A day in the life of a 'lap runner'

Huang Lijing, 33, is a conductor for high-speed bullet trains such as the C6035, a train in the Guiyang section of China Railway Chengdu Bureau Group Co Ltd. This year's Spring Festival rush marked the 15th year of her career as she continues to serve passengers with dedication and professionalism.

The C6035 runs in a circle on the Sichuan-Chongqing-Guizhou Ring Line and stretches over 1,300 kilometers, stopping at 16 stations along the way. Attendants on duty often describe their jobs as "running laps" with the train.
