? I have talked about the standards of being a good teacher and a good student before, as well as why teachers teach, why students study and why schools exist. These are inconclusive, at least incomplete, because the competition between species and within species is really fierce. No one knows why genes torture all animals so much that they have to compete for resources at the same time, even eating each other or one side-or robbing others of food.

? In particular, human beings are not satisfied with survival at all. They must pursue instant enjoyment, safety and significance, and even pursue living for a few more days at all costs. For the unreachable appearance of life, human beings have spent countless possessions, but generally turn a blind eye to those who are still suffering from war, hunger and disease. Sporadic public welfare is a drop in the bucket after all.

? If material resources are limited and all animals must have natural laws of life and death, then spiritual resources can be infinite forever, right? Let people think deeply, truly control their own destiny, and not be too greedy. Isn't it the highest state of human pursuit of happiness? I don't know why power, wealth and immortality have so much control over mankind.

Education, teaching people and skills, but not teaching people and teaching Tao, are not all exquisite egoists in the end, but all kinds of desperate competition and pressure in the end. Anti-humanity or obedience to humanity, or borrowing humanity, are incomprehensible. Human beings' pursuit of respect is obviously far less than interests-if interests are given enough, countless people can lose their dignity and face. Some people's so-called face is just because you can't give him benefits, so you have to give him face. If this is the case for most people, you can only face it.
