Fireworks, also known as sparklers, fireworks and sparklers, were invented by the working people of the Han nationality. They are mainly used for military, grand ceremonies or performances, and the only event in modern China and the world where fireworks can be set off on the same day is the New Years Eve (New Years Eve) event. In order to protect the environment, many fireworks recipes do not use substances containing heavy metals and sulfur elements, reducing the production of sulfur dioxide and other sulfides. By changing the amount of oxidant and combustibles to control the combustion reaction, the oxygen balance and combustion temperature of the system can also be changed. The Chinese New Year is coming soon, and children can watch beautiful fireworks again.
