Changyuyutian is located in the south wing of the Yangtze River Delta, southeast of Wenling City, south of Zhejiang Taizhou Bay. Due to the dramatic changes in paleoclimate, the multiple turbulence of the sea surface, and the rise and fall of neotectonic movements, the Quaternary in the Tianshan Mountains and the plains of Changyu Island have great differences in lithology, genesis and thickness. . Into the Changyu Haotian, the main thing is to visit the quarry cave and the overall orientation of the mountain. The body, the water, the cloister, put it in, feel the rocky scenery here, listen to the echoes in this mountain. The evening is narrow and the entrance is suddenly clear. A pool of Biquan is covered with a winding bridge with a twisting ring. The bridge has a stone carving big pearl, which is named after the Mingqu Pearl Bridge. All the way, the bamboo, the color of the mountain is different due to the erosion of water. If it is during the summer flood season, the amount of water will be much larger and it will be much cooler.
