The origin of firecrackers has a history of more than 2000 years. In ancient China, when there was no gunpowder or paper, people used fire to burn bamboo to make it burst and make a sound, so as to drive out the God of pestilence. Because the burning bamboo made a "crackling" sound, it was called firecracker. This custom reflects the ancient Chinese working people's desire for peace and tranquility.
