What does Sun Simiao mean when he says that goose, dog and snake head can't eat?

Sun Simiao said that geese, dogs and carp are not allowed to eat.

Sun Zhenren's health song says that geese are orderly and dogs are righteous, and herring knows the northern ceremony. People are rude and righteous, and the gods of heaven and earth don't like it.

Birds in the sky, animals on the ground and fish in the water are all spiritual. Wild geese maintain order, dogs are affectionate, and snake heads know manners, but human beings are rude and heartless, so Taoism has formed the tradition of "three dislikes".

Major achievements

Sun Simiao is not only good at internal medicine, but also good at gynecology, pediatrics, surgery and five senses. For the first time, Chinese medicine advocates the establishment of a separate department for the treatment of women and children. In his works, he first discussed women's and children's medicine, explaining that it is "the meaning of respecting the roots."

He attaches great importance to maternal and child health care, and has written three volumes of Women's Prescription and two volumes of Children's Prescription, ranking first in Thousands of Women. Under his influence, medical workers in later generations generally paid attention to the research on the treatment technology of gynecological and pediatric diseases.
