What if my son always sings existing songs with his own lyrics?

I remember listening to many such songs when I was in junior high school, especially when I was in primary school. Actually, you don't have to worry. When I was a child, I thought that people who could change songs like this were very powerful and talented, and they could express my feelings at that time, so I learned to sing and change songs. This is only the inevitable development of an age group. When I grow up, this situation will be much less. There may be two ways for your son to do this: first, he likes singing (in this case, you should encourage him to play his specialty in this field, which is good for his future development); Second, he is under a little pressure. You might as well take him to do some exercises with a lot of exercise, and everything will be fine when the child sweats.
