"Don't rejoice in things, don't grieve for yourself" is a sentence in Fan Zhongyan's Yueyang Tower. It means don't be happy or sad because of the quality of foreign things and your own gains and losses. This paper expounds that people with noble morality in ancient times are far-reaching and open-minded, and should keep an open-minded and indifferent attitude no matter what ups and downs the outside world or themselves have. That is, no matter where you are, you should be humble; Being at the peak of life is not complacent, and being at the bottom of life is not secretly sad. This sentence was said by Fan Zhongyan, a writer in the Northern Song Dynasty.
