Wang Yisheng-nicknamed "chess nerd", chess genius, fascinated by chess. "Eating" and "playing chess" are the few pursuits in his life, but they are not excessive. "Eating" only seeks satiety, while "playing chess" only solves worries.

As a narrator, I met Wang Yisheng, a chess fan, on the train to the countryside, and had a similar tragic family situation with Wang Yisheng. Love reading.

Full-fledged rich boy, whose real name is Ni Bin, has elegant speech but good personality. Because the feet are long, they are called "eggs" in the local dialect. Chess is good, but only for fun.

The painter is a friend that Wang Yisheng met in the county. He is generous and helpful.

Secretary-a friend of Daddy Foot Egg.
