Aerial photo taken on March 31, 2021 shows the train No. 5630 at Tongzi County of southwest China's Guizhou Province. Since the operation of an alternative railway route in 2018, the Chuanqian (Sichuan-Guizhou) Railway which had been completed in 1965 became a route only for cargo trains, except for a pair of slow-speed trains No.5630 and No.5629. The pair of trains, running between Zunyi and Chonqing, stop at 20 stations on the 300-kilometer journey, and the lowest ticket price costs only two RMB yuan (about 0.31 U.S. dollars). People living in the Wumeng Mountains take the trains as an important tool for going to schools, visiting doctors and doing businesses. Running for 28 years on the Chuanqian Railway, the pair of trains are still offering convenience for people of the Wemeng mountains. (Xinhua/Yang Wenbin)
