What do you mean by the eight characters like earth gold?

The eight characters are: Bing Yin, B Wei, Xin Si, and B Wei, who are rich and weak, and cannot be born with gold. So the five elements need water to moisten them. Jin Xin likes to drain water from his body. Originally, I was fond of water, but because I was weak, I was even weaker than a financial officer. Therefore, Jin Xin, the Japanese Lord, liked Tuzhu and Jinzhu, so that he could get money.
