From the Book of Changes: "Heaven is strong, and gentlemen strive for self-improvement" (dry divination), "The terrain is Kun, and gentlemen carry things with morality" (Kun divination).
It means: the movement of heaven (that is, nature) is strong and healthy, and accordingly, a gentleman should be firm and eager to be strong; The potential of the earth is thick and slippery, and the gentleman is tolerant.
A gentleman should run like Tianyu, indomitable even if he is displaced; If you are a gentleman, the measurement of objects should be like the earth, and nothing can't be carried.

Tsinghua's school motto "strive for self-improvement, be virtuous and carry things" originated from a speech by Mr. Liang Qichao in Tsinghua.
Liang Qichao had a soft spot for Tsinghua and sent his children Liang Sicheng and Liang Siyong to Tsinghua School. Both of them became world-renowned masters. At the same time, Liang Qichao himself is very concerned about running schools and the growth of students in Tsinghua. What he is obsessed with is the cultural roots of students studying in the United States. He appreciates the principles of "cultivating all-round talents and strengthening national strength" and "taking learning in virtue and striving for self-improvement as the educational policy" mentioned in the articles of association of Tsinghua University.
191410/In June, Liang Qichao gave a speech in Tsinghua, inspiring students with two images of Zhouyi. Liang Qichao's impassioned speech deeply inspired Tsinghua students. Later, Tsinghua University's motto was "Strive for Self-improvement, Be Virtuous and Carry Things".
