Winter solstice jiaozi summer solstice noodles are the customs of two solar terms, saying that jiaozi should be eaten in the winter solstice and noodles should be eaten in the summer solstice. Summer solstice and winter solstice are not only two of the 24 solar terms, but also two of the traditional folk festivals. Every traditional festival in our country has its seasonal food.

The origin of jiaozi on the Winter Solstice is to commemorate Zhang Zhongjing, a "medical sage".

Eating noodles in the summer solstice is because it is just the harvest of wheat, and it is the most suitable to make noodles.

In the vast areas of China, the custom of "Winter Solstice jiaozi (wonton) Summer Solstice Noodles" has been passed down for thousands of years and has not changed. And whenever the younger generation and children in some families don't understand the meaning of eating jiaozi and wonton on the winter solstice and eating cold noodles and noodle soup on the summer solstice, their elders and adults will instill in them the folk custom of "noodles on the winter solstice in jiaozi".
