What are the five elements of children born on Geng Yin's birthday?

The eight-character Geng was born on the moon, and the original bureau was weak. Xi Ding, Wang Cai, eight characters and five elements, although Geng Xu is chaotic, printed as the source. Although Ding Huo is weak, it has yin and wood, yin and water, and water and gold. So there is no shortage of eight characters and five elements. Relatively speaking, he was in a weak position in the original bureau, and Geng took Ding as an official, so he could make up for the fire and help it.
