Southwest China's Guizhou Province is the second stop of CGTN's livestream: What's up! China. Located in Libo County of Guizhou Province, Maolan National Nature Reserve is known for its spectacular karst landforms.

On April 22, World Earth Day, we embark on a journey to explore the karst landforms and get in touch with nature. The karst caves and rocky forests paint us a picture of humans living in harmony with nature.
