Wunü Mountain (the Mountain of Five Women) is situated in the north of the town of Huanren, in Huanren Manchu Autonomous County, Liaoning province. According to legend, there were once five female soldiers stationed troops on the mountain, and therefore the mountain was called Wunv Mountain. It was once the birthplace of the Goguryeo nation. As one of the royal cities of the Goguryeo nation, the Huanren Wunü Mountain City is listed on the World Heritage List along with the Goguryeo ruins in Ji'an City, Jilin Province.

There is a thin strip of sky that is 31-meter-deep and has a narrowest width of 0.65 meters.Standing in the middle of it and looking up, you will only see a ray of blue sky. Reaching the Taiji Pavilion and looking at the distance, you will see the Huanlong lake hovering under your feet, shaping magnificent landscape.
