1 Different places of origin: Yuntui is produced in Yunnan, which is one of the local specialties in Xuanwei City, Yunnan Province. Because of its origin, it is called Yuntui, while there are many places of origin for ham, such as Jinhua ham in Zhejiang and Gao ham in Nantong, Jiangsu. 2. Different pig breeds: the pig legs selected by Yuntui are black running pigs from Yunnan, which are free-range, and their characteristics are pure natural breeding, while the pig breeds used by other hams are different. For example, Jinhua ham is black pigs from Jiangsu and Zhejiang provinces, and Gao ham is mostly local Dongchuan pigs. 3. Different types: Yuntui only refers to ham marinated with pig hind legs, while other kinds of marinated ham can also be called ham, such as lamb leg, ox leg, chicken leg and so on. 4, the taste is different: the method of making cloud legs is smoked, so you can obviously feel the smell of smoke when eating, but other kinds of hams are made in different ways, such as pickled, sun-baked, fermented and so on.
