The cuckold is a derogatory term. How did this word come from?

In modern life, "cuckold" is a derogatory term, but it is often used in life. So how did it come from? People are used to saying that people who have non-proper relationship wives are cuckolded. How did this statement come from?

It originated from the managers of ancient teaching workshops, and their regulations must be green headscarves. It seems that Zhu Yuanzhang has clear regulations on this. In Lang Ying's Seven Revised Manuscripts, there is such a description: "... people who call their wives adultery are called' green headscarves', and now people are entertaining, and their heads are covered with green towels ..." He Mengchun, who is a little later than Lang Ying, also wrote in "Winter Preface": "The system of teaching and visiting commanders' benevolence is often covered with green towels, which is used by other scholars." Nan's jokes reflect more comprehensive fears: "green headscarf", "green hat" and "wearing a green hat" have all been used to refer to the husband whose wife cheated since Ming and Qing Dynasties. This kind of address is not only scattered in novels, but also one of the addresses of ordinary people. In addition, there are many jokes about "cuckolding".

Contemporary scholars chris powell and Steve Linstead pointed out in Humor-Resistance and Control in Society that the real meaning of many jokes lies in reflecting fear, thus strengthening and reshaping the moral boundary and achieving the goal of social control. According to their theory, perhaps we can think that there are many jokes about "cuckolding" in China society, which reflects the phobia of having sex with his wife. Therefore, such jokes have the functions of social vigilance and social control. So the name "green headscarf" should have originated from the Ming Dynasty. Musicians in the Ming Dynasty were a lowly profession, and it was stipulated that only green headscarves could be worn, so "green headscarves" became a symbol of lowly prostitutes.
