What if students make mistakes and don't change their teaching?
Personally, I think teachers should communicate with parents in time, which is responsible for students. If teachers don't inform parents in time, how can parents know what students are doing at school? I have a friend who takes a class called Hongwei Education in Xizhimen. He also takes care of some children every day, but those pupils are afraid of him! So first of all, let them take you from their hearts, so as to control it!
