Setting off firecrackers and fireworks? It is a tradition that we have followed since ancient times, and it is also a traditional folk custom handed down by Chinese all over the world. Setting off firecrackers has long been an entertainment activity with national characteristics. Most festivals and entertainment activities in China are celebrated by setting off firecrackers and fireworks. These traditions are popular all over the country.

But nowadays, with the rapid growth of our population, the emission of automobile exhaust, if coupled with setting off firecrackers, will not only cause more serious air pollution, but also produce noise pollution. According to the data of the Public Security Administration of the Ministry of Public Security, there are currently 138 cities in China that prohibit the discharge of fireworks and firecrackers, including 5 provincial capitals, 30 prefecture-level cities and 103 county-level cities. Such as Beijing, Shanghai, Hangzhou, Chengdu, Harbin, Jinan and so on.

This not only means that people bid farewell to the old year and welcome the new year, but also set off firecrackers and fireworks to celebrate every major festival, such as marriage, building and opening. Setting off firecrackers can actually create a festive atmosphere, and it is also a symbolic entertainment of the festival, which can bring joy and good luck.

In our Han nationality, there is a saying called "open the door and set off firecrackers", which means that when the New Year comes, the first thing for every household to open the door is of course to set off firecrackers. Bang, bang, bang? Firecrackers bid farewell to the old and welcome the new, driving away wild animals and bad symbols. Firecrackers can be regarded as a specialty of China, and they can also be called "firecrackers", "firecrackers" and "firecrackers", with a history of more than 2,000 years.

But in fact, the noise of setting off firecrackers has a great influence on our physiology and psychology, which will not only damage our hearing, but also damage our cardiovascular system and our nervous system, which will make people feel impatient. In fact, it will also affect our sleep and cause fatigue.

In fact, fireworks and firecrackers are mostly made of chemicals. The discharged products will penetrate into the lithosphere, hydrosphere and atmosphere through various cycles in the biosphere, polluting water, soil and the air we breathe. Not only that, it will also cause haze weather. Infiltrated toxic substances can eventually enter the human body through the exploitation of the earth, endangering health, thus further worsening our living environment.
