Mo Wen autumn wind blows hat, Qin people don't laugh at Chu people's ridicule.

This sentence comes from the humble room inscription by Liu Yuxi, a poet in the Tang Dynasty. It means, don't ask if the autumn wind is blowing hard, or the Qin people will laugh at the behavior of the Chu people. There is an allusion here. It is said that when the ancients met at the Double Ninth Festival on September 9, if the wind blew away their hats, Chu people would laugh at Hubei people's behavior, but Qin people would not. The meaning of this sentence is not to cause unnecessary ridicule and sarcasm because of trivial matters, but to maintain a certain demeanor and self-cultivation.
