

… After all the heavy weights, let us come back to FengShui 101.

There are a few good books in English explaining about LuoPan, including the Compendium. However, it never dwell deep into the origin of YinYang of the 24 mountain plate of the so called, SanYuan LuoPan. It only prescribed that 24 mountain is further categorized into Heaven, Man and Earth subsector or Yuan Dragon in the manner of Yin-Yang-Yang or Yang-Yin-Yin configurations. Thereafter… nothing mentioned. To the ONE RING masters, especially from the Flying Star School, these Yin-Yang-Yang or Yang-Yang-Yin configurations are how the 9 stars “fly” forward or backward in the LoShu chart. Beyond that… nothing mentioned. So, before one worries about 明师盘线, loosely translated as Great Master’s LuoPan Line, emmm… what say if one try to find out, why do of the so called, SanYuan LuoPan has the YinYang configuration such as this?

Apparently the compendium of LuoPan is incomplete without the explanation as to where does the YinYang of the 24 mountains of the SanYuan LuoPan originated. We take for granted that it is always there in that fashion. How the PurpleWhite stars fly are all depends on its YinYang. That is already inaccurate. The Chinese source has more details. One common source is from the Shen's Classic (Shen JuRen 沈竹礽) stipulates that: -

All the Yang stems are Heaven numbers for example, HeTu heavenly number 1 takes Ren water Qi and therefore Yang in nature. Earthly 6 takes Gui water Qi and therefore Yin by nature. By the same token, Yin stems are Earth numbers and assigned Yin nature. Therefore, Jia Bing Geng Xin are all Heavenly Numbers Odd Yang in nature. Yi Ding Xin Gui are all Earthly Numbers Even Yin in nature. The same classic stipulates that all the Ordinal Trigrams namely Xun, Qian, Kun and Gen are all Yang in nature. The principle is annexed to the LoShu. Within the LoShu, there are HeTu. The ordinals take the following sequence:

Qian (6) and 1-6 HeTu water, 1+6=7, Odd number Yang nature.
Xun (4) and 9-4 HeTu metal, 9+4=13, Odd number Yang nature.
Kun (2) and 7-2 HeTu fire, 7+2=9, Odd number Yang nature.
Gen (8) and 3-8 HeTu wood, 3+8=11, Odd number Yang nature.

The branches are classify under the following groups:

1. The stable, Yin Si Shen Hai are the 4 beginning of every season. Their main Qi are respectively, Jia Bing Geng and Ren, the sub Qi are respectively Bing Geng Ren Jia with Wu in all the stables. These are all Yang stems. When each of the main Qi and sub Qi added up for each stables, it does not form combination of 10. Therefore they are Yang in nature.
2. The cardinals, Mao Wu You Zi are the middle of every season. Their main Qi are Yi Ding Xin and Gui respectively. All Yin stems. They forms combination of 10. Therefore they are Yin in nature.
3. The graveyards, Chen Wei Xu Chou are the end of every season. Their main Qi are either Wu or Ji earth. However their sub Qi are all Yin stems and therefore by virtue the graveyards are Yin in nature for its sub Qi are combination of 10 respectively.

Such is believed to have been the reasons behind the YinYang classification for the 24 mountain in the SanYuan Luopan. in reality, if you believe this is the true reason, your SanYuan applications are incomplete. Fact, YinYang does not stem from pure numerical permutations. They are the reflections of Heaven Man and Earth. Knowing thus you will understand what a SanYuan LuoPan is designed to measure. Without a throughout understanding of such, all the other Hexagram plates are nothing more then pure decorations.
