The spread of spicy powder originated in the Three Kingdoms period. After three brothers, Liu Huangshu, Zhao Yun and Guan Yunchang, became sworn friends in Taoyuan, the host of Taoyuan chose the sweet and sour powder that the locals loved very much as the main food. In addition, they added pepper, pickled vegetables and scutellaria materials, and Liu Huangshu wanted to tell them that they could eat the ups and downs of life. After that, it was handed down, and it was introduced and improved by later generations to become a delicacy in contemporary society.
