Located in the low lands between the mountains of Changning and Jiang'an counties, Shunanzhuhai (Sea of Bamboo of Southern Sichuan) was originally known as Wanling Gully. The 28 mountains have more than 1,000 peaks, each blanketed in bamboo. In addition to the more famous Nanzhu Bamboo, there are more than 30 different varieties of bamboo growing in the 4,000 hectares of Shunanzhuhai.
