There are many theories about the origin of the Chinese New Year, the most popular of which is the legend of primitive beliefs and nature worship in early ancient times. At that time, people believed that "Nian" was a ferocious monster that would come out on the thirtieth day of the lunar month every year to harm people and animals, so people called the first day of the first lunar month "Nian". In order to resist the "New Year", people invented many methods, including setting off firecrackers, sticking Spring Festival couplets, eating Chinese New Year's Eve meals, etc., which gradually evolved into various Xi customs of the Spring Festival.
Another theory is that the Spring Festival originated from the first year of the year in ancient times, and has evolved into a folk festival that integrates removing the old and clothing the new, worshiping gods and ancestors, praying for blessings and warding off evil spirits, family and friend reunions, celebrations, entertainment and food. In ancient times, the Spring Festival was usually celebrated at the beginning of spring or the winter solstice, but after the Xinhai Revolution, China adopted the Gregorian calendar and officially designated the first day of the first lunar month as the Spring Festival.
Either way, the Spring Festival is one of the most important traditional festivals in China, with deep historical and cultural connotations. During the Spring Festival, various activities will be held across the country to celebrate the New Year, including New Year's greetings, Spring Festival couplets, reunion dinners, fireworks, worship gods and ancestors, etc., these activities have strong local characteristics and folk culture.
