Lu Xun said: "People who eat crabs for the first time are admirable. They are not warriors. Who dares to eat? " Crabs are terrible in shape and have to pinch people. People who start eating crabs really need some courage. But it can be said with certainty that the Chinese nation was the first to know how to eat crabs. There is "crab Xu" in Zhou Li, which is said to be a kind of crab sauce. It can be seen that as early as more than two thousand years ago, crabs appeared as food at the banquets of our ancestors. The Book of Qi Yaomin written by Jia Sixie in the Northern Wei Dynasty introduced the method of raising crabs and improved the method of eating crabs. Later, Lu Guimeng's The Story of the Crab, Fu's The Book of the Crab and Gao's A Brief Introduction to the Crab were all monographs on crabs, and China people knew more about crabs. However, eating crabs, as a leisurely cultural enjoyment, began in Wei and Jin Dynasties. According to "Shi Shuo Ren Xinyu Sheng", Jin (character) is addicted to alcohol, saying, "Holding a glass in his right hand and a crab claw in his left hand, he will shoot floating wine boats all his life." This outlook on life and diet has influenced many people. Since then, people regard eating crabs, drinking, enjoying chrysanthemums and writing poems as romantic things in autumn, and gradually develop into gathering relatives and friends to eat crabs, which is also a "crab feast".
