Gorky: If you really want to live a "very broad and beautiful life", create it, and work hand in hand with those who are bravely building an unprecedented grand cause. In life, there are many beautiful practical jobs, which will enrich our land and liberate people from the shameful prisoners of biased prejudice and superstition.

Pestalozzi: Is life a happy and safe life? It depends on whether he is morally honest and can set an example for the society. Therefore, self-cultivation education has become the main part of his school work.

Tolstoy: there must be a life goal, a lifetime goal, a period goal, a stage goal, a year goal, a month goal, a week goal, an hour goal and a minute goal.
