Hidden Stems

For those into Bazi, the concept of Hidden Stems are very crucial in the analysis of a Bazi. So I have put here the poetic oral formula used in ancient times to help memorise the Hidden Stems in all the 12 earth branches:

子宫癸水在其中，丑癸辛金己土同。寅中甲木兼丙戊，卯宫乙木独相逢。
辰藏乙戊三分癸，巳中庚金丙戊丛。午中丁火并己土，未宫乙己丁共踪。 申位庚金壬水戊，酉宫辛字独丰隆。戌宫辛金及丁戊，亥藏壬甲是真踪。

Serious about Bazi? Then you must digest this and know it like the back of your hand.
