Excerpt from Dr. Feng Shui

Maybe playing the fool is too much. Five families who were engaged to my grandmother came to see me several times and never came again. Even my parents knew that I had become a fool, so they broke off relations with me on the spot and unloaded their burdens.

Over the years, it's painful to play dumb, but grandma's meticulous care has made me happy. But when I was seventeen, my grandmother couldn't afford to get sick. I wanted to give her a diagnosis, but she wouldn't allow it.

Grandma told me three things before she died, which I must remember and can't violate.

The first thing grandma mentioned before was that I must not expose myself as a fool before the five families fulfilled their engagement, otherwise I would be in big trouble. If all five families break their contracts, if I want to live, I'll have to pretend to be crazy and sell silly.

The second thing my grandmother said puzzled me deeply. Grandma said that if one of the five families breaks the contract and the others don't, then the family that broke the contract will definitely encounter major changes. I can't gloat and must help them tide over the difficulties.
