According to folklore, Pearl Jade White Jade Soup originated from the Ming Emperor Zhu Yuanzhang. When Zhu Yuanzhang was young, he was very poor and never had enough to eat. He often didn't have 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 high 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". Therefore, based on this allusion, we basically restored the real practice in the play, and there was basically no innovation.
