Customs and legends of firecrackers:

Firecracker custom:

Every Spring Festival in China, lanterns are bright and gongs and drums are ringing. Firecrackers come and go, playing the Spring Festival song for the boiling earth. The sky is full of color and flowers are in full bloom, which has written a happy chapter for the festival.

He Xinchun, who set off firecrackers, has a history of more than 2,000 years in China. The earliest firecrackers refer to the explosion caused by burning bamboo, so they are called firecrackers. Speaking of the origin of firecrackers, there is an interesting legend.

The legend of firecrackers:

It is said that firecrackers originated from firecrackers. Since ancient times, there has been a saying that a long time ago, a beast named Nian appeared on the night of the Lunar New Year's Eve every year. In order to scare away this beast, people burn bamboo joints at home (or put red objects outside the house) because the air in the bamboo cavity expands when heated.

Make the bamboo cavity burst, thus making a loud noise, so as to drive away the Nian beast. With the invention of gunpowder, gunpowder firecrackers replaced the past bamboo firecrackers. According to legend, there was a monster named Nian in ancient China, with long tentacles and a ferocious face. Nian lived on the seabed for many years, and climbed ashore every New Year's Eve, eating livestock and hurting people's lives.
