“In this chapter, I shall briefly describe about the three books that Yang Jun song wrote: Qing Nang Ao Yu and Tian Yu Jing. There is another text used by YangGong FengShui practitioners called YuChe Jing. It is not included in this article, but shall be discussed in a separate article.
 
This article gives students an idea of the depth of information that these three works can offer to practitioners after they are given the KEY to unlock the secrets within these three texts. It is only after a Master has given the disciple the oral transmission of YangGong secrets that the disciple can decipher the cryptic language used in these three texts.
 
Here, I would like to inform students that, out there in the market, there are many different versions of these three texts. Most of them have altered words here and there. Some of which have words that were altered that sounded like the original word but is a totally different word with a totally different meaning. Some words are totally different and have meaning of the text completely altered to suit their theories.
 
In a gist, it is very confusing out there with the many different versions of these three texts. But what is definitely sure is that the other versions propagated and interpreted by other schools have totally no connection to YangGong GuFa practices. There is another group called YangGong XinFa (YangGong New Method) that also has made many different interpretations of these three books, and causes much confusion to new students of YangGong FengShui or to FengShui researchers.
 
Everyone would claim that their interpretation is correct. This, I leave it to the student to decide because this chapter is not about debating on who is right or who is wrong. This work is purely to propagate YangGong GuFa in the way I know best. Here is a brief description of the three texts: -
 

1. Qing Nang Ao Yu (青囊奥语) is a book on the formulae expounded by Yang Jun Song. The main idea inside is the 72 dragons and how to audit internal Qi to marry with external Qi;
2. TianYu Jing (天玉经) is all about the practical usage of the LouPan and application of all the YangGong FengShui formulae. Some adherents like to say that TianYu Jing is the ‘Mother of Explanation’ of the LouPan. Thus the phrase: 天玉经是罗经解之祖;
3. YuChe Jing 玉尺经is the standard Table of the outcomes of the application of the formulae as taught in Qing Nang Ao Yu.

 
However, I would like to mention here that since Grandmaster Li DingXin of GanZhou YuChe Tang did not receive any text on TianYu Jing from his grand uncle, but only received a text called TianYu Jing Xu 天玉经序(Sequence to TianYu Jing) written by Zheng WenCan, the closest confidante of Yang YunSong, I can only comment on TianYu Jing Xu, according to Lineage practice.”

​In the GanZhou YGFS tradition, according to GM Li DingXin, although the Tian YuJing was mentioned in Li SanSu’s commentaries of Qing Nang Ao Yu (QNAY) 青囊奥语, GM Li could not find the text in his inherited collection of texts from Li SanSu. All he could find was the Outline of Tian Yu Jing (TYJ) 天玉经序 written by Ceng WenCan. However, since TYJ was mentioned in Li SanSu’s QNAY commentaries, and Ceng WenCan wrote an outline on it, it is possible that it existed. But since in GanZhou YCT there was no inherited version of TYJ, we have to be satisfied with using Ceng’s version of Outline as reference. Therefore, in this article, I shall only translate and comment on the Outline of Tian YuJing. The 2 texts Qing Nang Ao Yu and Tian Yu Jing according to GM Li are both the theory and instruction on how to use the Luopan Earth Plate and its 72 Dragons, and the Tian Pan Heaven Plate and its Double Mountains.

​These three lines, according to our YGFS tradition is referring to the LuoPan’s earth Plate (DiPan) 24 mountains and the 72 dragons attached to this ring. River East Gua means YangGong LuoPan’s 24 mountains, facing East mountains as one Gua. They are Chou, Gen, Yin, Jia, Mao, Yi, Chen and Xun 8 directions. River West Gua means the second set of Guas in the 24 mountains that face West. They are Wei, Kun Shen, Geng, You, Xin, Xu and Qian 8 directions. South North Eight Gods means
 
(i) South 4 directions facing south. They are Si, Bing, Wu and Ding.
(ii) North 4 directions facing north. They are Hai, Ren, Zi and Gui.
 
In the 24 mountains ring, all the Earth Branch mountains have JiaZi dragons attached to it. The dragon attached to a Stem or Gua is called a KongWang Dragon which has uncertain Qi. The JiaZi Dragons under these Earth Branch mountains are all placed in such a way that it has a significant sequence to it that is famously called Dian Dian Dao, which means Topsy Turvy in English. All these JiaZi Dragons have a NaYin element assigned to it. It is exactly The 60 JiaZi as used in BaZi.
 
