Disabled couple builds mountain roads in southwest China

In 2012, Zhang Jiwen and his wife began to build roads at their own expense in the deep forests of Fuling County, Chongqing Municipality. Though Zhang has a hearing disability and his wife has an eye condition, they managed to finish the construction of a major mountain road that makes life easier for surrounding residents. The couple is now working on a second mountain road, which is an even tougher task than the first.
