Bean juice is a unique traditional snack in old Beijing with a history of 300 years. The standard of bean juice: a bowl of bean juice, two inby and a dish of shredded mustard. The correct way to eat it is as follows:

1, take a bite of inby and put it in your mouth, which is burnt.

2. Take a sip of bean juice and let the warm and smooth liquid soak inby. The original stimulating taste will be much softer.

3. Finally, take a bite of salty shredded mustard to enrich the taste and relieve boredom. Chew it and swallow it, and you will feel a little sweet.
