Going by car on the weekend. Overall good, when I went through the cave parking lot, I didn't see the big brand, so I continued to walk for about three kilometers. I found out that it was wrong when I went to the end. I asked people and returned. The entrance to the hole was smooth and the ticket was convenient. After entering the hole, a staff member came to explain to us. Later, I said that I had to charge 50. I think this stone didn't listen to it, so I didn't want it. But this explanation is best to explain the charge as soon as it comes up, so as not to make an unpleasant end. Overall, it’s okay, you can come and see if you haven’t seen a cave.
