During the Song Dynasty from the Western Zhou Dynasty to Su Dongpo, no matter who was rich and powerful, they didn't like to eat pork. Since Su Shi, a famous poet and gourmet, praised the delicacy of pork and studied Dongpo pork and Dongpo elbow, pork dishes have become popular among the rich and powerful.

In addition, we are a big food country, and there is a saying that medicine and food are homologous. Traditional Chinese medicine studies the medicinal properties and traditions of food. In the eyes of ancient physicians, pork was really criticized. Every kind of meat has supplements, but pork doesn't help. Pork can seal blood vessels, weaken bones and muscles, and make people weak. Sun Simiao, the drug king, even said that if people eat pork for a long time, their children and sperm will be reduced and they will suffer from diseases.

I think these reasons are very reasonable, until one time I saw an unearthed cultural relic of the Han Dynasty, and then I suddenly thought of a simple and rude answer: Why didn't the ancients like to eat pork? This cultural relic seems to be a ceramic residence in the Han Dynasty. It can be clearly seen from this cultural relic that the toilets of ancient people were in pigsty, and people took a shit and pigs came to eat it. The wisdom of ancient people to make the best use of things is also commendable, but it is inevitable that they will feel upset in the stomach when used here, which may be the biggest reason why ancient people don't like to eat pork.
