What is education? The purpose of education is to realize the value of life. Education is to cultivate people's ability to feel happiness and create happiness. The essence of education is to make people happy. What is education for? The ultimate goal of education is to make life better and happier, and it is to awaken the life force to explore truth and pursue happiness. Reflecting on our education, we are confused by utilitarianism, forgetting the realization of human life and its value, losing ourselves, shielding our soul and losing our real meaning. It makes schools and classrooms that should be full of vitality, but everywhere it exudes the breath of ignoring life, distorting life and suffocating life. Therefore, if education wants to return to itself, it must come out of the past alienation and take paying attention to life, knowing life, understanding life and improving life as its basic pursuit, so as to maximize the potential of life, show the true meaning of life and clarify the meaning of life. The essence of teachers' professional mission is spiritual growth, that is, to guide the growth and generation of minor individuals' spiritual world, enlighten their beautiful feelings about life and the world, and lay a good spiritual foundation for their happy life. However, teachers are the creators of students' happy educational life, and students' happy life can only be carried out in a happy educational scene. Only when teachers "teach happily" can students "learn happily". Therefore, the curriculum reform of basic education not only pays attention to students' happy life, but also requires teachers to start the button of professional happiness and construct their own happiness.
