The Spring Festival falls on the first day of the first Chinese lunar month and celebrations last from the 23rd day of the 12th lunar month to the 15th day of the first lunar month the following year. It is based on an ancient legend where a monster named Nian was scared away by loud noises and the color red, leading villagers to light firecrackers and decorate with red to celebrate being safe from the monster each year. Today, Spring Festival customs include sweeping away dust, pasting couplets, setting off fireworks, giving money in red envelopes, eating dumplings and fish, temple fairs, and welcoming in the new year.
