It is said that Zhu Yuanzhang was once hungry when a monk begged, and was saved by a peasant woman. What the peasant woman cooked for him was tofu, which he thought was the best thing in the world after eating it. Later, when she became emperor, she let the peasant woman do it. But I can't make the original flavor. Finally, people around him told him that he felt particularly delicious because he was hungry at that time. Later, he ate this tofu dish, mainly to remember that painful experience. Later emperors would put this dish on the court menu whether they ate it or not.
