Earlier article has mentioned the below mapping:
Ten Heavenly Stems into River Map numbers
As numbers 3, 8 for wood, so 3 for Jia and 8 for Yi.
As numbers 2, 6 for fire, so 7 for Bing and 2 for Ding.
As numbers 9, 4 for metal, so 9 for Geng and 4 for Xin.
As numbers 1, 6 for water, so 1 for Ren and 6 for Gui.
As nymbers 5, 10 for earth, so 5 for Wu and 10 for Ji at centre core.
Guess some may know how the mapping rules work, however some may need little explanation below:
- Odd numbers are for yang, even numbers are for yin.
- River Map numbers group by 5 element nature, eg 1,6 for water, 2,7 for fire, etc.
Therefore, 1 is for yang water = Ren
2 is for ying fire = Ding
3 is for yang wood = Jia
4 is for yin metal = Xin
6 is for yin water = Gui
7 is for yang fire = Bing
8 is for yin wood = Yi
9 is for yang metal = Geng
5 is yang earth = Wu
10 is ying earth = Ji
As you can see, the the theory consists of various principles and rules for strictly adherence.
