Cantonese cuisine, also called "Cantonese cuisine", is one of the four major cuisines in China, which was recorded in the Western Han Dynasty. Under the influence of Yangcheng Imperial Chef, Bao Zongshi developed rapidly in Ming and Qing Dynasties. In the 20th century, as foreign communicators absorbed some skills of western food, Cantonese cuisine was introduced to all parts of the world, and there were thousands of Cantonese restaurants in new york alone.

In the meantime, there are good and ugly games. There are turtles in the mountains, which are cooked by pigs, and the lips of sturgeon are alive, which is called the soul of fish. This is also precious. When you meet a snake, you must catch it, no matter how long it is; Catching rats, big or small. Bats are hateful, clams are terrible, locusts are microscopic, and they are eaten as soon as they are taken; The poison of the hive, the filth of the hemp insect, is cooked and eaten; The eggs of locusts and the wings of shrimps are cooked and eaten.

When Han Yu was relegated to Chaozhou in the Tang Dynasty, he was greatly surprised when he saw that the local people were addicted to dozens of foreign objects such as turtles, snakes, octopus and frogs. He was so scared that he was "ashamed and smelly, and his face was sweaty." Today, abalone, ginseng, wings, belly and delicacies are still unique delicacies and medicinal diets in Cantonese cuisine.
