Anyang is located in the Central Plains, and most surrounding counties are rich in sweet potatoes. There are many sweet potatoes, and hardworking and clever locals make sweet potatoes into starch, which is used to make vermicelli and vermicelli. Legend has it that a long time ago, there was a boss who sold vermicelli and vermicelli. When the vermicelli is sold too much, naturally there are some broken vermicelli, so he sells it to the restaurant cheaply. At that time, a clever chef had a brainwave after receiving these fans. He put the vermicelli in the boiling water pot and boiled it until it was soft. After taking it out, he added chopped green onion, Jiang Mo, minced garlic, salt and shrimp skin, then added sweet potato starch, stirred it evenly, put it in a bowl, and put it in a steamer to steam it into skin residue. So far, it has become an Anyang-style snack, one of the "three treasures" in Anyang.
