The Nian is a mythical beast in Chinese folklore that is said to appear on the eve of the Lunar New Year, often attacking villages and causing destruction.
It is believed that the Nian is afraid of the color red, loud noises, and fire, which is why people traditionally set off fireworks and hang red decorations during the New Year celebrations to ward it off.
The Nian is also associated with the zodiac animal of the year, with each year being represented by a different animal in the Chinese zodiac cycle.
