The origin of firecrackers can be traced back to the Han Dynasty in my country, and they developed most vigorously during the Tang and Song dynasties. In summary, firecrackers can be divided into three categories: those for listening to the sound, those for viewing flowers, and those for listening and viewing. The origin of firecrackers was to listen to the sound, and the development of firecrackers had "Ma Lei Zi", which had a single sound. Then there was a double-sound firecracker called "two kicks". Then all kinds of fireworks were developed from two kicks, which shows that two kicks are an important stage in the history of the development of fireworks.
