In ancient times, Xian 'an people were very hospitable. A beggar invited Longtan's new in-laws to dinner, specially made a dish of Wuchang fish to entertain the distinguished guests, and repeatedly explained: there is no good food, only a side fish, please don't take it amiss. After the banquet broke up, Longtan's in-laws took Yaozui's in-laws to pay a return visit. Yaozui's in-laws readily agreed and set a date for the return visit. After Longtan's in-laws came home, they thought about it. I don't have any fish here. What should I do for them? I think it's best to use meat to receive my in-laws, but my family is poor and I don't even have the money to buy a bowl of meat. I only have enough money to buy half a bowl of pork belly. I can't help it! Had to use tofu, sweet potato powder, fried rice twisted together into balls, cooked and cut the meat, put a ball of meat in a bowl, and put a few pieces of lean meat on the surface to cover it. The food was ready, but before the in-laws came, he steamed the bowl of meat in a rice cooker. When the in-laws came, the host brought a bowl of tower-shaped meat to the table, only to see that the bowl of food was hot, delicious, golden and full of color, which was particularly attractive. After the in-laws tasted it, they were full of praise. This dish spread from mouth to mouth and spread from mouth to mouth. Over time, it became a famous dish for Xianan to entertain guests.
