Huainan beef soup, one of the representatives of Anhui cuisine, is a well-known snack in Jiangsu, Henan, Shandong, Anhui and Shanghai.
There are two theories about the origin of Huainan beef soup: Zhao Kuangyin in the Song Dynasty and Liu'an, the king of Huainan.
During the Qianlong period of the Qing Dynasty (1736-1796), Zhang Zheng, a master of Hanlin and a native of Huainan, deeply studied herbs and was good at food. After returning home, he passed on the secret recipe of the Qing Palace to future generations.
