The Great Wall on the Cliff
For the convenience of climbing, steps was built on the wall. Even though, it is still hard for visitor to make it to the top through the 400 steps. But it is worth the painstaking efforts when visitors look afar on the top. The scenery is peculiar: the deserts extending to the horizon, with a few oases in it. People feel isolation and detachment from the noisy cities at first. They also feel the liveliness when they see the oases. Under such harsh natural conditions, people struggle to live on generation after generation.
