2. In the discussion of Yin-Yang and Five Elements, the second part of heavenly stems belongs to the wood of Yin, and the unitary part of earthly branches belongs to the gold of Yin, which is Jin Kemu's xiangke, corresponding to the water in Yin Na and Five Elements Spring, the so-called self-destructive water, and the fake gold is used to cover up my weakness. I raised my mother, so I avoided my own integrity, my own meanness, my Shen Wu, my son, my ugly land, and then I died. In ancient times, yiyou was also a method to calculate time, but it didn't refer to a certain year, because there was a 60-year cycle, so yiyou referred to the 22nd year in the 60-year cycle in the main branch year. In addition, in the four columns and eight characters, yiyou represents different meanings in different columns? That is, yiyou annual column, yiyou moon column, yiyou sun column and yiyou time column have different influences on the Japanese Lord.
