According to legend, at the end of the Qing Dynasty, an adult in Chengdu Prefecture made a fuss, suffered from malaria, and his food was tasteless. It happened that one of his touts went to visit his cousin's house in Tangchang Township, Dayi, and when he came back, he put her homemade bean curd in a small oil basket and gave it to Taiwan Province. This fragrant and delicious tofu aroused the appetite of adults in Taiwan Province and ate a lot. After eating for two days, my mouth is not bitter, my appetite is open, and my illness is much better. Taiwan Province adults ask tout, this tofu how so delicious? Favourite told him that this kind of tofu is different. First, press the tofu very dry, then sprinkle with salt to dry or air dry, then put it on the kang, mix with aged watercress, sea pepper and vegetable oil in the mirror jar, and seal it for one year before opening and taking it out. Taiwan Province adults want to eat this kind of tofu milk again, so let touts invite his wife Aunt Tan to yamen to make tofu milk. When Aunt Tan came to Chengdu, the tofu made was always not as delicious as the tofu returned by Tang Chang. Taiwan adults asked why, and Aunt Tan thought it might be that the water pushing tofu was different. There is a well in her yard. The water is clear and sweet, and there seems to be a little chrysanthemum fragrance. The ground tofu is thin, tender and soft. Taiwan Province thought so, so he gave Aunt Tan some money, told her to go home and make bean curd, and then sent it over. In the future, every time Taiwan Province invites guests to dinner, he will always add a dish of bean curd in addition to all kinds of meat dishes, and the guests will say yes after eating. In the future, more and more people will go to Tan's mother's house to buy tofu milk.
