Teacher Yu Dan first talked about happy life and happy study. Not for parents and teachers. In a word, she said, "Knowing is not as good as being kind, and being kind is not as good as being happy." We should study with interest, so that we can master knowledge easily and happily. Secondly, she also said not to give up easily. Frustration is an inevitable growth experience in our life, and only after being tempered by setbacks will we become more mature. If you give up difficulties and study, you may give up life over time. That's quite right. Nowadays, TV and newspapers often report that some primary and middle school students commit suicide by quarreling with their families, teachers or classmates because of trivial matters. Therefore, we should learn self-control, know ourselves and others correctly, keep ourselves in a happy and simple state, repair ourselves in adversity and grow up happily.

I also understand a lot: we should learn to stand on our own feet, learn to be grateful, and don't rely on others for everything. Nowadays, many children are "little princes" and "little princesses" at home, and they are regarded as the apple of their parents' eye, which leads to the characteristics of self-centeredness and inferiority, which is not conducive to the healthy and happy personality cultivation of children. We should also learn to repair ourselves in adversity, instead of crying blindly, because crying is a sign of incompetence. Don't ask your parents everything. If your parents can't do it, say they are incompetent. We should respect our parents more.

I benefited a lot from this lecture.
