Actually, I also often exercise in the evenings too, so on some days I'll have two workouts -maybe a bike in the morning and swim in the evening, for example.

其实，我在晚上也常常锻炼，所以在一些日子里我将会锻炼两次——比如可能是早上骑车、晚上游泳。

And Hangzhou is often foggy in the morning before sunrise, emissions, and exhaust gas collected under the tree, so if you do exercise there, you are breathing those polluted air.

而且杭州雾天比较多，没出太阳前，废气、尾气都被压在树下面，这时去树下锻炼吸的都是废气。
