The mutton bread in soup evolved from the ancient mutton soup.

The meat paomo, also known as mutton pao, was called "mutton soup" in ancient times, and it was delicious with Han flavor in Guanzhong, which originated from Gushi Town, Weinan City, Shaanxi Province. It is well-cooked, the ingredients are heavy and mellow, the rotten meat soup is thick, fat but not greasy, rich in nutrition, full of fragrance, attractive appetite and endless aftertaste after eating.

Su Shi, a famous poet in the Northern Song Dynasty, wrote a poem, "There is bear wax in the dragon, and mutton soup is the only thing that Qin cooks". Because it warms the stomach and resists hunger, it is always loved by Shaanxi people, and foreign guests come to Shaanxi to try it first to satisfy their appetite. Mutton bread in soup has become the "general representative" of Shaanxi famous food.
