[0002] Fireworks are also called "fireworks". my country is the hometown of fireworks. In the Sui and Tang dynasties when black powder was invented, some people put black powder into bamboo tubes and used fire wire to ignite them to make them explode. This was the early bamboo tube firecrackers. When people set off firecrackers, they often found that there was a phenomenon of fire spraying from the top of the firecrackers. Inspired by this, they created spray flowers, which were early fireworks. In the Song Dynasty, my country's fireworks products were of various varieties, and had different effects such as smoke, fire, light, and sound. In the Southern Song Dynasty, China began to hold a variety of large-scale fireworks parties, and many of the fireworks and firecracker production techniques at that time have been used to this day.
