Yongnian Crisp Fish is one of the Han snacks in Handan, Hebei Province, which belongs to Hebei cuisine. I don't know when it started. During the Republic of China, Yongnian crisp fish became a popular food in restaurants, which was in short supply. What people are most worried about when eating fish is that they are afraid that the fishbone will prick their throats. I don't know which master created a production method, even the largest fish bones can be crisp and rotten, but the fish shape is still intact and the fish tastes delicious. Fish bone is the substance with the most phosphorus and calcium. It was a pity to throw it away in vain in the past, but now it has become a delicious food for people to absorb, and its nutritional value is nothing more than that.
