1, firecrackers with the old and welcome the new, meaning the new year's good intentions. Legend has it that in ancient times, there is a fierce beast called "year", all year round in the deep sea, but at the turn of the new and old years, will come out to trample the crops, harming people and animals, the people complained of endless suffering. Once it came to the village to do harm, but was scared away by the big red clothes hanging in front of a house. When it came to another place, it was scared by the light and ran away. So people have learned that the "year" is afraid of sound, red color and firelight. At the end of each year, people will be in front of their homes, red couplets, firecrackers, hanging red lanterns, burning firewood in the yard, close the fire, chopping vegetables and meat with kitchen knives, making noise. So everyone has to set off firecrackers on New Year's Day.

2, to the period of the North and South Dynasties, people burning firecrackers on New Year's Eve has formed a custom. "Jing Chu chronicle" recorded this custom: "the first day of the first month, is the day of the three yuan. Called the end of the month, the rooster rises, first in front of the court firecrackers, burning grass, in order to avoid the mandrill evil spirits." This is also the origin of firecrackers later in the Spring Festival. It can be seen that the word "firecracker" is the original meaning of the word is to burn bamboo and burst. After the invention of gunpowder, people no longer burn bamboo, but will be saltpeter, sulfur, charcoal, etc. filled in the bamboo tube burning, resulting in "firecrackers". However, at this time, people have been using "firecrackers" called, until today.
