According to legend, Empress Dowager Cixi likes jiaozi very much, but once jiaozi gets cold, she refuses to eat it, so the chef has to keep cooking hot jiaozi and throw away the cold jiaozi. One day, the Queen Mother went to the back garden to enjoy the flowers, smelled a fragrance floating outside the palace wall, and went out of the palace curiously, and saw someone cooking something similar to jiaozi, with golden skin. She tasted it and found it crispy and juicy, which was quite delicious. Later, I learned that jiaozi was discarded by the chef. Because the skins are cool and stick together, they are not easy to cook in water, so they are fried and eaten hot. There is another saying, however, that a Guangdong master accidentally ate fried dumplings in the north of China, and thought it was delicious, so he took it back to his hometown and improved it into today's fried dumplings.
