Face recognition, smart robots and virtual reality are some of the new technologies that have been widely used for this year's travel rush during Spring Festival, or chunyun, between Jan 13 and Feb 21.
Face recognition machines have been added so passengers can quickly pass through railway stations in many cities, such as Beijing, Shanghai, Guangzhou, Zhengzhou, Taiyuan, Wuhan, Nanchang, Xi'an and Changsha.
These machines allow passengers to check their tickets by themselves while passing the safety-check gates, which takes each person only three to six seconds.
