The trend of eating donkey meat has also sprung up in Guangdong, Guangxi, Shaanxi, Beijing, Tianjin, Hebei, Shandong and other places, which shows that there is great potential for the development of raising donkeys. In addition, the donkey's natural tolerance to harsh environmental living conditions is the most prominent of all livestock.
