In ancient times, some emperors had a certain complex with hot pot. Yuan Shizu Kublai liked to eat hot pot. One winter, the army was about to open suddenly, and he was hungry, and he must eat mutton. The clever chef cut the mutton into thin slices and put them Put it in a pot of boiling water and blanch it, add seasonings, green onion and other things. After eating, Kublai is full of praise. Later, he did the emperor still not forget this dish, and gave it the name "Shubu Lamb". According to legend, when Ming Dynasty writer Yang Shen accompanied his father Yang Qianhe when he was young, he went to the banquet set by Emperor Hongzhi in the imperial garden. At the banquet, there was a hot pot of mutton and charcoal was burning in the fire. Emperor Hongzhi used this to get a couplet. Shanglian said: "The charcoal is red and ash is like snow." At this time, the young Yang Shen quietly chanted the bottom line to his father: "The yellow rice and white rice are like frost." His father read his son's dialogue to the emperor, and the emperor Longyan Joye immediately enjoyed a glass of royal wine. Emperor Qianlong of the Qing Dynasty also became addicted to eating hot pot. He traveled to the south of the Yangtze River many times, and he prepared hot pot wherever he went. According to legend, in the first month of the first year of Jiaqing, he held a "thousand old banquet" in the palace. There were more than 1,550 hot pots in total and more than 5,000 invited tasters, making it the largest hot pot feast in history.
