Why can't you leave your relatives and friends at home easily? What are the feng shui taboos?

Borrow custom: "Borrow death but not life", where death refers to a person whose spouse is dead and life refers to a pair of living people. People who don't have a spouse won't have sex in their master's house. A couple or lovers who borrow someone else's house will inevitably share the same room and destroy the master's feng shui. Many people don't know this now, so don't lend it to others in the future, especially if you know he will live with others, let alone provide it. If he is single, it doesn't matter (as long as he doesn't bring a roommate). Besides, it is not good for a married daughter to share a room with her parents. This is a tradition left by the older generation, and few people know it now.
