Introduction to stalactites: Walking on a floating bridge across an underground river, with neon lights like stars and strange rocks, being among them is like walking into a mysterious space. Crossing the underground river, the stone walls are intertwined with ancient vines, stalactites of different shapes, and the cool breeze blows. It is a good choice for people who have lived in the city for a long time to relax and listen to the call of the soul in the Yangyang River.
