Under world

The rugged terrain as visitors approach Tiankeng Difeng is a hint of the extraordinary landscape that awaits them in this underground wonderland. Luo Wangshu and Tan Yingzi explore a unique spot in Chongqing.

Asinkhole nestled in the depth of mountains in Fengjie county, Chongqing, remained unknown to the outside world until a group of British explorers from the Royal Geographical Society stumbled across it in 1994. Its fame has been spreading all over the world ever since.

Acclaimed as a wonderland in Southwest China, it's called Tian-keng Difeng by locals - literally "the sky hole and earth cave".
