Two-thirds of the world’s more than 300 sinkholes are in China, scattered throughout the country’s west - with 30 known tiankeng, Guangxi province in the south has more of of them than anywhere else. Its biggest and most recent find was two years ago: an ancient forest with trees reaching as high as 40m (130ft). These cavities in the earth trap time, preserving unique, delicate ecosystems for centuries.
