Your uncle's education method is wrong. Teach children to be patient and not cruel to them. Many parents can't do it.

If you have children of your own in the future, you should learn from them, be patient and enlighten them, and don't be rude.

Your uncle is your relative, but the child still wants to see him and know whether it is his uncle or his grandfather. If you don't take the child to see him, you hate him. Although your uncle's education method is wrong, it is understandable that he is ambitious. The old man thinks differently. Forgive him.
