      Workers reinforce tracks near the Tanggula Station of the Qinghai-Tibet railway, northwest China's Qinghai Province, June 30, 2018. Maintenance workers stick to their posts everyday to guarantee the operation of the Qinghai-Tibet railway at the Tanggula Station with an altitude of 5,072 meters above sea level.
