"Heaven is strong, and the gentleman strives for self-improvement", and the next sentence is "the terrain is rich, and the gentleman carries things with morality". Tsinghua's school motto, two sentences mean: the movement of Heaven (that is, nature) is strong, accordingly, a gentleman should do things in Heaven, strive for self-improvement, be resolute and resolute, work hard and not be lazy; The earth absorbs sunlight and nourishes everything. A gentleman should increase his morality and set an example. A gentleman should run like a celestial body; If you are a gentleman, measurement should be like the earth, and nothing can't be loaded.
A gentleman learns from the image of being vigorous, staying in heaven, and constantly striving for self-improvement, learning from virtue. "Yi Zhuan" said: "Heaven is strong, and gentlemen are constantly striving for self-improvement."
