An officer of Qingshiya Railway Station makes a phone call by the cliff side with weak phone signal in Baoji City, northwest China's Shaanxi Province, Jan. 7, 2020. Qingshiya Railway Station is at the peak of Qinling Mountains on China's first electrified railway, Baoji - Chengdu railway. Surrounded by sheer cliffs, the "cloud station" consists of only two tracks and serves as a short stop for passing trains on the railway. Small as it is, the station has all the vital organs. To guarantee the operation of the railway station, station staff members are working on 24/7 coverage. Staff on duty have to stay at the station for the whole five days and six nights. Even the commuting itself is not easy. Facing the arduous terrain, they have to walk for almost an hour passing through rugged mountains to take the bus home. Although the condition is challenging, the young staff team makes excellent work performance and lives a colorful life at the top of Qinling Mountains. Currently, the 10-person team consists of nine post-90s officers with the manager born after 1985. Together with their colleges who used to work here, they constructed small gardens, flattened basketball courts, installed fitness equipments, and even built the memorial hall recording the history and spirit of the Qingshiya Station over decades. Since the official opening of Baoji - Chengdu Railway in July 1956, generations of Qingshiya people have guarded the station for over 60 years. These people's strong work ethic guarantees the safe operation of trains. (Xinhua/Tao Ming)
