According to legend, Zhang Zhongjing, a doctor in Nanyang, was originally a medical officer, and it was a snowy winter when he retired in his later years. He saw that the villagers in Nanyang were hungry and cold, and many people's ears were frozen. So he asked his disciples to set up a medicine shed in Guandong, Nanyang. They cooked mutton, peppers and some herbs for removing cold in a pot, fished them out and chopped them, kneaded them into ears with leather bags, and then put them down to cook them in a pot to make a soup for removing cold and correcting ears for the villagers to eat. After the villagers had eaten, their frozen ears were cured. Later, on the solstice in winter, people imitated this way of eating by pinching their ears, saying that eating jiaozi on the solstice in winter would not freeze people.
