Liangfen is a special kind of food that comes from China. It is made from a type of bean called green beans. The green beans are first soaked in water for a long time, and then they are ground up into a paste. This paste is then cooked and mixed with other ingredients like starch to help it turn into a jelly-like substance.
Once the liangfen has hardened, it is cut into small pieces and served with a sauce made from soy sauce, vinegar, and chili oil. Sometimes people also like to add other flavors like garlic or sesame oil to the sauce.
Liangfen is often eaten as a snack or a side dish and it has a unique texture that is both chewy and soft. Some people describe it as being like jello or a gummy candy. It is a popular street food in China and is known for its refreshing taste on hot summer days.
