Bayi, a famous Ningxiang native in the Southern Song Dynasty, also had an anecdote with Daodouhua. According to records, "in the city hall of the Song Dynasty, there was a business specializing in knife tofu pudding. In the 12th year of cherishing spring in Song Xiaozong, the Yi people changed the word "mountain vegetarian", and palace examination took the lead. Xiaozong called him to the convenience hall, asked about the scenery of Chu, and praised the bean curd made by Yicheng women for its excellent shape, color, taste and art. After the formal ceremony, he soaked the bean curd into a filial son with a knife soaked in honey, which was called joy. Therefore, Ningxiang Daodouhua is famous in Beijing. " According to legend, Daodouhua has been listed as a "tribute" since then. "Ningxiang County Records of the Republic of China" contains: "There are knife tofu, orchid slices, bamboo branches and flower baskets for family food, which are soaked in sugar and dyed red, so they are sweet."
