Red-oiled onion-skinned egg tofu

It has been rumored that Liu Bei had borrowed his troops from Dong Wu, and had taken his men to Sichuan, leaving Guan Yu town to guard Jingzhou. This summer, it was a hot summer, and the soldiers practice martial arts against the sun, sweaty and sweaty. For a long period of time, many of the students had internal fires, dung knots, yellow and dry tongues. Guan Yu is anxious. Guan Yu was alone in the library one day thinking, without realizing that the sun would rise three times, and that he would eat from the bottom, with the same soybeans. He immediately thought of tofu, and he said in his medical book that the plaster is cold, but it's hot. Guan Yu told Sgt. Sgt. Bean, boiled, put some plaster in his hand. The soldiers had to eat only with salt, which, by chance, was like a potion of good medicine, and the soldiers had eaten it, and they were slowly getting better. Later, a number of army sergeants mixed their home-grown eggs into fresh tofu and, together with spices, not only tasted good, but also thermally detoxified, making it a popular dish。
