One rarely heard of this ring in modern LuoPan. It only use to explain but not used as application ring. Therefore it rarely appeared in the standard 8"6 LuoPan.
 
These 240 dragons are single unit measurement of Heaven and Earth Qi. Just like scales of 0 - 10 (max). The scale of Heaven Qi moves in total and opposite direction of Earth Qi. So, at any point of the maximum Qi of one shall be the empty Qi of the other. For this reason it is called emptiness or void. In YangGong terminology, it is called KongWang dragon. As to why it moves in an opposite direction is beyond the scope of this paper.
 
The first set of 240 dragon is fixed to the earth plate while the other 2 sets are fixed to the Human and Heaven plates. With these 2 plates of Man and Heaven, being tilted 7.5 degree offset from the middle of Zi earth plate, they overlapped each other. When these overlapped scale is used to read against the 240D of the earth plate it gives you a combination of 10-0, 5-5, 3-7, 7-3, 2-8, 8-2, 6-4 and 4-6. These combination of tens are the most accurate definition of what combo 10 comes about commonly in XuanKong and DaGua. These are the best composition of Heaven and Earth Qi. At this point, the Center of all the earth branch mountains from Zi to Hai are 10 Maximum earth Qi with 0 Heaven Qi. That is why, the Center of these mountains are very pure earth Qi. By the same token, the Center of Heaven Stem and Gua of the 24 mountains namely from Jia to Gui and the Ordinal Gua of Xun, Kun, Qian and Gen are 10 Maximum Heaven Qi and 0 Earth Qi.
 
Because these Stems and Gua has 0 earth Qi, they are deemed to be empty in earth Qi. These 12 dragons are called DE dragons with 正 or Direct indicated in the LuoPan. Whereas the rest of the 60 dragons are arranged alongside together read as 72 dragons ring, the most important ring of the SanHe LuoPan.
 
The 72D ring is therefore used to measure 'incoming dragon' or earth Qi. Some school who believed in Xue equal incoming dragon will use it to measure Xue. Therefore it is major inauspicious if tombs or houses sit these 正 dragon or major DE because the dragon carries no earth Qi.
 
By inference, the 7-3, 3-7 and vice versa are well balanced mixed Qi often seen attached to the 60 dragons of the human plate. These are again beyond the scope of this paper. The boundaries between these 72 dragons are minor DE or Xiao KongWang. In fact, these are the worse effect of DE dragons especially those between YinYang dragons.  

The KingPin of YangGong old method, the late grandmaster Li DingXin is a reputable teacher in this area. With his passing, his lineage is carry on by his son. Via his webpage, anyone who can read Chinese would know that his lineage was not pass down to any con master in Bolehland. In fact one has hurt him so much that he has never been forgiven even to his deathbed. This is first blood drawn.
 
There is one occasion where a con master of Bolehland  after being booted out by his master, the late grandmaster Li DingXing for being 食碗面翻碗底, a Cantonese idiom of being disloyal, challenged the grand old man of his knowledge that he has acquired from his great great grandfather the knowledge of DE or DaKongWang that the late grandmaster has no idea what is it about. This piece of knowledge is again being sold for USD 20,000.00 in the market, we called it Fake DE dragon. One former student of the con master called it Shit Dragon formula.
 
What has been taught is that, we can still sit DE 正 and only if we know what frames or structure to follow. Only those idiots who was not taught the secret arts by this con master would not know how to deal with DE 正. So for the benefit of the doubts, we are sharing herewith the fake DE dragons should follow which frames as the followings (only 6 are shown, the rest shall be emailed to you upon request with donations): -

DE stands for Death and Emptiness. It is a point in which the law of 'FengShui' breaks down, just like theoretical physic's Black Holes. One reason is that it is a point in which the Qi is too pure too intense to be use by normal people. Unless you are abnormal meaning, being a saint, absolutely noble person or being a monk without descendants. Therefore, by definition it is very inauspicious to set the grave or abode on a DE line.

DE is qualified further to minor and major. At an entry level DE minor is the boundary between each of the 24 mountains. These are the boundary of confused Qi. Sitting such will not give an accurate reading of the LuoPan. Therefore, a house sitting DE minor fails to establish sitting and facing. Especially true for practitioners of Sheng's Flying Star method, where a mitigation method called replacement stars are employed.
 
Within the DE minor, the boundary between two different YinYang mountains are the worse of the lots. If the YinYang is the same, the effect is less severe. However, since the YingYang of the 24 mountains differed among schools, not everybody would agree on this matter.
 
DE major are all the 0, 90, 180 and 360 degree of the LuoPan directions. These are the direct Zi, Mao, Wu and Dui mountains. It marks the exact Cardinal and its Qi is said to be very pure and intense. Only temples and places of worship could use this direction.

Establishing the accurate sitting and facing is the fundamental of Flying Star to know how the star would fly within the LoShu Grid. The YinYang of the mountains would dictate how the stars fly forward or reverse. In the event of a DE or 3 degree within the DE, a method called Replacement Star could be afforded.
 
