Known as the "world's first level" is

"The first pass in the world", namely Shanhaiguan, also known as "Guan Yu", is named after the ancient Chongqing water and is located about 1500m east of Tongguan. Facing the natural barrier of the Yellow River in the north and the source of Niutou Mountain in the south, it is the gateway of ancient Tongguan, with high walls made of bricks. The "First Pass" and "Golden Steep Pass" on the banners outside the door are full, round and powerful, both written by Aisingiorro Li Hong, the emperor of the Qing Dynasty. The pass is dangerous, and there are many roads on the plateau. You are only allowed to ride a bicycle and walk five miles to see the sky far away. When I entered the first village, I saw the east gate of Tongguan. Du Fu, a poet in the Tang Dynasty, wrote a poem "People look at the important place, can ride a bicycle on the narrow path, struggle for a long time, and use their husbands through the ages" to praise his risks.
