How to treat firecrackers as single-layer or double-layer?

The difference between single-layer and double-layer firecrackers lies in the different sound levels of explosion. The two floors burn louder together, and firecrackers are almost set off in modern traditional festivals, weddings, celebrations, temple fairs and other occasions, especially during the Spring Festival, the use of firecrackers exceeds half of the annual consumption.

The origin of firecrackers has a history of more than 2000 years. In ancient China, when there was no gunpowder and paper, people burned bamboo to make it burst and make a sound, so as to drive away the plague. Because of the crackling sound when bamboo burns, it is called firecrackers. Setting off fireworks on festivals or festive days reflects the good wishes of the ancient working people in China for Antai.
