The lean meat here refers to lean pork, of course, while the "tender chicken" refers to the broiler, that is, the cockerel. Because the heroes in Water Margin like to be single, they are not close to women, leaving excess energy, drinking and eating meat, making the gun stick.
When the heroes of Water Margin drink, besides eating beef, they also like to eat chicken, which is not an accidental phenomenon, but reflects the folk worship of the boy.
In Taoist culture, a boy refers to a boy who has not yet grown up and has no sexual life. These boys are pure in yang, and the boy's kung fu is considered to be the purest. When you grow up, because you have sex and lose your vitality, your exploits will disappear.
People attach great importance to "golden couple" and "boy and girl". On the surface, it seems to mean equality between men and women. In fact, "boy" refers to the little boy, and the boy chicken refers to the rooster, excluding the little hen.
In rural areas of Zhejiang, there are still many places where the custom of eating the urine of a boy is spread. That is, in spring, the people collect the urine of a little boy and cook it with the eggs until the urine of the boy is boiled dry. People think that such eggs are a great tonic.
Later, "Broiler Chicken" was translated into "SpringChicken". In fact, this translation is also wrong. Because the spring chicken will be mistaken for the spring chicken that is in heat in spring, and the original intention of the broiler is not related to sex, so this translation is related to sex.
