Zhoushan in East China's Zhejiang province ranked third among 168 major Chinese cities in terms of air quality, the Ministry of Ecology and Environment recently announced.

Zhoushan is known for its blue skies, and the city has been listed among the top 100 cities with the best air quality by Philippines-based Clean Air Asia for many years, with its overall score sitting around 98 points.

According to the Zhoushan Weather and Climate Bulletin in 2022, the number of cloudy days in Zhoushan was 42, nine days fewer than the year before, while the number of smoggy days was four, eight days fewer than in 2021.

In 2008, the Zhoushan meteorological department launched the blue-sky index, which categorizes blue skies into five classes based on air quality, with the first class being the best.

Zhoushan has also taken measures to reduce air pollution in recent years. Statistics show that in 2022, the concentration of PM 2.5 in the city was 15 micrograms per cubic meter, down 11.8 percent year-on-year, and its good air quality rate was 98.1 percent, ranking first in Zhejiang province.
