A monk returns home by taking the train from Lhasa, capital of Southwest China's Tibet autonomous region, to Xining, capital of Northwest China's Qinghai province, on the Qinghai-Tibet railway on May 27, 2016. Since the opening of the railway a decade ago, the number of passengers paying pilgrimage to Lhasa has been on the rise. From early December to the end of January the next year, more than 60 per cent of passengers on the train K9801, heading from Xining to Lhasa, were pilgrims. [Photo/Xinhua]
