The custom of celebrating the New Year from 30 to 15.

The main activity of observing the Year is to protect Jiaozi. On the first day of the first lunar month (0 1 February), in the traditional custom, people who pay New Year greetings on the first day of the first lunar month must be elders or neighbors, and generally do not go far away to pay New Year greetings. After New Year's Eve, people open doors on the first morning to congratulate each other.

The 30th of the twelfth lunar month, also called New Year's Eve, refers to the last day of the twelfth lunar month, which is connected with the Spring Festival (the first day of the first month). On New Year's Eve, people will bid farewell to the old and welcome the new, which means that the old year will be removed here and the new year will be replaced next year. Northerners are used to eating jiaozi in the New Year, while the South has the custom of eating wonton in the New Year. Eating noodles in the new year is to hope to live longer. Keeping old age on New Year's Eve is the most important custom, which was recorded in Wei and Jin Dynasties.

Eating Yuanxiao as a food on the 15th day of the first month has a long history in China. Yuanxiao is "rolled" in the north, and Tangyuan is "wrapped" in the south. These are two foods with different practices and tastes, but both symbolize round and colorful lanterns. Lantern Festival is also called Lantern Festival. Lantern Festival is a traditional custom of Lantern Festival, which began in the Western Han Dynasty and flourished in Sui and Tang Dynasties. After the Sui and Tang Dynasties, the lantern style prevailed throughout the ages and spread to future generations. Dragon dancing lanterns are also called dragon dancing or dragon dancing. Its origin can be traced back to ancient times.
