Video: Chengdu parkour enthusiasts show their stuff
The video shows the local parkour group Chengdu Underground displaying their stunts on camera.
Parkour participants use city structures, such as buildings, walls, stairs, and railings as obstacles to be surmounted via jumping, flipping, vaulting, and so forth.
The activity first appeared in China in 2006, according to Parkour Net and seems to have a small but organized following in the country, with groups in major cities sharing videos of themselves and hosting events.
