In the Tang Dynasty, Pengyang ruled Baiquan County and built a city. In the Song Dynasty, due to the need of military garrison, the city wall was enlarged, forming the present pattern. In the Ming Dynasty, the buildings were abandoned, and Pengyang City suffered from disasters such as the earthquake of soldiers and bandits, and the city was ruined and gradually deserted and depressed. Although the town has disappeared, the momentum of the city wall still exists. In the past, there were temples on the mountains, also known as the western hills of Niangniang Temple.
There is another legend about the origin of Dengzhan Mountain. According to legend, at the end of the Qing Dynasty, a Hubei Feng Shui master named Zhao Mazi passed by Pengyang, but he saw a unique Western Mountain, with Lotus Mountain in the east and Aoshan Mountain in the north, forming a convergence of three mountains, and Ruhe River ran through the valley and flowed eastward. There is an ancient city on its mountainside, which looks like a lamp, and it is a rare place of geomantic omen. He said to the local people: Xishan is a cave of lights and the pulse of Pengyang's rise and fall. If the lamp is filled with oil, press the wick and the oil will enter the lamp booth, and Pengyang will prosper. People didn't know what to say, but the name of "Dengzhan Mountain" spread.
