On the seventieth birthday of Emperor Qianlong, Emperor Qianlong chose to hold a birthday banquet for himself in Changchun Garden, and invited ministers above the court to hold a banquet. But when these ministers arrived from their home, the food was already cold. So after this birthday party, these ministers all got a slight illness, their stomachs were uncomfortable, and they began to have diarrhea symptoms. So Emperor Qianlong hoped to solve this problem on his next birthday.
At this time, Emperor Qianlong's little Shenyang came up with an idea. When Xiao Shenyang sees people eating during a folk tour, he sometimes chooses to take a copper pot, put some children's dishes and boil water in it. Therefore, when Emperor Qianlong was worried about this matter, Xiao Shenyang put forward his own plan. Tell Emperor Qianlong that we can cook the food well, but don't cook it well. Put them on the table. Put a pot on the table. When the ministers arrived, the food was still fresh. This will not affect the taste of the food, nor will it cause these ministers to feel uncomfortable after eating.
By the time of Qianlong's eightieth birthday, Emperor Qianlong held his own birthday banquet in this way. When these ministers attended Emperor Qianlong's birthday banquet again, they found that the food this time was very cold, all hot and delicious, and they could rinse it if they wanted. After that, this delicious food gradually evolved into the hot pot we eat on the table today.
