年兽, or the "Nian Beast," is a mythical creature from Chinese folklore that is said to emerge at the beginning of the lunar new year. According to legend, it terrorizes villages, devouring livestock and even people. To protect themselves, villagers would use loud noises, bright lights, and the color red, which are believed to scare the beast away. The story of 年兽 is closely tied to the celebration of 春节 (Spring Festival), where traditions such as setting off firecrackers and decorating with red banners originated. These customs aim to ward off the Nian Beast and ensure a prosperous new year for families.
