A large part of China experienced larger amounts of smog ( 雾霾 ) than usual this January and the air was badly polluted. The distance ( 距离 ) one could see was shorter than 1,000 meters in Beijing, Tianjin, and the provinces of Hebei, Henan, Shandong and Anhui. In some areas, it was down to 200 meters.

People usually set off firecrackers ( 爆竹 ) to celebrate Spring Festival. But because of the smog, this year seemed very quiet. It was really different. A man called Zhang Wei said that his friends and he hadn’t set off a single firecracker.

“ We all suffered ( 遭受 ) from last month’s smog. If we don’t call an end to the firecrackers, the environment will get worse and worse during the holiday. ” said Zhang Wei. He called on more people to set off fewer firecrackers during this year’s Spring Festival by putting up a notice in his neighborhood.

More Chinese looked forward to celebrating ( 庆祝 ) the holiday in a greener way . They decided not to set off firecrackers. They also decided not to waste food . They said the new celebrations sounded fashionable.

To clean the sky ,more than ten provinces including Guangdong, Zhejiang  and Jiangsu have started to use national 4 standard ( 标准 ), which is expected to reduce ( 减少 ) vehicle emission ( 车辆排放 ) by 30% to 50%. Beijing even has started to use the stricter national standard.

We still have a lot to do to improve the air quality. For example, using public transportation as much as possible is not a hard thing for us to do, but it matters a lot .
