Although it was not the first time to go to Wuyishan, it was the first time to climb the essence of Wuyi Mountain: Tianyou Peak. Tianyou Peak is made up of a huge rock, known as the first megalith in Asia. On the stone wall of the peak, three strong characters "First Mountain" were engraved, which was written by Xu Qingchao, the general of the Second Emperor of the Qing Dynasty, in 1832. The entire Tianyou Peak is a natural observation platform. The Jiuqu River surrounds the foot of the mountain. During the mountaineering process, the tourists are bowing to the meandering Jiuqu River. The bamboo rafts of the two and three are flowing down the mountain. The waters are beautiful, the mountains and rivers blend together, like a Chinese freehand ink painting, beautiful.
