Dinghu Peak is the core scenic spot in Xiandu. It is like a bamboo shoot, towering into the sky. It is 170.8 meters high, with a flat at the top of the peak, which is 710 square meters. The Dinghu Peak is regarded as the No. 1 Peak and No. 1 Bamboo Shoot in China. There are pools among the forests, which are never dry all year round. It is said that the peak is the place where Yellow Emperor became an immortal. The best place for tourists to appreciate the scenery of Dinghu Peak is Yangzhi Pavilion. It is constructed during the Ming Dynasty and rebuilt later. The pavilion at present is with skirt roof and 12 pillars, which is of primitive simplicity and elegant. Next to the Dinghu Peak, there is the Tongzi Peak, which is 40.7 meters high. People always called it little stone bamboo shoot because of its shape. Half way up the peak, there is a round cave, which is like a navel. The Tongzi Peak is just at the same level of the cave, and seems as a child leaning close to a mother, hence the name of Tongzi, which means small child.
