Why do ducks look handsome?

Hello, this should start from the south. Prostitutes in the south are generally called chickens (in southern dialects, chickens are pronounced the same as prostitutes). Later, female sex workers were called chickens.

Male sex workers were called cowherd (a term introduced from Hong Kong, Macao and Taiwan) in the early days of reform and opening up. Later, people thought it didn't match the common name of prostitutes, so they simply used another most common poultry to describe it, and there was the saying of "duck". Therefore, the names of "chicken" and "duck" are widely circulated. Male sex workers are therefore called ducks.
