The average elevation is 96 meters, the main peak of E'cheng Mountain is 1196 meters above sea level, and the side peak of E'cheng Mountain is 1117 meters above sea level. The surrounding towns are huilong town and Tianshi Town in Kaijiang County, Tiansheng Town and Qili Township in Xuanhan County. Because there are more than 5, acres of natural forests and bamboo forests, it is also known as Echeng Bamboo Sea, which is a national AAAA-level tourist attraction and a provincial forest park. Through the two-way construction of Kaijiang County and Xuanhan County, Panshan Highway and Jianbu Mountaineering Road are now built on both sides. Most of the ancient buildings, such as the former hilltop ruins, are located on the huilong town side of Kaijiang County.
The peak of Echeng is a thousand miles high, steep and towering, stretching for a long time, winding to Daba Mountain Range. It was a post road leading to Xuanhan in ancient times, and it was called "the first pass to govern the west." In the Western Han Dynasty, "Hou Fan Kuai of Wuyang was stationed in Echeng, and the city was built in danger, and the site still exists". There is a trend of "and while one man guards it, ten thousand cannot force it". In ancient times, there was a saying of "West Emei and East Emei City". E'cheng Mountain can "view the clouds and the foggy sea, and the wonders are sudden; Listening to the pines under the moon, the empty valley echoes; Rain hits the bamboo forest, and the crisp sound is like a piano; The stream is ringing and the mountains are overlapping. " It is not only a summer resort, but also a natural oxygen bar. It is really a rare "geomantic treasure".
