Students read books borrowed from the mobile library at the student special carriages on train No. 6063 in China, May 27, 2018. The train No. 6063, which links 38 stations along the route from Baoji of Shaanxi Province and Guangyuan of Sichuan Province, serves thousands of students who live in mountainous areas and need to commute from schools to home every week. To improve services to the student passengers, student special carriages installed with bigger desks and a library were put into use at the end of 2017. With the approach of this year's International Children's Day, over 300 new books have been newly donated to the mobile library. (Xinhua/Li Yibo)
