Dumplings are a traditional food loved by our people. Its preparation method is to first use flour to make thin and soft dumpling skins, then chop fresh meat, cabbage, etc., mix with condiments as fillings, wrap them up, and cook until the dumplings float to the surface. It is characterized by thin skin, tender filling, delicious taste, unique shape, and you will never tire of eating it. The original name of dumplings is "Jiao Er", which was first invented by Zhang Zhongjing, a Chinese medical sage. At the end of the Eastern Han Dynasty, disasters occurred in various places and many people suffered from diseases. There was a famous doctor in Nanyang named Zhang Ji, also known as Zhongjing. He studied medical books diligently since he was a child, learned from others' strengths, and became the founder of traditional Chinese medicine. Zhang Zhongjing not only had excellent medical skills and could cure all difficult and complicated diseases at his fingertips, but also had high medical ethics. He treated both poor and rich seriously and saved countless lives. When Zhang Zhongjing was an official in Changsha, he often cured diseases for the people. One year when the local plague was prevalent, he built a big pot at the yamen gate and gave up medicine to save people. He was deeply loved by the people of Changsha. After Zhang Zhongjing retired from Changsha and returned to his hometown, he walked to the bank of Baihe River in his hometown and saw many poor people suffering from hunger and cold, and their ears were rotten by the frost. He felt very sad and determined to save them. When Zhang Zhongjing returned home, there were so many people seeking medical treatment that he was very busy, but he always kept in mind the poor people whose ears were rotten by the cold. He imitated the method in Changsha and asked his disciples to set up a medical shed and a large pot on an open space in Dongguan, Nanyang. They opened it on the winter solstice and gave medicine to the poor to treat their injuries. Zhang Zhongjing's medicine is called "Quhan Jiao Er Soup". The method is to boil mutton, pepper and some cold medicine in a pot. After cooking, take these things out and chop them up, and wrap them in dough to look like ears. The "Jiao Er" was cooked in a pot and distributed to patients begging for medicine. Each person has two charming ears and a bowl of soup. After people take the Quhan Decoction, their whole body becomes hot, their blood becomes smooth, and their ears become warm. After taking it for a period of time, the patient's rotten ears will be cured. Zhang Zhongjing continued to give up medicine until New Year's Eve. On the first day of the Lunar New Year, people celebrate the New Year and the recovery of rotten ears. They make New Year's food like Jiao Er and eat it on the morning of the first day of the Lunar New Year. People call this kind of food "dumpling ears", "dumplings" or partial eclipse, and eat it on the winter solstice and the first day of the new year to commemorate the day when Zhang Zhongjing opened shed medicine and cured patients. Zhang Zhongjing was born nearly 1,800 years ago, but the story of his recipe of "Quhan Jiao Er Soup" has been widely circulated among the people. Every winter solstice and New Year's Day, people eat dumplings and still remember Zhang Zhongjing's kindness in their hearts. Today, we no longer need to use Jiao'er to treat frozen rotten ears, but dumplings have become people's most common and favorite food.
