Four trains put doctors on track to open eyes in remote regions

This is the 13th year Dong Shuzhen has left Beijing on an eight-month trip to help blind people in remote areas see again.

Dong is in charge of a set of four four-carriage eye hospital trains, supported by an NGO called Chinese Foundation for Lifeline Express, which was founded in 1997 in Hong Kong. At the time, it received enough funding from citizens and local government to buy a single train.

Shortly after it was set up, the NGO was passed to the mainland as a present to mark the return of Hong Kong. A local branch was later established in 2002, called the Beijing Foundation for Lifeline Express.