Here I’d like to introduce a word that is always by the lips of SanYuan adherents: -
 
AiXing 挨星. It literally means ‘Leaning Star’. To the SanYuan adherents, it means the Leaning stars of LuoShu numbers that represents Trigrams and is assigned an element each. These Trigrams are also called Xing or Stars by the SanYuan adherents and is much the same as YangGong FengShui naming the JiaZi Dragons as Stars, but each have a different definition to it.
 
In YangGong FengShui, the definition is JiaZi dragons, and it also means the NaYin elements attached to each JiaZi dragon. These JiaZi Dragons withn the respective NaYin are the AiXing as mentioned in the text. River East one Gua always auspicious, of Eight Gods one have four means out of the River East mountains 8 gods or 8 Earth Branch directions’ attached JiaZi Dragons, there are 4 JiaZi dragons that belongs to the Fire Ju (formation). Here is the breakdown: -
 
i) The JiaZi that belongs to Water Ju are :- DingChou, XinChou, JiaYin, WuYin, YiMao, JiMao, Bing Chen, RenChen total 8 AiXing;
ii) The JiaZi that belongs to Fire Ju are:- JiChou, BingYin, DingMao and JiaChen, total 4 AiXing;
iii) The JiaZi that belongs to Metal Ju are:- RenYin, GuiMao, GengXin 3 AiXing;
iv) The JiaZi that belongs to Wood Ju are:- GuiChou, GengYin, XinMao, WuChen and JiSi total 5 AiXing.
 
Therefore, having 4 AiXing only within River East Guas is the Fire Ju, and this is the YGFS interpretation of ‘Eight Gods one have four.’
 
River West two Gua for arranging dragons, of Eight Gods two have four means that out of the River West mountains 8 gods or 8 earth branch directions’ attached JiaZi Dragons there are 2 Ju – Metal and Wood Ju that has 4 AiXing each.
 
i) The JiaZi that belongs to Water Ju are:- DingWei, JiaShen, WuShen, YiYou, JiYou, BingXu and RenXu total 7 AiXing;
ii) The JiaZi that belongs to Fire Ju are:- JiWei, BingShen, DingYou, JiaXu and YiHai total 5 AiXing;
iii) The JiaZi that belongs to Metal Ju are:- YiWei, RenShen, GuiYou and Geng Xu total 4 AiXing;
iv) The JiaZi that belongs to Wood Ju are:- GuiWei, GengShen, XinYou and WuXu total 4 AiXing.
 
Therefore, having 4 AiXing only within River West Guas are the Metal and Wood Ju, and this the YGFS interpretation of ‘Eight Gods two have four.’
 
South North Eight Gods combine as one Gua, deduce surely cannot go wrong. South North Eight Gods combine as one Gua means that the North Gua of Hai, Ren, Zi and Gui is only half a Gua; and the South Gua of Si, Bing, Wu and Ding constitutes the other half Gua. Therefore, both North Gua and South Gua combined as 1 Gua. When Yang JunSong transmitted QNAY to Ceng WenCan, he has already transmitted the secret of the 4 Major Water Exits based on the Earth Branch Mountains of the TianPan in relation to the Earth Plate 24 mountains. Each set of water exit comprise three auspicious exits of Grave 墓Mu, Extinct 绝Jue and Womb 胎Tai – based on the deduction of the 12 Growth Phase 十二长生.
 
Ceng WengCan wrote the OutLine of Tian YuJing also to emphasise on this secret of Mu Jue Tai water Exits via the 3 Gua cryptic message – River East, River West and North-South Gua. Out of the three Gua message: River East and River West as 1 Parent and the combined North-South Gua another Parent. Thus the term FuMu San Ban Gua 父母三盘卦(Parents 3 Plate Gua). All the while these phrases are describing the 72 Mountain Piercing Dragons AiXing of the DiPan Earth Plate as Mountain and Xue, and going together with the River (following mountain) towards the Water Exits based on the TianPan – thus Dragon and Water going via the same route and flowing out via the auspicious exits.
 
The last remaining Ju is the Water Ju and it can be found in the North 4 Mountains, where the Water Ju has 4 AiXing. The next phrase, ‘deduce surely cannot go wrong’ means if one knows the formula, and deduce accordingly, the audit would sure not go wrong. 

​Heaven Gua means the TianPan heaven Plate double mountains. ‘Earth draws 8 Guas’ means DiPan earth Plate 72 dragons AiXing. Heaven Gua River East find in the palm means that if one knows how to use the palm method to deduce the TianPan for the water exits and the DiPan to deduce the AiXing 72 dragons for sitting and facing and riding ShengQi, is worth a thousand pieces of gold. This is what is meant by ‘mountain and water relative to each other’ – knowing the rules of auspiciousness of “龙水交会” – Dragon and Water meeting. Dragon means incoming dragon and Water means river following this incoming dragon and crossing MingTang River.

