Jiaozi is used to eating in northern off-year evenings, which means to see the Kitchen God off and to "see off the windward side of jiaozi". When offering, jiaozi should be put on the platform. In addition, there is a folk saying that "it's 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 gradually been led by jiaozi, but there is one exception, that is, Henan. In Henan, every family should cook their own fire to eat, and fire is almost equal to off-year There is a folk song "Twenty-three, Sticking Cake Sticking" in Luxi area of Shandong Province. Every year on the 23rd of the twelfth lunar month, it is the day when every family steamed sticky cakes and ate sticky cakes, which means to stick the mouth of the kitchen king and let him say good things in heaven instead of bad things in the world. Sticky cakes are made of yellow rice and red dates, which are sweet and strong, and the entrance is soft, taking the meaning of "high year after year". There is a saying in the northwest of Shanxi that "if you eat sesame candy for twenty-three, you can't eat sesame candy and chew your fingers". It is said that off-year is the day when the kitchen god goes to heaven, and he will report to the Heaven Emperor about the food and clothing consumption of the world in the past year and other things that the Heaven Emperor wants to know. That is, Kitchen God's debriefing day. Eating sesame candy is to make the kitchen god's mouth stuck with sugar, and 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, and the folk proverb says, "Twenty-three, don't eat fried, on the New Year's Eve-one pot pours." People like to bond fried corn with maltose and freeze it into chunks, which tastes crisp and sweet.
