Despite the scorching heat wave, workers of rail grinding, a vital processing to the railway track, stick to their posts outdoors to ensure the progress of the Zhengzhou-Wanzhou railway construction. The Zhengzhou-Wanzhou railway links Zhengzhou in central China's Henan Province and Wanzhou in southwest China's Chongqing Municipality. The Henan section of the railway line is scheduled to be put into operation by the end of this year. (Xinhua/Li An)
