Late at night, a group of pollution-absorbing workers in Guiyang North Railway Station wore straw sandals and walked along the slippery and even icy track to suck up the water for the high-speed railway trains from south to north. Since ordinary anti-skid shoes can no longer meet the anti-skid requirements, straw sandals have become the necessary equipment for the team members to work in winter, so they are also known as the "straw sandal team" guarding the high-speed railway. During the Spring Festival, the members of the "straw shoe team" worked for an average of 18 hours per shift to ensure the water demand of each high-speed train. (Xinhua News Agency)
