Dumplings are a favorite traditional food of our people. It is made of flour to make a thin and soft dumpling skin, and then chopped fresh meat, cabbage, etc., mixed with condiments for the filling, wrapped into a pot and boiled until the dumplings float to the surface of the water can be. The dumplings are characterized by their thin skin, tender filling, delicious flavor, and unique shape. Dumplings were originally called "Jiao Er" and were first invented by Zhang Zhongjing, the sage of medicine in China. At the end of the Eastern Han Dynasty, there were serious disasters all over the country, and many people suffered from diseases. In Nanyang, there was a famous doctor named Zhang Ji, the word Zhongjing, since childhood, study hard medical books, learn from all the strengths, become the founder of Chinese medicine. Zhang Zhongjing was not only a skillful healer who could cure all kinds of difficult diseases, but also had high medical ethics. He treated both the poor and the rich seriously, and saved countless lives. When Zhang Zhongjing was an official in Changsha, he often treated the people. One year, when the local plague was prevalent, he set up a cauldron at the entrance of the government office and saved people's lives by giving medicine, which was y loved by the people of Changsha. After Zhang Zhongjing returned home from Changsha, 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 frozen. He was so upset that he was 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 remembered those poor people with frozen ears in his heart. He modeled his medicine after what he did in Changsha, and asked his disciples to set up a medical hut and a cauldron in a vacant lot in Dongguan, Nanyang, and opened the hut on the winter solstice to give medicine to the poor people to cure their injuries. Zhang Zhongjing's medicine called "dispel cold Jiao ear soup", the practice is to use mutton, chili and some dispel cold herbs boiled in the pot, boiled and then fish out these things chopped up, wrapped in dough into an ear-shaped "Jiao ear", boiled in the pot and distributed to patients begging for medicine. Each person has two ears and a bowl of soup. People ate the soup to get rid of cold body heat, blood flow, two ears warm. After eating it for some time, the patients' rotten ears were cured. Zhang Zhongjing She Medicine lasted until the 30th day of the New Year. On the first day of the Lunar New Year, people celebrated the New Year and the recovery of the rotten ears, so they made New Year's food in the form of "Jiao Er" and ate it on the morning of the first day of the Lunar New Year. People called this food "dumpling ear", "dumplings" or partial food, eaten on the winter solstice and the first day of the year to commemorate the days when Zhang Zhongjing opened the shed for medicines and cured the patients. It has been nearly 1,800 years since Zhang Zhongjing's death, but the story of how he made "Jiao Er Tang" to get rid of the cold has been widely spread among the people. Every winter solstice and the first day of the Lunar New Year, people eat dumplings and still remember Zhang Zhongjing's kindness in their hearts. Today, we do not need to use the delicate ear to cure frozen ears, but dumplings have become the most common and favorite food.
