Zhu Yuanzhang asked for a bowl of Yong Tofu at the Huang Family Restaurant in Fengyang City. After eating it, he felt it was very delicious. From then on, he often went to this restaurant to beg for Yong Tau Foo. Later, he put on a dragon robe and became the emperor, so he ordered the chef from the Huang Family Restaurant in Fengyang City to be summoned into the palace to cook "Fengyang Yongdoufu" specially for him, and became the chef in his imperial dining room. From then on, this dish became worth hundreds of times and became a famous dish at the Ming Dynasty palace banquets.
