Therefore, there are probably two reasons for the taboo of "dog meat is not on the table". First, Buddhism flourished in the Tang and Song Dynasties. Although Buddhism at that time had to eat meat, it believed that dog meat was extremely filthy and should not be eaten. Therefore, in "Water Margin", Lu disobeyed the precepts, ate dog meat and drank wine, then got as drunk as a fiddler and ran into the gate. Another reason, which is also the most important reason, is the dog. A minister named Fan flattered him and said: Your Majesty is a dog, but someone in Kyoto actually kills dogs for a living. This is disrespectful to your Majesty and should be banned. Although Song Huizong writes well and draws well, he is a complete idiot at heart. He immediately decreed that it was forbidden for the people to keep dogs for food, let alone kill them for sale. In order to ensure that this ban is implemented, he also specially allocated 20,000 yuan to encourage violators to report.

More than 20 years later, when the Northern Song Dynasty perished, it was no longer illegal to kill dogs to eat meat, but the number of people who ate dog meat had been greatly reduced, and "dog meat was not served on the table" became a deep-rooted taboo. Now besides Koreans, only Guangdong, Guangxi and Guizhou are addicted to dog meat. In the cold winter in the Central Plains, only dog meat is forbidden for tonic, not as regular meat. Even in places where dog meat is eaten, there is often a lot of attention. For example, when cooking dog meat, the stove is moved outdoors, and eating dog meat can only be done in the open air-dog meat can not only be served, but also can not enter the room.
