The origin of stinky tofu:Legend has it that in the eighth year of the Kangxi period, there was an Anhui scholar, Wang Zhihe, who went to Beijing to take the examination, and his name was Sun Shan. At this time all the travel expenses were spent, he had to stay in Beijing to participate in the next examination. When he was a child, he made bean curd. In order to make a living, he sold it at the then Anhui Guild Hall. Once in the middle of summer, there was a lot of tofu left to sell. When he saw it, he was worried. It would be a pity if it was dumped. At that moment, he suddenly remembered that his old family used them to make tofu brain, but he forgot how to do it. Just cut the tofu into small pieces as much as possible, add salt and pepper, and seal it in a jar. After a long time, Wang Zhihe remembered and hurriedly opened the jar, the stench came out and the tofu turned green. He tasted it curiously, but it tasted good. Thus, Wang Zhihe's stinky tofu became famous.
