According to legend, Zhu Yuanzhang was poor when he was young and never had enough to eat. /Kloc-When he was 0/7 years old, he was homeless because his parents died of the plague. In order to have a meal, he was forced to become a monk in his hometown Huang Jue Temple. However, there was a famine in his hometown soon, and the incense in the temple was neglected, so he had to go out for alms. In the meantime, he went through many vicissitudes, and often didn't eat a bite of rice all day. On one occasion, he got nothing for three days in a row. Hungry and dizzy, he fainted in the street. Later, she was rescued by a passing old woman and brought home. He put the only piece of tofu at home with a handful of spinach and red roots and green leaves, poured a bowl of leftover rice and cooked it for Zhu Yuanzhang. After eating, Zhu Yuanzhang was in good spirits and asked the old woman what she had just eaten. The old woman took pleasure in suffering and joked that it was called "Pearl Jade White Jade Soup".

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.
