Running a hundred miles, everyone just wants to witness and experience this winding "art" highway.
From the foot of the mountain to the top of the mountain, it is not easy to count how many bends there are, because you will be completely immersed in this road when you walk. Everyone says that he has seventy-two bends, so it is called "seventy-two turns". It is absolutely a miracle of mankind to build expressways on mountains with complex geological conditions and frequent natural disasters. Behind the miracle is the blood and sweat of Chinese children. They gave up their comfortable and happy life and went through hardships, finally becoming seventy-two changes.
