Stunning and bizarre photos from China have uncovered the latest training and promotional techniques of aviation schools as a group of flight attendants went through etiquette training courses on a 180-meter-high terrifying glass-bottomed bridge in Central China's Hunan Province.

Dressed in formal white and pink uniforms, the young women were being trained to have a good attitude and manners as they looked to toughen their determination.

The "Bravery training" was composed on China's first glass-bottomed bridge, hovering 180 meters above the valley floor in Shiniuzhai National Geological Park in Hunan Province.

Stretching 300 meters between two rocky peaks, the glass-bottomed bridge is aptly named Haohan Qiao meaning "Brave Men's Bridge" in English.
