Yang Chenxue (R) and her colleague help an elder passenger who is traveling alone board the train in advance at Lanzhou Railway Station in Lanzhou, capital city of northwest China's Gansu Province, Jan. 5, 2020. Yang Chenxue is a train attendant from China Railway Lanzhou Group Co.,Ltd. She used to broadcast railway information with a loudspeaker. As time passed by, the loudspeaker was updated with a new microphone. As the Spring Festival travel rush is approaching, attendants like Yang Chenxue are getting busier. Their duties include checking passengers in, inspecting the waiting room and helping passengers in need. Small yet helpful, attendants' work makes passengers' travel more convenient and smoother.
