From "The Book of Changes": "The sky moves vigorously, and a gentleman strives to constantly strive for self-improvement. The terrain is weak, and a gentleman carries things with great virtue."
It means: the movement of heaven (i.e. nature) is strong and strong, corresponding to this, a gentleman should be resolute and determined, and strive for strength; the momentum of the earth is thick and gentle, a gentleman should increase his virtue and accommodate all things. .
Translated as: A gentleman should be like the sky, which is constantly moving, even if you are wandering, you will not give in. If you are a gentleman, you should be like the earth, and there is nothing that cannot be carried. In the winter of 1914, Mr. Liang Qichao was invited to give a lecture at Tsinghua University. The topic of his lecture was "Gentleman". He used these two hexagrams about "gentleman" from "The Book of Changes" to encourage Tsinghua students to work hard: "Qian Xiangyan said that a gentleman should strive for self-improvement. The movement of the heavens is endless, and there must be no shortcomings such as violent storms or cold weather. Moreover, when a scholar is determined, he must be persevering and persevering, even if he encounters ups and downs. "A gentleman blames himself very much, but blames others lightly..." After Mr. Liang Qichao elaborated on the meaning of "gentleman", he more clearly stated that "In his years, he traveled overseas, absorbed new civilizations, improved our society, and promoted our politics. The so-called gentleman is a man. If you are not a student from Tsinghua University, who will you belong to?" His encouragement is beyond words. After this speech, the school adopted the motto "Continuous self-improvement and virtue as a foundation" as its school motto, which was engraved on the school emblem at that time.
