   Engineers with China Railway Zhengzhou Group Co Ltd operate a robot to scan and check a bullet train in Zhengzhou, Central China's Henan province, on Feb 20, 2019. A growing number of robots are employed in China's railway system to improve efficiency and ensure safety, as railway trips are expected to hit 413 million in total during this year's Spring Festival travel rush, China's largest seasonal migration of people.
