Female compatriots all know that Ejiao is the best tonic for women, which can replenish blood and qi and enhance immunity. In recent years, Ejiao, like gold and real estate, has been rising in price. \x0d\ In earlier years, the price of Ejiao was one catty in 80 yuan. At that time, people's living standards were low, and food and clothing were enough, not to mention health care. Now people's living standards are high, and they have begun to keep in good health. In particular, women know how to maintain, and the demand for Ejiao has greatly increased, which is one reason for the price increase of Ejiao. But there are more important reasons: \ x0d \ x0d \ Donkeys-viviparous mammals, only give birth to one child at a time, unlike pigs. Donkeys are not like pigs. They can be promoted by hormones in a few months and grow into adult donkeys. At least a year or two. However, the demand of people far exceeds the production speed of donkeys, and the demand exceeds the supply, so the price of Ejiao naturally rises linearly. \x0d\ Now the whole donkey skin costs at least 30,000 yuan per ton. The cost per kilogram of boiled donkey skin is nearly 100 yuan, which is not counting the cost of technology, labor, packaging and transportation. Therefore, Ejiao, which is too cheap, is doubtful and may be fake.
