What should I do if I am not good at basketball and am often laughed at?

It doesn't matter if you don't play well, have confidence and don't give up because of other people's jokes; Choose the right venue when you play, because when you start learning, don't play with people who are tall and skilled, so you will suffer more and you won't be improved. Just find someone taller than you and play basketball for a while, so that you can learn something and be motivated. Practice more at ordinary times. At first, the practice method was simple. Don't think you can become Iverson at once. Start with the ball, first shoot in situ, contact the flexibility of the wrist, then dribble, first shoot with one hand, then shoot with both hands at the same time, and finally practice with your hand (left hand). Shooting and shooting can be interspersed with practice, first in-situ free throws, and then jump shots;

The key is to keep practicing!
