ساخت یک مسیر پیاده روی توریستی دور کوه شیفو در چین که به علت صعب العبور بودن منطقه، نیاز به کار خطرناک و طولانی مهندسان و کارگران دارد.

ببینید مراحل اینکار به چه شکل بوده است:

Workers build a footpath around the vertiginous slopes of Shifou Mountain in China
Thousands of metres up the vertiginous slopes of Shifou Mountain in Hunan Province , China , a team of workers, operating with hardly any safety measures, are building a footpath

The workers are building a plank road on the side of the mountain that, once it is finished, will stretch for 3km (9843 ft) and be China 's longest sightseeing footpath

48-year-old Yu Ji is one of the workers and he has been working on high cliffs building such plank roads for more than 10 years. 
He comments: "Young people don't want this job, as it requires them to stay deep in the mountains for months or even years"
