Workers sort out parcels beside a conveyor belt in a transfer center of YTO Express in Shanghai, east China, Nov. 11, 2014. Courier service companies saddled up to take on delivery tasks as e-commerce giants vied with rivals to snare online shoppers during the week-long shopping bonanza around Nov. 11, nicknamed as "Singles' Day." According to latest figures published by the State Post Bureau (SPB), a total of 500 million parcels are expected to be delivered during the week-long shopping spree, almost doubling the figure of the same period of last year.
