It is really unclear what kind of mutton boiled buns the subject refers to. As another respondent said, "it should be three fresh boiled buns", most of which are opened by Han people.
Pot mutton is also mainly run by Han people, and most of them are better than those of Hui people. The famous pots in Chengcheng, Pucheng and Dali are quite famous. In recent years, Heyang has been striving for the name of the authentic birthplace of pots. The mutton in the basin is mainly soup, so the first thing you see when you serve it is a big bowl of soup. When fishing for the bottom of the bowl, you will find a lot of large pieces of mutton. Steamed buns are typical crescent cakes. They are hollow and can be eaten in water or with vegetables.
