American wingsuit flyer Jeb Corliss has performed a jump and dive through a narrow crevasse in the Langshan Mountain in Quzhou, in east China's Zhejiang Province.

The 298m-deep valley is 20m (65ft) wide at its widest point and only 3.5m (11ft) wide at its narrowest point.

Two years ago he successfully performed a similar stunt through Tianmen Hole - an actual hole through a mountain in China's Hunan province.
