The altitude of main peak Mingwang Peak is 289.5 meters and there are bog swamps on the top of the mountain. There are lots of geese inhabiting here in autumn and the North Yandang Mountain is relatively overlooking with it across the river so it is called South Yandang Mountain.

　　

　　The South Yandang Mountain was originally divided into Dongxi Hole, Shun Stream, Chou Stream, Rock City and East Lantau five scenic areas and there are 67 peaks, 24 holes, 13 pools, 8 waterfalls and 9 stone.

　　　The development of South Yandang began in the middle Tang Dynasty, flourished in Five Dynasties and two Song Dynasties. When the tang clan Li Gao was the chief of Wenzhou, he once wrote the poem "Visiting the South Yandang Mountain ". During the Five Dynasties, The monk Yuanqi settled down here. The king of Wu Yue Qian's said "because of the construction of the Puzhao Dojo, he used the Fu of whole Pingyang to praise it." In the Northern Song Dynasty, Huiwen Pavilion was built and it was called Huiwen School.

　　 "The South Yandang Mountain" by a human being of Ming Cai Fang wrote that ”East Ou Yandang is a famous mountain in the world. There are two mountains and its south mountain become famous earlier. " The development history of South Yandang Mountain can be traced back to the earliest of the Southern Liu Song Dynasty period of more than 1580 years ago, when the ancestor of Chinese landscape poetry Xie Lingyun was the chief of Yongjia, he once went through Lingmen Mountain of Pingyang County(wrote a poem called “Visiting the Lingmen Mountain”) and visit the now Red Rock Scenic Area of South Yandang Mountain. The poet of Qing Dynasty Zhang Qiwu had a poem to remember: " I want to catch up the footsteps of Xiegong where to enjoy the journey. Gardenia flowers opens everywhere and banana forest is full of Red Rock Mountain."

　　

　　　　In 771 (6th Year of the Tang Dynasty), Li Ting of Wenzhou and other people went into the mountains to cut firewood and lost their way, then they found a place of paradise. The poet Tang Dynasty Gukuang had a detailed description in the "fairy tale".

Many monks came and went, they said happily that it is the most beautiful scenery in the world lived by Long Yan. Is it not the western book is called the Nuo and the dragon is the one who flies said by the western book? So he live here." In the meantime, the king of Wuyue gave him money to fund his construction of 18 nunneries such as Puzhao Dojo in the Southern Yandang Mountain.
