According to historical records such as Hanshu and Jinshu, "It was the eighth year of the Emperor's reign (239 BC), when the river fish was big, Liu Xiang thought it was evil to be near the fish"; "In May of the fourth year of Jiaping, the king of Wei Qi (AD 252), there were fish on the armory house, and this fish was evil." The meaning of the word "fish evil" includes both good luck and bad luck. The ancients attached some abnormal phenomena of fish to some things, which can be said to add a mysterious color to the fish. ? As a food custom, fish is regarded as a mascot, such as "Mingtai Fish" eaten by Korean compatriots in Northeast China every time they go to Tomb-Sweeping Day. "Mingtai" was originally the name of an old North Korean farmer. It is said that there was a severe drought in the northeast coastal area. An old farmer named Park Mingtai led the villagers to catch a kind of marine fish to satisfy their hunger and spend the famine. The fish was black and one foot long, and it could be stored after being marinated in salt water and dried. There is a fish dish "Yuanyang Fish" in Shandong cuisine, which is steamed with white mandarin fish and red red fish. It is salty, fragrant, fresh, red and white, and attractive in color. This dish is a famous dish of Confucius in Qufu. It is often used as the main course of wedding banquets, symbolizing the kindness and love of newlyweds and never parting. ? There are also many popular stories about fish in southern China. Suzhou embroidery "Suzhou embroidery" in Jiangsu Province is popular with a fish pattern "Fish Playing Lotus", which is the favorite auspicious picture for women to embroider for their husbands or lovers. Rural families in northern Jiangsu hang a fish on the scale hook every Lunar New Year's Eve, and the local dialects "scale", "leftover", "fish" and "surplus" are homophonic; "There is fish (surplus) in the scale, and there is fish every year", which has become a popular saying.

According to legend, at the end of the Eastern Han Dynasty, Zhang Zhongjing, a "medical sage", was the prefect of Changsha, and then resigned and returned to his hometown. Just in time for the winter solstice, he saw that the people in Nanyang were hungry and cold, and their ears were frostbitten. At that time, typhoid fever was prevalent and many people died. Zhang Zhongjing summed up the clinical practice in the Han Dynasty for more than 3 years, so he set up a medical shed in the local area, set up a cauldron, boiled mutton, peppers and medicinal materials for removing cold and warming, made them into ear shapes with flour bags, and gave them to the poor with soup and food after cooking. The common people ate from the winter solstice to New Year's Eve, resisted typhoid fever and cured their frozen ears. From then on, villagers and later generations imitated it and called it "dumpling ears" or "jiaozi", and some places called it "flat food" or "instant noodle dumplings". After gradually forming a custom, it is absolutely impossible to eat without jiaozi on holidays. More than 1,4 years of history has made jiaozi take root in the minds of ordinary people. Jiaozi gradually became the spokesman of China's diet.

The first person to eat crabs

It is said that thousands of years ago, there was a fierce beetle with eight legs and two claws in the river and lake. Not only does it steal rice, but it also hurts people with claws, so it is called "human-trapping worm". Later, Dayu went to the south of the Yangtze River to control the water, and sent a strong man, PLO, to supervise the work, which seriously hindered the project. The PLO figured out a way to dig a trench around the city and fill it with boiling water. People and insects came over, and they fell into the ditch and burned to death. The scalded insect was flushed and gave off an attractive and delicious fragrance. The plo broke the shell curiously, and the smell was stronger. I got the nerve to take a bite, but the taste is fresh and delicious, which is better than anything else, so the feared pests have become a household name. In order to thank PLO, who dared to be the first in the world, we added the word "worm" under the word "Xie", which means PLO conquered the worm and was the first crab eater in the world.

allusion to "eating tofu": In the old days, tofu shops were mostly husband-and-wife shops. The proprietress was tender and white because she ate more tofu, and she was delicious. At the same time, in order to attract customers, she did something coquettish, which led men to flirt with the proprietress in the name of "eating tofu". So, the jealous wives were dissatisfied and said, "Did you eat tofu again today?" To reprimand her husband. Later, "eating tofu" became synonymous with men and frivolous women.
