Ejiao cake is a food made of Ejiao, black sesame, walnut kernel, crystal sugar and yellow wine. Li Zhoukao Gong Ji Gong Ren recorded: "Deer glue is blue and white, horse glue is red and white, cow glue is red, mouse glue is black and bait glue is yellow."

Zheng Xuan's note: "It means cooking with its skin or horns." As early as the Zhou Dynasty, rubber made of animal skins was studied and classified in detail. At that time, cowhide was not the first choice of raw materials, but donkey skin and deerskin were favored.

The origin of Ejiao is named after its earliest birth in Dong 'e. The earliest existing pharmacological monograph in China, Shennong Materia Medica, lists Ejiao as "top grade", and Li Shizhen's Compendium of Materia Medica in Ming Dynasty records: "Ejiao is the top grade. Hongjing said: I was born in East Afghanistan, so I was named Gillian. According to historical records, Li Shizhen was born in 15 18 and died in 1593.

There is also an ancient folk song circulating in Dong 'e, "Little black donkey, white belly, pink nose, pink eyes, pink hooves, grazing in Shier Mountain, drinking water from langxi River, taking three trips to Yongji Bridge, rolling in Weijiachang, slaughtering its skin in winter, and still needing yin and yang water to make glue." In the process of making glue, only by burning Sang Mu and chopping wood with a golden pot and silver shovel for 7749 days can the glue be made.
