Diao Chan Tofu This tofu dish is named after Diao Chan, a beauty from the Three Kingdoms. It is said that the popular colloquialism "eating tofu" among Hong Kong people comes from this allusion. This dish is also known as "Han Palace Cangjiao" or "Loach Drilled Tofu", which is intended to use the whiteness of the tofu to describe Diao Chan's purity, and the loach's drilling to allude to Dong Zhuo's cunning. The loach struggled in the hot soup and had nowhere to hide. Even if it was put into cold tofu, it still couldn't escape the fate of being cooked. After being cooked, the tofu is white, delicious and spicy, and the soup is mellow. While tasting, people are reminded of the story of Wang Yun offering Diao Chan and using a beauty trick to eliminate the traitor Dong Zhuo, which naturally adds cultural content to the food.
