Feng Shui says it's good to keep a black cat.

Black is an unlucky color, and black cat is a symbol of evil and death. However, the feng shui master you hired is just a liar. He doesn't even know the five elements of feng shui. Let me give you a simple suggestion. Yan is a symbol of death. Are you afraid to be friends with Yan? Similarly, a black cat is evil and unlucky, but when it is on your side, hehe, get it?
