A one-day tour in the local delegation newspaper, including Blue Mountain and this stalactite cave in Jean-Roland, is about an hour's drive away from Blue. It's quite shocking to see it. The painters of nature can be regarded as masterpieces. Unfortunately, my English level is not good. Although I follow a Chinese tour guide, I buy tickets and go to the cave. I will send an English guide to introduce the history and origin of the cave. What impressed me most was the design of a tap. I sent a picture.
