In the mountains of China...

This is a construction scene of a road being built on a cliff, and it's frightening.I'm a total novice when it comes to construction, so I can't really explain it well.When I look at this construction site, I begin to feel an indescribable anxiety about common sense regarding structural mechanics, and even safety.A total of seven shots of the construction work.The photo in No. 5 looks like a completed concrete road, but I wonder how those thin rods can support the upper structure. I wonder if the concrete structure is made by drilling holes in the rock and inserting rebar. Still... something seems strange.Besides, why would they need to build a concrete road on such a rock face?Something's wrong. Dear workers, safety measures = 0 (zero) Anyway, it's strange.But... however...In places where they somehow manage to do something like this, There is something to learn!
