Amusing footage from north-central China of a tourist petrified by a glass-bottomed bridge that spans the mighty Yellow River.

The video, filmed in Ningxia Hui Autonomous Region on August 11, shows the desperate woman lying down and crawling along the mere 10-metre-high bridge.

In the video, she can be heard screaming at her friend: "What the hell is this? How can I survive? Why don't you help me instead of taking pictures?"

The bridge is 210-metre-long and 2.6-metre-wide, according to reports.
