I like listening to teacher Hu Songhua's songs since I was a child. I have seen the teacher sing them many times on TV before. Teachers play much less now. About the teacher's hair More than 20 years ago, the teacher's hair was like this. Big curly hair was fashionable at that time, so there should be no problem. You care about the teacher's hair, which shows that you care about the teacher's health. You are an old fan.
