I think you're right. There is only one reason why I don't like people touching him. I think your child may be very principled. If someone accidentally touches him, he will think that he hit me and should apologize to me. Otherwise, it is malicious. If you care about your child so much or talk to him, he will think that he is making a fuss or even different, so that you won't share toys with him or even stay away from him, in case you accidentally "bump" him.

Let children know the concept of "beating". Parents should let their children know that there will be these casual touches in public places outside. In this case, it's not a fight, because people are not careful and even others don't realize that they met you, so naturally they won't apologize. You can't think that a child is not a good child just because you are in your heart.

Basically, for children in large classes, teachers will not interfere too much with the contradictions between children, but generally let the children solve them themselves and cultivate their ability to face and deal with problems independently. You can talk to the teacher, or try to get to know your child from other children and see why other children don't play with him. Then make corresponding adjustments.

You can also look at the family environment, whether to give children too many constraints, let children know some moral norms too early, and establish some standards too early, so that children will be bound. Then use the same standards to ask his companions so that like-minded people can get along well. Others will be rejected by his heart, and it is relatively difficult to adapt to others.
