1, the origin of eating jiaozi on the winter solstice:
It is said that Zhang Zhongjing was an official in Changsha, and when he retired from his old age, he was just catching up with the winter 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.
Zhang Zhongjing is very concerned about those people whose ears are frozen and rotten. He has developed a therapeutic prescription that can keep out the cold. 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".
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.
2, eat noodles on the summer solstice:
Eating noodles on the summer solstice in the south of the Yangtze River is an important custom in many areas. There is a saying among the people that "eating noodles on the summer solstice makes a day shorter". There are many kinds of noodles in the south, such as Yangchun noodles, dry soup noodles, shredded pork noodles, three fresh noodles, noodles with sesame oil and cold noodles, while noodles with gravy and Zhajiang Noodles are in the north. "Because the new wheat on the summer solstice has appeared, eating noodles on the summer solstice also means tasting new things."
