There is no official motto of Peking University, which is "erudite, questioning, thoughtful and discerning", "patriotism, progress, democracy and science" and "freedom of thought and inclusiveness". Slogans put forward in the development history of Peking University

Tsinghua school motto: strive for self-improvement, be virtuous and carry things.

"Book of Changes" two sentences: one sentence is "Heaven is healthy, and gentlemen are constantly striving for self-improvement" (dry divination); One sentence is "the terrain is Kun, and the gentleman carries things with morality" (Kun Gua). A gentleman should run like Tianyu, even if he is displaced, he is indomitable; If you are a gentleman, the measurement of objects should be like the earth, and nothing can't be carried.
