It's beautiful! There is a feeling of walking in the underground palace, lamenting that nature is too beautiful, too magical! ___________ It also feels like an ancient tomb exploration. It's very big inside. You can only visit two-thirds of it for two hours. There are accompanying directors in the explanation. If you are not careful, you will lose them. Great journey, but not enough for the pictures, pit people! Developed photos of people, the image is not clear at all, the big picture needs 15, if they choose not, they put the photos into the garbage can very hard, like hatred! It feels bad!
