Both soybean milk and milk can be used, both of which are rich in protein. Soymilk is plant protein and milk is animal protein. But quite a few people in Asia are lactose intolerant, so they can't drink milk. Soymilk is also a very good choice, and it is also very convenient now. For example, Yonghe Soymilk also has tetra pak Soymilk, which can be drunk directly after health. Soymilk originated in China, and it is said that it was invented by Liu An, King of Huainan in the Western Han Dynasty, more than 900 years ago. When Liu An was making an alchemy in Bagongshan, Huainan, he occasionally put gypsum into soybean milk, which became tofu after chemical changes. Tofu came out from then on, and many ancient books recorded it.
The freshly ground soybean milk was made by Liu An, King of Huainan in the Western Han Dynasty, more than 1900 years ago, so it has a history of nearly 2000 years. So how did you come up with the idea of making freshly ground soybean milk? That's because: According to legend, Liu An is a dutiful son. During his mother's illness, Liu An used soaked soybeans to grind soybean milk for his mother to drink every day. Liu's illness soon recovered. Since then, soybean milk has gradually become popular among the people. The freshly ground soybean milk was invented by China and made in China, and China has a very authoritative right to hold it.
