Faces of Chongqing - Ran Guanghui, a 'Bangbang' Porter of the Mountain City

In 2010, a photograph of Ran Guanghui and his son working together was captured and went viral online, touching countless people. Netizens commented: "On his shoulders he carries his family; in his hand he leads the future." For over 40 years, he has trodden the stairways of Chongqing, using nothing but a carrying pole to support three children and an entire household.

Times may change, but some backbones never bend.
