Why can't fireworks be set off during the Spring Festival?

1, fireworks will produce a lot of harmful gases such as sulfur dioxide, nitrogen dioxide, carbon dioxide, carbon monoxide and dust of various metal oxides. When it is discharged in large quantities, if it happens in windless or low-pressure weather, and harmful gases cannot be dispersed for a while, it will strongly stimulate people's respiratory tract, make people cough and cause respiratory diseases such as tracheitis.

2. The loud noise caused by setting off fireworks makes it difficult for the elderly to sleep, the patients are frightened and the students can't study and rest quietly. Many times, pedestrians will be frightened by the sudden loud noise during the discharge, which is likely to lead to very serious consequences for patients with heart disease.

3. Especially in urban areas, buildings are getting higher and higher, and the population is denser. The discharge of high-altitude fireworks can easily lead to fire, which directly endangers people's lives and property.
