It is named by the country as the "Hometown of Donkey-hide Jiao in China". The donkey-hide gelatin produced has a history of more than 2,500 years and has " It is known as "Gongjiao". Dong'e's donkey-hide gelatin enjoys such a high reputation not only because of its authentic and traditional production techniques, but also because of its unique geographical location and natural conditions. The town is located more than a hundred miles southwest of Jinan, to the east is Mount Tai, the leader of the Five Mountains, and a world-famous historical and cultural city, and to the southwest is Shuibo Liangshan Mountain. Three miles southwest of it is Shi'er Mountain, with lush grass and abundant forests, and hundreds of Chinese herbal medicines and donkey food. The skin is strong and fat, the coat is black and shiny, and the skin is particularly suitable for making glue; the Langxi River, which is adjacent to the west and gathers the water of Jiuquan, runs through the town, and is connected to Hongfan Jiuquan. The specific gravity and hardness are small, and it can be used to soak the skin and boil the glue to reduce the number of raw materials. Contamination, ash content is easy to control and the storage time is long. Dong'e Town has such unique natural conditions, so the production of donkey-hide gelatin has been passed down from generation to generation and has been prosperous for a long time. The literature records: "Choose a pure black healthy donkey, feed it with grass from Shi'er Mountain, drink water from Langxi River, kill it in winter, take the skin, put it in a gold pot, add Langxi River water, put the mulberry wood on a slow fire, stir it with a silver shovel, for three days and nights..."
