Jiaozi is used to eating in the evening of off-year in the north, which means sending away the kitchen god and "sending away the windward side of jiaozi". When offering wine, jiaozi should be placed on the platform. In addition, there is a folk saying "delicious but not as good as jiaozi". During the Spring Festival, jiaozi has become a timely and indispensable food.

Many northern provinces and cities have been gradually led by Jiaozi, but there is one exception, that is, Henan. In Henan, every household has to cook and eat by themselves, and burning a fire is almost equal to having a folk song "Twenty-three, Sticking Cakes and Sticks" in Luxi, Shandong Province in the next year. On the 23rd day of the twelfth lunar month, every family steamed and ate sticky cakes, which means to stick the mouth of the kitchen god and let him speak good things in the sky instead of bad things in the world. The sticky cake is made of yellow rice and red dates. It is sweet and strong, and the entrance is soft, which means "high every year". There is a saying in the northwest of Shanxi that "you can't chew your fingers if you eat sesame candy on the 23rd". It is said that off-year is the day when the Kitchen God goes to heaven. He will report to the Heaven Emperor about the world's food and clothing consumption in the past year and other things that the Heaven Emperor wants to know. That is, the kitchen god's debriefing day. Eating sesame candy is to make the kitchen god's mouth stick with sugar. He can't report the delicious and luxurious scenes of the world to the sky, so as not to punish people who love to eat and drink, bring famine to the new year, and look forward to a safe and prosperous year. In the southeast of Shanxi, the custom of eating fried corn is popular. A folk proverb says, "Twenty-three, if you don't eat fried corn, it's on New Year's Eve-a pot is poured." People like to stick fried corn and maltose together, and then freeze them into pieces, which are crisp and sweet to eat.
