Winter solstice is an important solar term among the 24 solar terms. In ancient times, there was a saying that the winter solstice was as big as a year. Radish has the name of ginseng, and jiaozi eats it on the solstice in winter. It is suggested to use radish as stuffing, which is healthy and delicious.

Jiaozi needs 1 radish, 500g pork, 1 tbsp thirteen spices, 10g salt, a little onion, 1 tbsp cooking wine, 1 tbsp soy sauce, 2 tbsps soy sauce, a little chicken essence, 1 tbsp oyster sauce. Note that the radish should be shredded and blanched before cutting, so that the taste will be better.

When cutting the stuffing, you should use force to make the stuffing more tough. The steps of cutting stuffing should be gradual, the time of cutting thin should be reduced, and the time of cutting large pieces should be increased, so that the taste of stuffing will be better.

The origin of eating jiaozi from winter solstice.

According to legend, Zhang Zhongjing, a doctor from Nanyang, was an official in Changsha. When he retired in his later years, it was a snowy winter and the wind was biting. He saw that the villagers on both sides of the Baihe River in Nanyang were very sad, and many people's ears were frozen. He asked his disciples to set up a medicine shed in Guandong, Nanyang, put mutton and some herbs for dispelling cold in a pot, took them out and chopped them up, imaged their ears with leather bags, and then put them down and cooked them in a pot to make a medicine called "soup for dispelling cold and correcting ears" for the people to eat.

After eating it, the villagers' ears will be fine. Later, on the solstice of winter, people imitated and cooked, thus forming the custom of "pinching ears". Later, people called it jiaozi, while others called it "flat food" and "instant noodle jiaozi". It is also said that people will not be frozen in jiaozi after eating the winter solstice.
