Shot in the city of Shanghai, China.
When I walked, I came to a small tunnel. And there was a traffic light at the tunnel exit. I saw many bicycles and tricycles stopping. They started to run when the traffic light turned green.
Shanghai was emerging. Many cars were running in Shanghai though, many bicycles were still running along the automobiles. Automobiles seemed to be still expensive for the average persons. However, if all dwellers used an automobile, the air pollution could become worse.
