Pei Songzhi in the Southern Song Dynasty quoted Jiuzhou Chunqiu as saying: I lived in Jingzhou for several years and tried to sit on the table and go to the toilet, but when I saw the meat in my moustache, I cried. Still sitting, I looked strange and asked about the equipment. I'm always in the saddle, and my beard is gone. If you don't ride today, you will be born in a moustache. The sun and the moon go by, the veteran arrives, and the achievements are not built, which is sad.
