This is not a poem, but a sentence from the "Book of Changes". The author of "Book of Changes" is King Wen of Zhou Jichang. The school motto of Tsinghua University is also quoted here. ?As heaven moves forward, a gentleman strives to constantly strive for self-improvement?

This is a famous saying that we have known since childhood. The general meaning is that a gentleman should constantly strive for self-improvement and be virtuous like heaven and earth. It also tells us that a gentleman must have a broad mind and a strong mind. I hope all young people can become a gentleman. In our impression, "The Book of Changes" only contains some Five Elements and Bagua, but many people have not realized that "The Book of Changes" also has some more profound philosophical sentences. The content of "Zhouyi" includes two parts: "Zhuan" and "Jing". "Jing" is mainly used for divination, and "Zhuan" is used for interpretation of hexagrams. The Book of Changes does not include Yin Yang and Tai Chi, both of which were created by the Yin Yang family. "Book of Changes" appeared during the Zhou Dynasty. The Yin Yang family appeared in the Spring and Autumn Period and the Warring States Period. There is a long time difference. I hope you will not confuse these two things. Since during the Zhou Dynasty, people did not have a certain understanding of nature, and no one could make a reasonable explanation for natural similarities, so people began to worship gods and tried to use hexagrams to measure good or bad luck and the weather. to avoid disaster or take corresponding measures. After people's long-term experiments, people invented a prediction method for communicating with gods, and this method was recorded in the "Book of Changes". When we usually watch "The List of Gods", we know that Ji Chang is very good at divination and interpretation of hexagrams. He once accurately divined how much rain the Dragon King would rain, and the Dragon King was demoted because of it. Therefore, people speculate that the book "Book of Changes" was created by Ji Chang. "The Book of Changes" is not only about divination and hexagrams. After the Han Dynasty, "The Book of Changes" also included the philosophy of cultivating one's health, cultivating one's character, and governing the country and settling one's family. Therefore, "Heaven moves vigorously and a gentleman strives for self-improvement" to appear in the book "The Book of Changes" among. If you have time, I recommend everyone to read this book.
