Located in Leping village, Huaxi district, Guiyang of Southwest China's Guizhou province, Yelang Valley has been built by Chinese artist Song Peilun. 

Song designed and built a stone castle in the barren forest with the theme of Nuo opera's facial makeup, masks and characters, and the materials of stones, pottery pieces and pots that can be seen everywhere, based on the local mountain shape, river direction and its original state.

Yelang was the first state in Southwest China established by the ancestors of ethnic groups, and was once wealthy and powerful in the region in history, rich in natural resources and regional cultural characteristics.

The territory of the state was limited. However, the king of the state was not aware of it, and made a fool of himself by asking the emissary from the Han Dynasty (206 BC-220 AD): "The Han and the State of Yelang, which is bigger?" The later generations use Yelang to describe a person who is ignorant and arrogant.

The state lasted for about 300 years and was destroyed in around 27 BC. But the culture of the Yelang lived on. The valley in Guiyang makes it reappear.
