Where else would there be anything to see? There's haze at home, and there's haze there too ?

This hazy weather is different from that in China. The main source of pollution in China is chemical pollution, while the main source of pollution in this place is the burning of trees. Last August, I went on a tour of Banff with a group. It was held during the forest fire.
