A special bus line themed waste sorting was put into operation in Hangzhou's West Lake Scenic Area on April 18.

The waste sorting cartoon is painted on the bus. The promotional slogans are posted and knowledge of waste sorting is broadcast inside the bus.

The bus includes popular tourist bus lines, such as West Lake Inner Ring Line, Outer Ring Line, and Bus 7.

When taking a bus, citizens and tourists can learn about waste sorting, which helps to promote waste sorting in a bid to make Hangzhou more livable and beautiful.
