What are China people like in Russian jokes?

I used to watch other boys throw basketball at girls to scare them, but I didn't throw it. One day in physical education class, my crush sister stood by and watched me play basketball for the first time. I was wrong: "Catch the ball." I didn't expect to get rid of the ball and fly directly to my sister's face. Suddenly, my sister's nosebleed was sparse. . . After that, the girl never spoke to me again. . .
