A limerick describing Mr. Yin and Yang

Hello, I want to ask what is the jingle sentence describing the teacher of Yin and Yang? The phrase describing the teacher of Yin and Yang is that the teacher of Yin and Yang is always empty, and the guide refers to the north and the west. If there is a sealed place in the world, why not find one to bury it? Mr. Yin Yang Jia, on the other hand, is divided into two types: Yang Zhai and Yin Zhai, both of which are superstitious occupations that use people's psychology of praying for good luck for themselves and their descendants to defraud money. In fact, Yin and Yang teachers also understand that it is a deceptive trick to choose a shady place to see Feng Shui. There is a jingle that is widely circulated in rural areas of our country, making fun of Yin and Yang teachers: Yin and Yang teachers are always empty, referring to the north, the west and the east. If there are feudal places in the world, why not find them and bury them?
