The northern foot of the south, the southeast of Changning, and the Yiyishan stretching hundreds of miles from south to north. This mountain is not high, but the reputation is not small. According to legend, Emperor Shun visited the south and resting at the Jinlongyan in the mountains.

Deep Mountain Tibetan Ancient Temple. After the north of Bicui in the north of Shanbei, it was built in the southern Hunan Temple to the Holy Temple in the Qing Dynasty. At this time, walking in the mountains, more than a hundred miles of bamboo seas are endless, and the green bamboo leaves want to be dripping. The stone is on the Qingquan, and the seasons are inexhaustible, and the dingling sounds.

The beautiful scenery in front of Dayshan is easy to ignore the treasure under the feet.

Geological section shows that the Dayshan area was once a turbulent sea. With the crustal movement, the Yiyishan gradually raised from the bottom of the sea, forming the rock -soluble room formed. Geologists compare the surface here to a sieve, but the ground is a pot. There are many carbonated rock caves and leak water everywhere, like sieves; and underground granite and metamorphic rocks, no leakage, like a pot.

The sieve -like carbonated rock caves form a typical karst -landscape. In the Da Yishan Caishen Cave, stalagmites, stone pillars, stone cream, stone mantle and other strange states can be called "underground art treasure house".

The granite underground in the underground of Dayshan, due to a typical break, has created an important name in the geological academy -the Okiyama -style break. The names proposed by Li Siguang and Wu Leibo in 1948 refers to the breakthrough of the North and North West, which is generally developed in eastern China. The surface format format structure.

Under this unique land, there are rich mineral resources such as coal, tin, copper, boron, mercury, kaolin. During the Han Dynasty, Yiyishan began to establish Luanyuan Hall. During the Song Dynasty, the Yiyuan Milk Resort became a well -known mall in the country. In order to protect the ecological environment of the Yiyishan, mining is prohibited here in the 1980s and 1990s.

A good environment allows rare animals to gather here. There are three types of national first -level protection wild plants such as red beans, ginkgo, and Bole tree in the south. There are 31 national second -level protection wild plants such as Hongchun, and 19 national second -level protection wildlife.
