The historical origin of firecrackers:

This custom has a history of more than 2500 years in China. The Story of Jingchu Times once recorded that on the first day of the first month, when the rooster crowed for the first time, everyone got up and set off firecrackers in their own yard to drive away the evil spirits of plague.

At that time, there was no gunpowder and paper. People burned bamboo to make it burst and make a sound, so as to drive away the plague. This is superstition, of course, but it reflects the beautiful desire of the ancient working people in China for Aetna.

Firecrackers in the Tang Dynasty, also known as "blasting poles", probably burned a long bamboo pole piece by piece and made a continuous popping sound. Nanchang poet Lai Hu's poem "Early Spring": "The new calendar is only half open, and the pavilion is still bursting." This is the scene of burning bamboo poles during the Spring Festival.

Later, after constant chemical experiments, alchemists found that saltpeter, sulfur and charcoal together could cause combustion and explosion, so they invented gunpowder. Some people put gunpowder in bamboo tubes and detonate it loudly, thus replacing the ancient custom of burning bamboo. In the Northern Song Dynasty, there were fireworks wrapped in paper powder in our country, which were divided into single ring and double ring. They were renamed as "firecrackers" and later changed to "firecrackers".
