Standing on the observation deck, the majestic view of the Taihang Mountains is unobstructed. Feel the fresh air, the trees of the mountains, the blue sky, the cool autumn wind, the rolling hills, the floating clouds, and a magnificent landscape painting. Thin knife peak is the main peak of the Dabie Mountain. Wollongong is the main peak of the thin knife peak. It is shaped like a dragon's back and has a tough edge. On the hills, a winding road from north to south has to pass through the heroic Guan, the beauty gate, the emperor, and so on, if you walk on the thrilling blade. It is not an easy task to get on Wollongong. It is recommended that friends with poor physical strength rest more along the way. Climbing to the top of Wollongong, I saw the wind and the mountains, the fog and the misty, magnificent. It makes people's life "will be the top of the mountain, the list of mountains and small" heroic.
