Why should we keep the traditional customs of the Spring Festival?

First, many traditional customs can help people who have worked hard for a year to rest and entertain, including going home for the New Year and having New Year's Eve dinner. Second, express everyone's love for life and seek good luck, including posting Spring Festival couplets and setting off firecrackers. Thirdly, China people have the recognition of the traditional customs of the Spring Festival in their blood. This is my opinion.