​‘Parents Yin Yang search carefully, front and back together concurrently fix.’’ means to understand what Ci Xiong is. What Male and Female is. Father is Male is Ci and is Yang in nature; Mother is female is Xiong and is Yin in nature. In YangGong FengShui, Dragon or Mountain is considered as Yang; while Water/river that originates from the Dragon is considered as Yin. To ‘search carefully’ means to determine carefully and correctly which of the 72 dragon is the correct Xue (sitting). ‘Front and back together concurrently fix’ means once determined correctly the sitting, the facing is automatically obtained, and thereafter can consider whether the facing is leaning left or right. This line has to be understood together with the next line:-
 
‘Front and back concurrently look both ways, fix proportionately both sides.’ Means after determining the sitting and facing, one has to see whether the direction is leaning left or right. For example sitting Zi facing Wu, inclined to Gui Ding, GengZi Xue. And to ‘look both ways, fix proportionately both sides’ means similarly to look at the sitting and facing inclination and then fix the Xue according to the 72 Dragon AiXing position.

​‘Stay within the 8 Guas and not out of place, people of every generation will enjoy nobility.’ ‘Facing same as water flow in one direction, name famous everywhere.’ These two lines mean that one must establish the Incoming Dragon and Xue spot (sitting and facing) correctly according to the formula whereby the Incoming Dragon, Xue and Water Exit are of same Gua and not out of Gua, to receive auspiciousness that can amount to bringing nobility and fame. Gua here means the 4 Water Exit Ju or Dragon Gods of elements of Water (&Earth), Fire, Wood and Metal Ju.
 
‘Dragon walk outside of Gua no nobility, no need to waste strength.’ ‘Even though conform to TianYi and FuDe, will not see honor and glory.’ It means that when the Gua is out of place there is no need to waste efforts anymore in using other methods to rectify. It says the even using the BaZhai method of establishing TianYi and/or Fude position or location cannot reverse the inauspiciousness and bring back the benefit of glory and fame.

​‘Great concern of Heaven and Earth is fixing Male and Female’ – Heaven here means Heaven Plate or Tian Pan double mountain for establishing Water Exits and also distant hills. Earth here means earth Plate or DiPan 72 Dragons for establishing Incoming Dragon and Xue spot, and riding ShengQi.
 
Male and female here is translated from the word CiXiong which means Yin and Yang. Therefore this phrase means that it is through the connection of establishing the Water Exit and the Incoming Dragon and Xue that fixes the Yin and Yang of riding ShengQi. And if it is done right, then ‘nobility and prosperity can be found within.”
 
‘Flipping the Heaven and overturning the Earth matching not the same, the secret is in the XuanKong.’ ‘Flipping the Heaven’ means not following or conforming to the rules of establishing the Water exits via the use of the TianPan; ‘Overturning the Earth’ means not using the 72 Dragons AiXing correctly.
 
‘the secret is in the XuanKong’ – XuanKong here means the ‘Unseen Void’ or the ‘Mysterious Void’ where the mysterious workings of the Unseen creates that brings whatever auspiciousness when things are done right. Therefore based on this postulation, YGFS’s definition of XuanKong means that the correct interaction of Dragon (mountains) and Water (River) causes the ‘Creation of ShengQi.’ within the Unseen Void. It also means, directly, ShengQi.
 
Three Yang water Exits ending in original flow, prosperity and nobility forever no need to worry. Three Yang Water Exits means the Dragon and water interaction exiting Mu, Jue and Tai palaces. If the water flows is meandering slowly and smoothly out the three water Exits, then auspiciousness of prosperity and nobility is endless.
 
The two Gods uphold the Three Auspicious Six Elegant, instantly can see enter Temple hall. The two Gods here means the Dragon God and the Water God. The Three Auspisious and Six Elegant here is referring to the Qi phases of the 12 Growth Phase 十二长生 of: -
a) ChangSheng 长生, LinGuan 临官and DiWang 帝旺 as the Three Auspicious; and
b) ChangSheng 长生, GuanDai 官带, LinGuan 临官, DiWang 帝旺, Tai 胎 and Yang 养 as the Six Elegant.
 
These Three Auspicious and Six Elegant are referring to the auspicious relationship between the Xue spot and the Distant Hills and the Crossing MingTang Water. Whenever these conditions are met, it is like ‘instantly can see enter Temple hall.’ This phrase ‘entering temple hall’ means auspiciousness because whenever someone enters a temple to pray it is auspicious.

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.
