Zhang Zhongjing is an official in Changsha. When he retired in his later years, it happened to be the winter of that year. The wind is biting and the snow is falling. On the edge of the Baihe River, Zhang Zhongjing saw many homeless people with sallow faces 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 here for medical treatment. Zhang Zhongjing is responsive and busy all day, but despite the large number of people who come to see a doctor, Zhang Zhongjing still misses those who have frozen ears.
After research, he developed a therapeutic prescription that can keep out the cold, which is called "Quhan Joule Decoction".
He told his disciples to build a shed in an open space in Dongguan, Nanyang, and put it on a cauldron to deliver medicine to the poor. The opening day was the winter solstice, and the medicine prescribed was "Quhan Joule Decoction".
At the beginning, the soup for removing cold was actually to boil mutton and some medicines for removing cold in a pot, take it out and chop it up after cooking, wrap it in a flour bag like an ear, then put it in a pot and cook the stuffed dough with the original soup.
After the bread is finished, it looks like an ear. Because its function is to prevent the ear from freezing, Zhang Zhongjing named it "Joule".
Zhang Zhongjing asked his apprentice to give each poor person a bowl of soup and two "corners". People eat "jiaozi" and drink soup, and their whole bodies are warm and their ears are hot. No one frostbites their ears anymore.
When Zhang Zhongjing worked in Changsha, he was always kind to the people and loved by the masses. After retirement, Changsha people 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 out.
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 in a hundred years, but the 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 never forget my hometown. After my death, you should transport my coffin from Nanyang to Changsha and bury me where the spiritual rope is broken. "
That winter, Zhang Zhongjing drove the white 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 a "cold-dispelling Joule soup", the coffin rope suddenly broke.
According to Zhang Zhongjing's instructions, we hit the tomb, disembark and fill the grave on the spot. The people of the two places came and went, and the stream continued, overhauling Zhang Zhongjing's grave and building a temple in front of it. This is now a medical shrine.
Zhang Zhongjing died on the solstice of winter, and made a charming ear soup for everyone on the solstice of winter. In memory of him, everyone eats jiaozi on the winter solstice. They all say that when they eat jiaozi on the winter solstice, their ears will not freeze in winter.
Few people eat "Quhan Joule Soup", but after years of erosion, the custom of eating jiaozi in winter solstice has been handed down. The types and shapes of jiaozi have also been greatly improved. Where there are China people, there are jiaozi, and jiaozi has become the representative food for family reunion, but Zhang Zhongjing's name is rarely mentioned.
