As early as the Qing dynasty, there was a poem praising enema: "The red powder in enema is fried for a while, and the spicy garlic and salty juice are delicious", which is enough to see the love of Beijingers for enema. Fengnian enema on Longfu Temple Street is an old-fashioned franchise store, but now there are not many shops specializing in some traditional snacks. The raw material of Fengnian enema is sweet potato powder. After being fried by special boiling, it is tender in the outside and poured with garlic juice when eating, which is very delicious. With a small pickle and a millet porridge, it moistens it. Although the store of this good harvest enema on Longfu Temple Street is not large, it is extremely famous. Here is mainly engaged in enema, which has been opened for more than 50 years and has become one of the time-honored snack bars in Beijing.
