Bookstore inside 326-meter sinkhole becomes viral landmark

A cliffside bookstore in the walls of a 326-meter-deep sinkhole in Hechi, Guangxi Zhuang autonomous region, is drawing widespread attention for its dramatic setting and unusual reading experience.

After opening in May inside the Mianhua Tiankeng Scenic Area, the bookstore quickly became a landmark. At night, lights illuminate more than 10,000 books arranged along the cliff, creating what operators call a "knowledge canyon". Visitors must descend over 1,000 plank-road steps to reach it.
