What's wrong with using dry wells in houses?

As the saying goes, the owner of the mountain is the owner of wealth, and the ancient well is a symbol of wealth, which means that it is a place to gather wealth, so the well is both a place to gather wealth and a place to go to the underworld, so one is yin and the other is yang, but the door is facing the dry well, which means failure and everything is in vain.

The poem says: the yin and yang of the dry well are the masters, and everything is empty to the dry well. After three years of family wealth, it is difficult for husband and wife to be white.
