早冬的天黑天，踏着枯叶，呲嗒呲嗒地漫步，无思无想。
路上行人来来往往，街道两旁的商店动火明亮，车辆川流不息。然而，糟糕的是，空气污染严重。
On a dark day in the early winter, walking on the dead leaves and staggering, I have no thoughts.
The pedestrians come and go, the shops on both sides of the street are bright and the cars is constantly flowing. However, what is bad is that air pollution is serious.
