What do Fei Lian, Leopard Tail and Sangmen mean?

Fei Lian said, words are disputed, to prevent manslaughter.

Leopard tail was originally the false name of the old god in China's ancient alchemy. As a fierce god, the image of the so-called warrior and pioneer is often opposite to the old god Huang Zan. Xie Ji quoted Gan Kun Jing as saying: "Leopard-tailed man, ... where he is, he is not allowed to marry, take handmaiden, enter six livestock or get rich." The offender broke the property and damaged the small mouth. " The position of leopard tail, like robbery and Sangmen, should be taboo.
