What is the Trang Sinh water method and why is water read by direction?
The Trang Sinh water method reads the flow of water around a grave or a house based on the twelve Trang Sinh palaces of the earthly branches, rather than looking only at the shape of the water. According to the cited Dia Ly Gia Truyen Bi Thu Dai Toan, the water method is founded on the Trang Sinh ring, which has twelve palaces: Trang Sinh, Moc Duc, Quan Doi, Lam Quan, De Vuong, Suy, Benh, Tu, Mo, Tuyet, Thai, Duong. Among these, some palaces are considered good and some bad. Water arriving or pooling should be placed in a good palace, while in a bad palace water should be let out.
This is the basic difference between the two approaches. Loan dau examines water by shape: whether it curves or runs straight, embraces or stabs, pools or scatters, and whether there is a sand bar locking the water mouth. Ly khi examines water by direction: where the water comes from, where it leaves, and which palace of the Trang Sinh ring it falls into. A flow of water may be good in shape yet offend in direction, and the reverse.
It should be said clearly at once: Tam Hop here is the name of a water cuc system based on Tam Hop earthly branches, and has nothing to do with birth-year compatibility or clash between people's ages.
How are the twelve Trang Sinh palaces placed?
Each water cuc has an earthly branch where Trang Sinh begins, and from there one counts forward to place all twelve palaces. The four common water cuc are Thuy cuc, Moc cuc, Hoa cuc and Kim cuc, each tied to a set of Tam Hop earthly branches.
| Water cuc | Tam Hop earthly branches | Trang Sinh begins at | De Vuong | Mo kho |
|---|---|---|---|---|
| Thuy cuc | Than, Ty, Thin | Than | Ty | Thin |
| Moc cuc | Hoi, Mao, Mui | Hoi | Mao | Mui |
| Hoa cuc | Dan, Ngo, Tuat | Dan | Ngo | Tuat |
| Kim cuc | Ti, Dau, Suu | Ti | Dau | Suu |
For example, with Thuy cuc: Trang Sinh at Than, Moc Duc at Dau, Quan Doi at Tuat, Lam Quan at Hoi, De Vuong at Ty, Suy at Suu, Benh at Dan, Tu at Mao, Mo at Thin, Tuyet at Ti, Thai at Ngo, Duong at Mui. The other cuc are derived by the same counting.
How do receiving water and discharging water differ?
Receiving water means letting water arrive and pool in the palaces regarded as prospering: Trang Sinh, Moc Duc, Quan Doi, Lam Quan, De Vuong. These palaces represent growth and development, so water pooling there is seen as favourable for the wealth and reputation of the family.
Discharging water means letting water flow away in the declining palaces: Benh, Tu, Mo, Tuyet, Thai. These palaces represent decline and exhaustion, so water flowing away there is seen as helping to dispel misfortune. By the same reasoning, even a flow of water reputed to be a sat can be neutralised if one manages it so that it exits at the right palace.
The boundary between "should receive" and "should discharge" is not a fixed line for every cuc, but shifts with the water cuc in use. The same direction may be a prospering palace in one cuc and fall into the Tuyet palace in another.
How do the four water cuc by Tam Hop earthly branches operate?
The four water cuc are simply four different Trang Sinh rings, each beginning from a different earthly branch. So when reading a grave or a house, the first step is to determine which water cuc applies, and only then compare the incoming and outgoing directions of the water with the twelve palaces of that cuc.
This division into cuc is based on Tam Hop earthly branches, that is, groups of three branches four positions apart on the earthly plate. This is why the name Tam Hop attaches to this water method. It should be stressed again that this concerns the water cuc and the earthly plate, not the birth-year Tam Hop of the householder.
Some documents also place this Trang Sinh ring alongside other methods such as Tu Long Thien Tinh, holding that a flow of water may wind through many bends but the essential point is that it must harmonise with the long mach. In other words, the water method does not stand alone but must be read together with the mountain configuration.
What is Hoang Tuyen sat?
Hoang Tuyen sat is the general name for combinations of direction and water flow regarded as carrying strong sat khi, which may bring harm to the householder if water flows into the minh duong or if the sitting direction offends certain opposing pairs. This concept is tied to the water mouth, that is, the direction in which water flows out, and to the sitting direction of a grave or house.
Two names are commonly met. The name Bat dai Hoang Tuyen emphasises eight combinations of direction and water. The name Tu lo Hoang Tuyen emphasises four water paths. The compact verse repeated in many documents is "Khu lai thuy lo bat dai hoang tuyen".
Within this system there is also a separate group called Hoang Tuyen sat thuy, tied to the four branches Thin, Tuat, Suu, Mui, that is, the four Mo. The cited view is that water in this group flowing in is inauspicious, while flowing out is good; offending it may lead to early death and ruin.
