China calendar is based on the combination of the movements of the moon and the sun. The lunar cycle is about 29.5 days. In order to "catch up" with the Gregorian calendar, China people add an extra month every few years (/kloc-7 years in the 9-year cycle), which is the same as adding an extra day in a leap year. This is why, according to the solar calendar, China New Year comes on a different date every year.
New Year's Eve and New Year's Day are a family gathering, a time of reunion and gratitude. Traditionally, celebrations are highlighted by a religion that pays tribute to heaven and earth, the god of the family and the ancestors of the family.
The ceremony is the most important of all ceremonies, which connects the living members with the dead members. People cherish great respect for their dead relatives, because they laid the foundation for the wealth and glory of the family.
The existence of ancestors was recognized on New Year's Eve, and a dinner was arranged for them at the family banquet table. The souls of ancestors and the living people celebrate the beginning of the new year as a big group. Known as the "fireplace" or Lu Wei's public banquet. It symbolizes family unity and respect for past and present generations.
