Customs and habits of New Year's Day:

When China just started to celebrate New Year's Day, the customs and habits it celebrated were of course mostly similar to the Spring Festival, or a scaled-down version of the Spring Festival. Although some traditional ways of celebration are followed, such as setting off firecrackers, killing Sansheng, worshipping ghosts and gods, and worshipping ancestors, they do not occupy much important position in people's minds.

In modern times, the custom of celebrating New Year's Day is simpler. Now it is more common to organize activities by groups, such as New Year's Day parties, hanging slogans to celebrate New Year's Day, or holding collective activities.

The traditional way of celebrating in China lies in the people, especially in the countryside. Every new year's day, every household will set off firecrackers, kill chickens and geese, and after worshipping the gods of all parties, it is a family reunion and a meal.
