City clears the way for a green future

Chongqing was known as "fog city" in the 1980s and '90s when it suffered through more than 100 days of heavy air pollution every year.

But the municipality's 30 million residents are now enjoying a greater number of clear days due to government efforts in recent years to improve environmental protection. Last year, the air quality index showed 316 days of the year were either "good" or "moderate".

During his inspection tour of Chongqing in 2016, President Xi Jinping urged the municipality to become a pleasant place with clear water and green mountains.
