Who can help me explain the four words that Chairman Mao said?

The motto of Mao Zedong's "Anti-Japanese Military and Political University"-unity, tension, seriousness and vividness-is not only collected in quotations, but also written beside the iron barracks of mobile soldiers, and can also be used in many places, spiraling upward and advancing in waves, which is worth savoring. "Practice, understanding, re-practice, re-understanding, this form is endless, and the content of each practice and understanding cycle is relatively advanced to a higher level."

Unity, tension, seriousness and liveliness. Two pairs are quite antonyms, put together but not contradictory. Things themselves are contradictory and mutually transforming bodies, and we choose in constant wandering. The more you experience, the more you understand sharp words, and the more you can stab people. But China people also pay attention to harmony and balance, so many things can't be said too bluntly. Tao can be Tao, but it is extraordinary. Experience it for yourself.

My understanding is that this statement can be a statement, a standard and a state.

The purpose of putting forward this sentence during the Anti-Japanese War is very clear. Strategically, we should unite all forces that can be United, and brothers should help each other and bear the burden of humiliation. Tactically, GCD mainly adopts guerrilla warfare and mobile warfare. When the enemy advances, I retreat; when the enemy is stationed, I disturb; when the enemy is tired, I fight; when the enemy retreats, I chase. Strategically despise the enemy, tactically attach importance to the enemy, pay attention to details, and be informal.

Self-cultivation, governing the country, leveling the world, unity, nervousness, seriousness and liveliness are all good guidelines. The same is true for individuals, and that's what life should be like. Never give yourself a stereotype that "everything is beautiful", and the so-called best fit is the conclusion you keep trying to reach.

If you know this history and its background, you can consider it as a class style. After all, it's what you want.

Ten years in the forest, a hundred years in the forest. It has been used as a warning for generations, and we are lucky to continue to use it.
