China people have been eating jiaozi for over 1800 years. Before jiaozi appeared, similar food was called wonton, and the history of wonton can be traced back to the Han Dynasty 2000 years ago. In addition to the literature, we can also see the complete jiaozi and wonton in Tang Dynasty more than 300 years ago. They were unearthed from Xinjiang. A jiaozi and four wonton are put together in a wooden bowl, the shape of which is the same as that of jiaozi and wonton now. According to research, today's jiaozi is the ancient wonton. Wonton is a traditional food in China, which originated in northern China. In Dialect written by Yang Xiong in the Western Han Dynasty, it is mentioned that "the name of the cake is wonton". Wonton is a kind of cake. The difference is that it is filled with stuffing and eaten after being cooked. If cooked in soup, it is called "soup cake". Wonton, shaped like a crescent moon, was also used for sacrifice at first. Until the Song Dynasty, every winter solstice, all the shops in the town were closed, and each family made wonton to worship their ancestors. After the sacrifice, the whole family shared wonton. There are more than ten kinds of fillings in a plate of rich people's sacrificial wonton, which is called "Baiwei wonton". After the Southern Song Dynasty, wonton was sold as a snack in restaurants.

China ancient people thought it was a sealed steamed stuffed bun, which had no seven tricks, so it was called "chaos". According to China's word formation rules, it was later called "Wonton". Wonton is no different from jiaozi at this time. Jiaozi has not changed obviously for thousands of years, but wonton has developed in the south and has an independent style. Since the Tang Dynasty, there has been a formal distinction between wonton and jiaozi. There used to be a saying in old Beijing that "winter solstice wonton, summer solstice noodles". According to legend, during the Han Dynasty, the Xiongnu in the north often harassed the frontier, and the people were restless. At that time, there were two leaders, Xiongnu tribe and Tun tribe, which were very cruel. The people hated it, so they wrapped it into a corner with meat stuffing and called it "wonton" with the sound of "muddy" and "swallowing". I hate eating, and I want to quell the war and live a peaceful life. Because wonton was originally made on the winter solstice, every family eats wonton on the winter solstice.

There is another saying: On the day of the winter solstice, there are grand ceremonies on all the streets of the capital. At the beginning of the Yuan Dynasty, the Taoist took a kiss and went to the table to celebrate the Buddha's birthday. According to Taoism, the Buddha in the early Yuan Dynasty symbolizes the first century when chaos and Taoism were not divided. Therefore, people have the custom of eating wonton. "Yanjing Years Old" says: "The shape of husband's wonton is like a chicken egg, which is quite similar to the chaos of heaven and earth, so it is eaten from winter to the sun." In fact, "wonton" and "chaos" are homophonic, so people extend eating wonton to break the chaos and create the world. Later generations no longer explain its original meaning, but spread the proverb "Wonton from winter to the sun, and from summer to the sun", treating it simply as a seasonal diet.
