The Loach Drilling Tofu, also called "Diaochan Tofu", is a popular metaphor for the cunning Dong Zhuo. The loach was so anxious to hide in the hot soup that it drilled into the cold bean curd, but the result was that it could not escape the fate of being cooked. This is just like Wang Yun's offering of Diaochan, a beauty plan. The origin of this allusion is no longer known.
"Loach drill tofu" is said to have originated in Henan Zhoukou circle Temple Street, said a fisherman named Xing Wenming, to catch fish and shrimp for a living, he was fishing, but often caught some loach, often the larger loach sold, the rest of the small unattended, each time, had to bring home to their own cooking. Once, he turned the pattern for the taste of spice, simply put the small loach at home in a water basin to spit out the mud, and from the street to buy back some tofu and onions, ginger and other seasoning, because the loach is small and not easy to pick up, then put the fish in the pot with the lid on the pot with ginger and garlic with tofu and cook. To be cooked and uncovered to see, found that the small loach are drilled into the tofu to go, only the tail to stay outside. This method will soon be spread in the local folk, that is, the name of the "loach drill tofu".
