I hope it will help you: During the Liang Dynasty in the Northern and Southern Dynasties, someone once asked a friend for beef tongue and milk. Friends are reluctant to give him cow tongue and milk. In desperation, he took out a pack of betel nuts he loved as a substitute. This incident was reported by Liu Xiaozhuo (real name Ran, small character Ashi, now from Xuzhou, Jiangsu). People who can write well are called "prodigies". 14 years, he drafted an imperial edict on behalf of his father. After learning about the works of Zuo Lang, Secretary Cheng, Ting, Prince Scheeren, Minister Lang of Shangshu Water, Prince Xima, Secretary Supervisor and others. He wrote a poem in which he mocked the man, saying that "old milk can't be expensive, bad tongue can't be valuable" and sometimes picking betel nuts "although the fragrance is not enough, I would like to have a blind date." Poetry means milk and cow tongue, stale, not so precious. It is the betel nut in the bag. Although it has no fragrance when it is just picked, it is a wonderful thing to chew and entertain guests. How much affection can it add after chewing?
