Introduction to Guilin Tiankeng: Guilin Tiankeng is a geological wonder that combines a karst cave and a tiankeng. It is currently the only karst funnel (tiankeng) in the Guilin Karst Tourism Scenic Area that can be entered on foot from the bottom. The whole tour starts with looking for "longevity". When you are in it, you can appreciate the exquisite pictures of the stalactite corridor in the cave, see the golden beaches scattered on the rock walls, look for the underground river basin connected to the Li River, and listen to the long and slow singing along the way. The sound of running water, breathing the green lungs of nature, and admiring the various rare species in the tiankeng in ancient times will make you feel like you are sitting in a well looking at the sky when you look up at the tiankeng. Take the elevator to the top of the tiankeng, look down, and feel the ghosts of nature. The outstanding creation of Shen Gong goes down the mountain along the way, returning to nature, surrounded by green trees, highlighting the charm of Guilin's landscape, and there are also health preservation methods to accompany you to the end of your journey to seek longevity.
