Jiaozi is in memory of Qu Yuan. Mom?

jiaozi was invented by Zhang Zhongjing to treat typhoid fever.

According to legend, Zhang Zhongjing, a "medical sage", was the prefect of Changsha at the end of the Eastern Han Dynasty, and then resigned and returned to his hometown. Just in time for the winter solstice, he saw that the people in Nanyang were hungry and cold, and their ears were frostbitten. At that time, typhoid fever was prevalent and many people died. Zhang Zhongjing summed up the clinical practice in the Han Dynasty for more than 3 years, so he set up a medical shed in the local area, set up a cauldron, boiled mutton, peppers and medicinal materials for removing cold and warming, made them into ear shapes with flour bags, and gave them to the poor with soup and food after cooking. The common people ate from the winter solstice to New Year's Eve, resisted typhoid fever and cured their frozen ears. From then on, villagers and later generations imitated it and called it "dumpling ears" or "jiaozi", and some places called it "flat food" or "instant noodle dumplings". After gradually forming a custom, it is absolutely impossible to eat without jiaozi on holidays. More than 1,4 years of history has made jiaozi take root in the minds of ordinary people. Jiaozi gradually became the spokesman of China's diet.
