China's fourth "forest oxygen bar" list, a reference to places with plenty of trees, was recently released. CGTN will be reviewing 10 of the 22 listed forest parks. Today, we travel to Liping National Forest Park in southwest China’s Guizhou Province.

Located in Liping County of Qiandongnan Miao and Dong Autonomous Prefecture in Guizhou Province, Liping National Forest Park covers an area of 4,573 hectares. The forest coverage rate here reaches as much as 94.5 percent and most of the forests sit at an altitude between 500 to 1,256 meters.

A subtropical monsoon climate with an annual average temperature of around 16 degrees Celsius, the park is a pleasant place to visit all year round.

Besides boasting abundant natural resources, Liping county also holds four Guinness World Records:

In 2001, Zhaoxing was included into the list of Guinness Book of World Records for Zhaoxing Drum Towers and Dong villages. Zhaoxing, the largest Dong ethnic town in China, boasts the largest Dong drum tower complex in China.
