Why should firecrackers be set off during the Spring Festival?

1, setting off firecrackers in the Spring Festival makes the atmosphere lively and adds a stronger flavor of the year; Setting off firecrackers also symbolizes the farewell of the old and the welcome of the new, expressing people's yearning and wishes for a better future.

According to legend, there was a fierce monster called Nian in ancient times, which was in the deep sea all the year round, but at the turn of the old and the new, it came out to trample on crops and hurt people and animals, and the people complained bitterly. Once it went to the village to do evil again and was scared away by the red clothes hanging at the door. When I arrived at another place, I was scared by the lights and ran around.

3. So people have mastered the weakness of Nian's fear of sound, red and fire. At the end of each year, people put up red couplets at home, set off firecrackers and hang red lights, burn firewood in the yard, and chop vegetables and meat with kitchen knives, making a noise. So everyone should set off firecrackers during the Spring Festival.
