You must visit the Yardang Geological Park to experience the feeling that you are the only one left in the whole world

There is a Yardang landform on the Hexi Corridor! Here, 700,000 years is not just a flick of the fingers, it is the years of erosion by wind and sand. About 90 kilometers west of Yumen Pass in Gansu, there is a typical Yardang landform community. It stretches about 25 kilometers from east to west and is about 1-2 kilometers wide from north to south. When the wind blows, ghostly howls can be heard, and those who travel at night may find themselves unable to leave, which is why it is commonly known as the 'Devil's City'. The whole area resembles a medieval ancient city, this special 'castle' has walls, streets, buildings, squares, churches, and sculptures, all vividly and exquisitely crafted, astonishing the world. These masterpieces of nature are truly awe-inspiring and infinitely wonderful.
