Fireworks has been banned for Chinese New Year.
In China’s capital city, Beijing, along with more than 400 other towns and cities, people be celebrating it more quietly than normal.
The ban on fireworks is because of worries about high levels of pollution in the country and fears that the chemicals used in fireworks are part of the problem.
This rule is surprising as fireworks are usually a traditional part of Chinese New Year.
How bad is pollution in China?
Children who go to school in China sometimes have to where masks to help them filter the air they breathe
Pollution can be measured in different ways, but the World Health Organisation (WHO) use a scientific calculation that measures the number of small particles in the air which can be breathed in.
They recommend that an average reading of 10 micrograms per cubic metre is a safe amount over a year, but shouldn’t go over 25 micrograms per cubic metre in one day.
Levels in China’s capital city Beijing in recent years have regularly been higher than 400 micrograms, and around 600 in the city of Shijiazhuang.
In 2014 China’s government said that they were going to start working to reduce the amount of pollution in the air.