Therefore, once the sitting is 3 degree close to the boundaries of the 24 mountains, a new flying star natal chart can be drawn by replacing the facing and sitting star with the replacement stars. Shen uses the Jiang DaHung 9 stars ring as the basis of the replacement stars. However, this is not a genuine replacement star method.

For the DaGua school, besides the boundaries separating the 24 mountains, there are also the 32 lines separating the HeTu Pairs of GuaYun. Due to overlapping, there are altogether 48 DE and these as far as XKDG is concerned are pathways to the Hell and the passageways for spirits. Very malignant for both tombs and houses. It becomes very real and likely for a building to sit DE.
 
For the 240, 120, 72, 60 dragons method, the boundaries between these dragons are DE minor. Only in 72 dragons one is able to find DE major that is 12 of them together with the 60 dragons made up the 72 dragons. To appreciate such delicate theories, one has to understand the following explanation by the late grandmaster Li DingXin...

We heard another fake YangGong FengShui theory in the market, both in Bolehland and the cradle of FengShui in the Middle Kingdom. This fake theory is related to the 5th element - earth. Such brandished theories are sold at a ransom USD20,000.00, to cheat the masses especially those from the west. 
 
The late Grandmaster Li DingXing has been openly disclosing the fact that there are only 4 structures or SanHe frame in the YangGong old method such as Wood, Water, Fire and Metal. This is as prescribed in Jade Ruler Classics 玉尺䫎

Qi connection is a standard operating procedure SOP for practitioner to set up a FengShui formation. He must able to connect the internal structure with the external. Both SanHe and SanYuan schools shared the common approach but they termed it differently.

In SanHe, the Qi connection can be summed up as Incoming Dragon, Embrace, Meridian and Outgoing Water. Therefore, incoming dragon and Meridian or Xue are entirely different things. When these 4 aspects are connected, that is what is termed as riding Qi.

I was reading a blog page about Yin FengShui and I was having a second thought about what has been written. So, I took the liberty to gloss over the script and to speak my mind out as loud as possible for the benefits of others reading this blog page for free…
​
FengShui is rarely a technique of using beneficial Qi in the Universe and less so with the employment of Heaven Qi and Earth Qi to assist in Human endeavors. The utilization of Heaven and Human as in Heaven and Man combine as One, is nothing more than the ability to use the art of prediction to the highest level. This is not FengShui. Strictly FengShui is all about utilization of Earth Qi. This term is derived from GuoPu’s writing, the Burial Classics that state - First obtain water then barricade wind or vice versa...

The importance of Yin house FengShui does not lies on the fact that Heaven Qi and Earth Qi intercourse more naturally and easily in the country side to give birth to the most powerful ShengQi. In the 240 Rings of all the three 24 mountain rings in the SanHe LuoPan, the postulation of ShengQi is construed as the combination of Heaven and Earth Qi in the principle of 30%-70%. This is where the basis of ShengQi gold division is arrived at. Yet, it has nothing to do with the art of acquiring Qi. QingNan Zhu states – YangGong old age watched CiXiong, all books in the world say different things. Such is really the secret of FengShui.

The art of Yin house FengShui was known beyond the art of benevolence and filial duty 仁孝之術. It is not magic as marketed by a lot of fraudulent FengShui "masters", we called Conman. The common impression is that if your ancestor is buried in a wonderful dragon's node 龍穴, then you will be rich and famous in no time. Yet, they never tell you what a dragon’s node 龍穴 is. If you buy in to believe that it is the so called, YuHan Jing 60 dragon rings that is being sold by a con master of Bolehland, to measure a hole as tiny as a “pin-head”, then you are really been taken for a ride!

The secret of Yin house FengShui lies in the requirement of the descendants visiting the grave site every now and then is a misleading statement. They must spend some time there to get the benefit of the sheng qi in the dragon's node 龍穴 is even more misleading. If that is true, you might as well built a house by the side of the grave to receive the Dragon Qi? These are all the extension of Con-master teaching craps to students from the west. A lot of Yin FengShui case study revealed that rich and power tycoons graves are nothing more than a simple grave, sometimes located in lousy land form. If you do your homework well, you will learnt that whatever being taught and said in books are not the real FengShui. However, it all conforms to a single thing called – Structure within the notion of SanHe. Merely burying the dead there is a waste of good FengShui, if you do not know the secret of “YangGong old age watched CiXiong”. You have to be there frequently thinking about your ancestors there so that Heaven, Earth and Man Qi can mingle well to help you is really nothing more than day dreaming!

Forget about the formulas invented in the past, as was sold to you by Con masters. They never work and will never work. The most important ingredient is the burial must acquire Qi. It is not enough if you are present there and your feeling is good, this is nothing more than New-Age feel good practices. By such doing, that means the FengShui there is good for you, that is really called bull-shit! Many real tycoon making Yin FengShui graves are not properly kept and almost ‘abandoned’. Go and see for yourself graves liked EuYan Sang, Kuok Brothers, Plastic King and so forth. They are never in the modernized memorial parks but public cemetery.

If you understand this little article, you do not need to take any course with any of the con-masters famous or otherwise and you will be better than those who have bought the title of FengShui Master or Grandmaster after spending a few days to learn from a so-called Sifu.
