A crowded carriage of a train on the No. 11 Subway Line in Shenzhen City, South China’s Guangdong Province, July 21, 2016. The train has two kinds of carriages, with the cost of a ticket in the business class one three times more than a standard fare. As a result, the better-equipped business carriage is almost empty and the ordinary often crowded after it started running less than a month ago. Some residents have complained the separation is unnecessary. (Photo/IC) DDDDFFF
