His job is not a waste

Zhao Wenguang sees his job as contributing to the Expo, Yu Ran reports.

For Zhao Wenguang, collecting recyclable waste around Shanghai every day is also a way to work towards the Expo theme of "Better City, Better Life".

"Riding around and collecting recyclable waste before and during the Expo for me is special as I know that I'm working not only for myself but also as a way to welcome tourists from all over the world with a cleaner environment," Zhao, 44, said proudly.
