Among all means of transportation, high-speed railway is the most favored for the Chunyun travelers. China's high-speed railway network tops the world with an estimated length of 35,000 km by the end of 2019. Traveling by high-speed rail is not merely fast but also comfortable. Facilitated by new technologies, such as online booking and "face-scanning" check-in service, and advanced transport facilities, people have enjoyed shortened journey time as well as pleasant convenience. But to make all these happen, a large number of railway staff have to work with their utmost efforts during this busiest period of time for the whole year. Most of them are just ordinary workers unknown by the travelers they serve.
