Second, according to the explanation of folk customs:
1, "New Year's Eve" is the day when people and ghosts fight. Therefore, everyone must participate in order to achieve auspicious peace in the coming year.
2, the ghost is "evening", it is a spectre born because of the bad luck of the world in the past year. "Xi" will come out on December 30 of the lunar calendar, at the turn of the old and the new. It will be harmful to the world! At this point, it needs God Qi Li to get rid of it. On the 30th day of the twelfth lunar month every year, God sends Nian, the god of the family, to exorcise the demons and ghosts on the earth, but Nian's skill on New Year's Eve is only 90%, which proves that the ghost of Xi is very powerful, and someone must help him to get rid of Xi. Therefore, people should set off firecrackers at midnight on New Year's Eve to help Nian get rid of the ghost "Xi" that harms the world.
On New Year's Eve, when people eat jiaozi, they will feel full of energy. Then, men, women and children will set off firecrackers to help the gods drive away ghosts, and then piously post new portraits of the kitchen god, and provide jiaozi-based food in front of the portraits of the God of Wealth and the kitchen god to express the meaning of peace and good luck in the coming year. This is the origin of the custom of "firecrackers sound farewell to the old year".
Third, according to the literature:
The custom of eating jiaozi during the Spring Festival appeared in the Ming Dynasty at the latest. Then it is particularly noteworthy that by the Qing Dynasty, this custom became very common and had been fixed. This custom is related to the ancient timing method in China. In ancient China, the Twelve Earthly Branches were used to record the time of day. We divide every day into twelve time periods, so the beginning of every day is noon, which is equivalent to the time from 23: 00 to 1: 00 in the middle of the night. Then at the end of each year, at the age of 30, this is not only the replacement of the old and new days, but the replacement of the old and new years. People in China call it "jiaozi".
Fourth, the origin of jiaozi:
Jiaozi originated in the era of Zhang Zhongjing, and "jiaozi" is also called "jiaozi" or "Joule", which means the alternation of the old and the new, and it is also a feast that must be eaten according to God's will. Otherwise, God will delete your name from the world of Yin and Yang, and you will become an unrecorded ghost after death. Think about it, how much our ancestors paid attention to this! Anyway, in order to get rid of the bad luck for a year, you should eat "jiaozi" on New Year's Eve. People from afar will cross the mountains and rivers and return to their hometown to eat the winter festival in jiaozi with their families to show that they have a happy home.
