It is said that Master Li in the Song Dynasty had a loud voice during sex, which often disturbed others in the middle of the night. The porter of the brothel was puzzled and asked Mr. Shou why Miss Shishi wanted to ask for more every time she called. The uncle said angrily: She also wants a bird (pronounced DIAO in ancient times). The little doorman, who couldn't read a few words, realized that this little security guard also had the job of keeping accounts. Later, when a prostitute came out of Mr. Li's room, he would write "another bird", which meant that Mr. Li's performance had increased by one, and later he wrote "chicken".
As for the duck The allusion comes from the Tang Dynasty. Empress Tianwu was lucky enough to meet brothers Zhang Changzong and Zhang Yi. One night after the clouds and rain passed, she felt very refreshed and said: "You are the best bird in the world!" A plaque was awarded and hung in Zhang's Mansion, with five big characters on it: TWO, the best bird in the world! Glasses were not invented at that time, so many people regarded a bird as the character for duck. Later, it became a common practice to call men who sleep with women a duck!
