Related history:
Zhang Zhongjing was an official in Changsha. When he retired from his old age, it was just the winter of that year. The wind was biting and the snow was falling. On the edge of the Baihe River, Zhang Zhongjing saw many homeless people with sallow complexion and thin clothes. Because of the cold, their ears were frozen and rotten, and their hearts were very uncomfortable.
After returning home, because Zhang Zhongjing's reputation has long been famous all over the world, many people came to see a doctor. Zhang Zhongjing is responsive and busy all day, but although many people come to see a doctor, Zhang Zhongjing still misses those who have frozen rotten ears.
After research, he developed a therapeutic prescription that can keep out the cold, called "Quhan Jiaoer Decoction".
He told his disciples to build a shed in an open space in Dongguan, Nanyang, and put it on a big pot to give medicine to the poor. The opening day was the winter solstice, and the medicine given was "Quhan Jiaoer Decoction".
At the beginning, the soup for dispelling cold and jiao 'er was actually to boil mutton and some medicines for dispelling cold in a pot, take it out and chop it up after it is cooked, wrap it in a flour bag to look like an ear, then put it in a pot, and cook the stuffing-wrapped dough with the original soup.
After the dough bag is finished, it looks like an ear, and because its function is to prevent the ear from freezing, Zhang Zhongjing named it "Jiao Er".
Zhang Zhongjing asked his apprentice to give each poor person a bowl of soup and two "jiao 'er". People ate the "jiao 'er" and drank the soup, and they were warm all over and their ears were hot. No one ever frostbitten their ears again.
When Zhang Zhongjing was working in Changsha, he often treated the people in peacetime and was very loved by the masses. After retirement, the people of Changsha send representatives to visit their hometown every year.
As the saying goes, doctors can't cure their own diseases. Zhang Zhongjing is also a human being, not a god.
One year, Zhang Zhongjing was ill, and he knew that the lamp oil of life was about to burn dry.
People who came to visit him in Changsha said that there was a place with good geomantic omen in Changsha, and they wanted Zhang Zhongjing to live there after a hundred years, but people in Nanyang quit, and the two sides quarreled.
Zhang Zhongjing said: "After eating Changsha water, I don't forget the feelings of my parents in Changsha;" Born in Nanyang, I don't forget my hometown. After I die, you will carry my coffin from Nanyang to Changsha, and bury me where the spiritual rope breaks. "
In the winter of that year, Zhang Zhongjing drove the crane to the west. The day of death happens to be the winter solstice.
When the funeral procession went to the place where Zhang Zhongjing gave everyone "Quhan Jiaoer Soup", the coffin rope suddenly broke.
According to Zhang Zhongjing's instructions, we hit the tomb, disembark the coffin and fill the grave on the spot. The people of the two places, one for you and one for me, kept flowing, built Zhang Zhongjing's grave greatly, and built a temple for him in front of it. This is now the medical shrine.
Zhang Zhongjing died on the winter solstice, and made a soup for everyone to get rid of cold and charming ears on the winter solstice. In order to commemorate him, everyone has to eat jiaozi on the winter solstice, and they all say that when they eat jiaozi on the winter solstice, their ears will not freeze in winter.
Few people eat "Quhan Jiaoer Decoction", but after years of erosion, the custom of eating jiaozi on the winter solstice has been passed down. And the types and shapes of jiaozi have been greatly improved. Where there are China people, there are jiaozi, and jiaozi has become the representative food for family reunion, but the name of Zhang Zhongjing is rarely mentioned.
