Zhang Zhongjing, a famous doctor in the Eastern Han Dynasty, developed a therapeutic prescription to keep out the cold. On the solstice of winter, he set up a shed, put the medicine, boiled mutton and cold-dispelling medicine together, wrapped the dough bag into the shape of an ear, and then cooked it in the previously cooked soup, named "cold-dispelling Joule soup". After drinking it, the people felt hot all over, their ears were burning and their ears were getting rotten. Zhang Zhongjing's Joule gradually evolved into the present jiaozi. This is the origin of eating jiaozi on the solstice in winter.

Every winter solstice, people imitate Joule and make "Joule" or "flat food" with flour, which is now jiaozi. Later, there was a saying that eating jiaozi on the winter solstice would not freeze your ears. So every winter solstice, people eat jiaozi anyway.

Ping 'an Fruit can be called Apple, because "Apple" is also a homophonic word for Ping 'an Fruit, so send an apple. There is no unified statement about legends. Sending apples is also a homonym from China.

Christmas Eve is Christmas Eve, Christmas Day is 65438+February 25th, and Christmas Eve is the night of 65438+February 24th. Apple's "Ping" and its homonym are the auspicious meaning of Apple's "Ping" in China. So there is a custom of sending apples on Christmas Eve. Those who send apples on behalf of others wish those who receive the fruits of peace a safe and secure New Year.
