Why do old Beijingers like drinking? Where is the bean juice? ?

Speaking of bean juice, we all know that it is one of the special cuisines in Beijing, because it is so sour that it is difficult for ordinary people to adapt.

When I was at school, I heard my classmates in Beijing say that soybean milk is very nutritious, and then I looked up the information. The sour taste of soybean milk is mainly due to lactic acid. Besides water, protein, various amino acids and trace elements such as potassium, sodium, calcium, magnesium, iron, copper, zinc and manganese are the main components of soybean juice, and the nutrition is really very rich.

Of course, bean juice can become a must in old Beijing because it may come from the flag bearer, and the Eight Banners even called bean juice "the core historical food of life". There is a joke: One day, the flag bearers in the military camp outside Qihuamen (Chaoyangmen) gathered in the street and wept bitterly. Passers-by asked them, the more people cry, the more painful they are, and said, "If the bean juice workshop is closed, wouldn't it kill them?" Although this is just a joke, we can also see the origin of bean juice and the Eight Banners.

Although the taste of bean juice is more exciting, it is loved by old Beijingers all year round, and even the locals gradually adapt to its unique taste. In a bean juice shop, I met an old man who said he drank bean juice every day.
