Most snacks in old Beijing originate from the daily life of ordinary people. However, with the decrease of hutongs, people who like old Beijing snacks are decreasing, among which bean juice and inby are the most famous. This kind of collocation is often eaten at breakfast, which has always been the least popular among outsiders, but in the eyes of old Beijingers, it is delicious. Although bean juice is famous, it is often humorously called "brushing pot water".

Another snack also originated from the folk, and it is also a typical snack, that is fried liver. As a common delicacy now, it is also loved by Chinese and foreign tourists. According to legend, the vice president of the United States specially tasted it before his visit. This snack can be eaten in many places at present, but it is generally recognized as Yao Ji fried liver shop next to Gulou Street. Many old Beijingers like to order a bowl of fried liver with a plate of steamed buns for brunch.

The snack introduced below is called fried enema, which is generally not a staple food. It's just to fill people's stomachs and relieve their hunger. In old Beijing, there are two kinds of enema. Now we all know that it is a popular way to fry it crisp and then serve it with a bowl of mixed garlic juice, which tastes good. However, this snack must be eaten while it is hot. If it cools down, it will greatly affect the taste.

There is also a method of making enema, which only old Beijingers will mention. It is said that a layer of sausage skin is prepared, and chop suey soup is poured into it to heat it, and then a knot is tied at the other end of the sausage. After cooling, it can be cut and tasted. This dish is really rare in Beijing today. It is said that it is the skill of a stall owner on Di 'anmen Street.
