Which air quality is better in Beijing and Chengdu?

Generally speaking, the air quality in Chengdu is generally poor, generally at moderate to severe pollution levels. Beijing's air quality has also had certain problems in the past, but since last year, the Beijing Municipal Government has taken a number of measures to strengthen air management, such as implementing "loose coal control" and "construction site dust control" as required. To reduce the emissions of harmful substances such as PM2.5, and at the same time strengthen the control of environmental pollution such as vehicles, factories, and construction construction, the air quality has performed relatively well in cities across the country.

Therefore, from an overall perspective, the air quality in Beijing is generally better than that in Chengdu. But the specific situation depends on the specific details, such as weather and local environment, which will affect air quality.