The Bat dai Hoang Tuyen verse and its meaning
One surviving Hoang Tuyen verse reads: "Dinh, Canh, Khon thuong thi hoang tuyen. At, Binh tu phong Ton thuy tien. Giap, Quy huong lai huu kien Can. Tan, Nham thuy lo pha duong Kien."
Meaning: the directions Dinh, Canh and Khon are places of hoang tuyen; At and Binh must guard against water coming first from Ton; Giap and Quy as incoming directions should not meet Can; Tan and Nham, if there is a water path, offend Kien.
| Verse line | Directions named | Offending element |
|---|---|---|
| 1 | Dinh, Canh, Khon | These directions themselves are hoang tuyen |
| 2 | At, Binh | Water coming from Ton |
| 3 | Giap, Quy | Meeting Can |
| 4 | Tan, Nham | Water path on the Kien side |
It should be noted that this verse is only one version. Hoang Tuyen versions circulating among the people and in various books do not fully agree on the pairs of directions and pairs of earthly branches named. So when consulting, the reader should know which version is being cited rather than treating it as the only correct one.
Why do Hoang Tuyen verses not agree with one another?
There are at least three reasons why Hoang Tuyen versions differ. First, different cuc: the same pair of directions, applied to Moc cuc or Kim cuc, shifts the positions of Thai, Mo, Tuyet, so the directions named also change. According to the cited document of Cao Trung, when the long belongs to Moc cuc and water is received at the Thai, Mo, Tuyet positions, these correspond to Canh, Dinh, Khon; or if one sits Dinh while water comes from Canh, sits Ton while water comes from Ton, sits At while water comes from Binh, then each may offend Hoang Tuyen huong or thuy sat.
Second, different counting: some documents count by the house direction, some by the incoming water direction, and some by the outgoing water direction. These three ways of counting yield three different lists.
Third, different transmissions. The same method, copied over many generations, has a few characters changed, and one changed character changes the whole pair of directions.
So the reasonable way to use it is to choose one consistent version, state clearly which version is being followed, and check against the actual site before concluding.
How is Hoang Tuyen sat said to be neutralised?
The core principle stated in the documents is to adjust the flow of water and choose a suitable direction. Since the main cause of harm is said to be receiving water into the minh duong at an offending position, the first remedy is to let water that offends Hoang Tuyen flow out rather than enter the minh duong.
In other words, this method does not emphasise suppression by objects, but emphasises leading water along the right path. This is also why the water method is regarded as the difficult part of geography: one wrong outlet direction can reverse the outcome of an entire site.
How does Tam Nguyen reading water by van differ from Tam Hop?
The Tam Nguyen school does not read water by the Trang Sinh ring of the earthly branches, but by van. The book Nhap mon loan dau: tam long diem huyet has a passage on the Huyen Khong phi tinh method: a direction whose huong ban tinh is prospering benefits from meeting water, while a direction whose huong ban tinh is declining should not meet water, otherwise loss of wealth commonly follows. The book also notes the case where a direction whose son ban tinh is prospering but obstructed meets water, commonly causing loss of people, while a direction whose son ban tinh is declining meets water, which may turn inauspicious into auspicious.
According to this book, water is called linh than, with the line "Thuy la linh than, cat loi. Thuy la Chinh than, hung hoa". The book also says that in application one must combine the 48 cuc thuan tu and nghich tu. Thus the same flow of water may be judged good or bad by Tam Nguyen depending on the governing van, while Tam Hop judges by the fixed Trang Sinh palace of the cuc. The two schools may reach opposite conclusions on the same site, and that is normal in phong thuy.
The book Dia ly Nguyen Khong Phap Giam by Lien Tri tien sinh follows yet another line when discussing the water mouth by kim long and tien thien bat quai, dividing ban nguyen thuy khau and ngoai nguyen thuy khau, with a distinction of thuan cuc and nghich cuc according to ta thuy or huu thuy. This is a third frame of reference, matching neither the Trang Sinh ring nor phi tinh.
Points to be cautious about when reading the water method
According to the documents, a practitioner of geography who does not master long thuong bat sat and Bat dai Hoang Tuyen will find it very hard to create fortune for the householder. Yet these same documents show the degree of disagreement between versions and schools.
So when meeting a claim such as "offending Hoang Tuyen surely brings early death and ruin", the reader should take it as a statement within the framework of a particular school, not an absolute conclusion for every case. The water method is a frame of reference for reading the terrain, and its value lies in forcing one to observe carefully where water comes, goes and pools before making any judgement.
