Later, Zhu Yuanzhang defected to the Red Scarf Army, became emperor, and tasted delicious food all over the world. Suddenly one day he was ill and couldn't eat anything, so he remembered the "pearl jade white jade soup" he had when he was begging in his hometown and immediately ordered the chef to cook it for him. The chef had no choice but to mix pearls, jadeite and white jade to make soup. After Zhu Yuanzhang tasted it, he felt that it was not right at all. In a rage, he killed the cook and found a cook from his hometown to do it. The cook is very clever. He thought to himself, since the emperor is not interested in the real "pearl jade white jade soup", I might as well take a chance with an imitation. So he replaced the pearls with ichthyosaurs, sliced red bell peppers with flying (flying is ruby), spinach with Cui (Cui is emerald), tofu with white jade, and fish bone soup. After offering this dish, Zhu Yuanzhang felt delicious as soon as he ate it, just like the old woman gave it to him, so he ordered it to be given to the chef. After the chef was rewarded, he went home sick and passed this dish that Zhu Yuanzhang liked to eat on to Fengyang's father.
