Editor's note: New technology has been deployed at roads, train stations and airports to enhance travel efficiency and bring a convenient and comfortable experience to passengers during the 40-day Spring Festival travel rush, which began on Jan 26 and will last until Mar 5. Let's have a look!

1. Smart robots

Some stations along the Beijing-Zhangjiakou high-speed railway have introduced intelligent service robots, which have taken the job of guiding passengers, answering inquiries, and carrying heavy luggage.

The intelligent service robot has a closed storage box with a maximum carrying capacity of 100 kilograms. After placing bulky items in the storage box, passengers scan the code or undergo facial recognition to make the robot follow. In addition, the robot can also lead passengers to check-in points.
