The origin of stinky tofu: According to legend, in the eighth year of Kangxi's reign, an Anhui scholar named Wang Zhihe went to Beijing to take the exam. His name was Sun Shan. At this time, all the travel expenses were spent, and he had to stay in Beijing to take the next exam. He made tofu when he was a kid. In order to make a living, he sold it at the Anhui Guild Hall at that time. One summer, there was a lot of tofu left to sell. When he saw it, he was worried. It would be a shame if it was dumped. At this time, he suddenly remembered that his hometown used them to make tofu puffs, but he forgot how to do it. Just cut the tofu into as small pieces as possible, add salt and pepper, and seal it in a jar. After a long time, Wang Zhihe remembered and quickly opened the jar. The stench came to his nostrils and the tofu turned green. He tasted it curiously, but it tasted good. As a result, Wang Zhihe’s stinky tofu became famous.
