Is Chongqing foggy or hazy?

There is smog in Chongqing, but fog is the most common in Chongqing.

The humidity in the fog is relatively high, and the water vapor in the air condenses into tiny water droplets suspended in the air. This phenomenon is fog, indicating that there is more dust in the air. Moreover, fog hinders traffic and does some harm to people's health. Fog is usually formed by air wetting.

The components of smog are complex, including mineral particles, sea salt, sulfate, nitrate and organic aerosol particles. Haze is more harmful than fog and poses a great threat to human body. The smog represents the extremely serious industrial pollution in this city.

Chongqing is actually a foggy city, not a foggy city. It's all Beijing now. . .

Isn't Chongqing a livable city?
