Because in the Tang Dynasty, it was Li who ruined the world, and because Li was a national surname, it was forbidden to eat carp in the Tang Dynasty, mainly because it was taboo. If you catch carp, you must let it go. If you dare to sell carp, you have to hit 60 boards. The law belongs to the law, and people still eat carp For example, in Wang Wei's Song of Luoyang Girls, it is said that it is carp that eats sashimi. A man named Quan Deyu's "Appreciating East Zhejiang Ginseng Thirty-two" also talked about stewed carp.

Bai Juyi also has a poem on Jiangzhou Road, which contains a poem about drinking crucian carp soup. Bai Juyi was still guilty at that time. He has just been sent to Jiangzhou. How can he know the law and break the law? Therefore, this provision of the Tang Dynasty can only be expressed on the surface of the article, and no one takes it seriously.

According to this taboo, people in the Tang Dynasty could not eat carp, so people in the Ming Dynasty could not eat pork. At this point, Zhu Yuanzhang is still relatively open, and he even wrote couplets to the butcher. However, during the period of Zheng De, Ming Wuzong issued an order prohibiting eating pork.

He said that not only was my surname Zhu, but I was also a pig. In addition, if I eat too much pork, it is easy to grow pustules, so I suggest you not to eat it. Now, we should kill the pig quickly. If we commit crimes on purpose, we will have to send them to the army. The imperial edict shocked the whole country. /kloc-within 0/0 and a half days, all the pigs in the country were slaughtered and sold, so that the price of pork plummeted and the pigs were buried on the spot if they could not be sold.

A few months later, the sacrifice must be made with pork. If there is no pork, it must be replaced by mutton, which is also not in line with etiquette. In desperation, Ming Wuzong had to approve that pork could be secretly used for sacrifice, so this order also existed in name only.
