Aerial footage shows China's notorious mountain tunnel carved by 13 men with bare hands

This might be one of the most dangerous yet breath-taking car journeys in the world. A new drone video has emerged showing the dangerous mountain tunnel chiselled out of a vertical cliff in Taihang Mountains. The footage, posted to Youtube by CCTV News yesterday, is believed to capture the awe-inspiring Guoliang tunnel in central China's Henan Province. The formidable Guoliang tunnel was hand-carved by 13 men from an ancient village perched on top of the cliff at an altitude of over 1,700 metres (5,500 feet). The 1,250-metre-long (4,100 feet) passage is the only way to drive to the 600-year-old Guoliang village, which perches on top of the 200-metre-tall (656 feet) cliff.
