The white clouds gather in the clear valley, and the peaks line up in the distant sky. It looks like a stone gate, filled with smoke from the incense burner. The City of Smoke is located in the ink and wash area of Pihu Lake in Zhongshan Mountain. It is the city of clouds and smoke. It is made of smoke and ink weaving city and is extremely beautiful in the world. No one appreciates such beautiful scenery, because Yandu is a hell for women. Here, the Grand Master is the god of Yandu. Castration is a ritual rather than a punishment. Women are only used as tools for reproduction and have a low status.
