What is the Humen at home in Feng Shui?

Geographical location+placement method. . . A simple understanding is that there are side rooms or extended buildings on both sides (left and right claws). The middle of the gate is symmetrical. Two doors. There is a shaft. The threshold can be Humen. Humen trail is so deep and shady that most people can't afford to play. It covers a large area. Tiger will come out of Humen. A good soldier in wartime and a scholar in peacetime. There must be a separate bookstore at home.

This is a wealthy and expensive family.
