New largest caves discovered in Vietnam

Could be the world largest cave. The cave in the Annamite Mountains contains a river and jungle (its name translates to “mountain river cave”) and even its own thin clouds, and its end remains out of sight. It’s part of a network of about 150 caves in central Vietnam near the Laotian border.
