The explanation of vicissitudes of life is that heaven rewards diligence and morality carries the right path in the world.

Heaven rewards diligence from the Analects of Confucius, that is, "providence", "reward" means reward and "diligence" means diligence, that is to say, "heaven rewards diligence" God will fulfill the wishes of hardworking people. If we work hard, we will gain something. As long as we make unremitting efforts, improve and enrich ourselves to the maximum extent, and do everything possible to improve our competitive strength, we will have a bright future.

Lofty morality carries things out of Zhouyi: "A gentleman carries things with generous morality." That is to say, cultivating students with high morality and profound knowledge is now used. Tsinghua University's school motto is "strive for self-improvement, be virtuous and carry things".

The right way in the world is that endless things in the vicissitudes of the universe have to go through the process of production, development and extinction, and all exist as processes. The same is true of human society. The sea and mulberry fields are always changing, and new life always overcomes decay.
