It's really cool to come here in this hot summer. You can feel the cool air out of the hole in front of the hole. It's still cold to wear a sunscreen. Because there was almost no one in the cave on Monday, our old couple felt a little awkward. The strange-shaped stalactites in the cave were shocking. One fork by one small hole also gave us the spirit of young people's adventure. I have made an appointment with my friends next time, everyone will come together and have a good time.
