A unique cliffside bookstore nestled within a 326-meter-deep sinkhole in Hechi, Guangxi Zhuang Autonomous Region, has captured global attention for its breathtaking setting and innovative approach to the reading experience. Located in the Mianhua Tiankeng Scenic Area, the bookstore opened its doors in May and has since become a must-visit landmark. At night, the space transforms into a luminous ‘knowledge canyon,’ with over 10,000 books arranged along the cliff walls, illuminated by strategically placed lights. Reaching this literary haven requires visitors to navigate more than 1,000 plank-road steps, adding an element of adventure to the journey. The bookstore’s dramatic location and immersive atmosphere have made it a viral sensation, redefining how people engage with literature and nature.
