Tianxingdong is in the middle of the Tianxing Scenic Area. Outside the stalactites in the cave, the sky is more than 20 meters high and long, and then I heard hundreds of people shouting. The voice was boiling. I know it was just the sound of water, but it was too scary. This is the pool. The water pool is the exit of the dark river. When it is called the water, the pressure of the volt current can be rushed up to five or six meters high. It is very spectacular. I only saw a trail closed. I was not allowed to go. The sound of adding water was too scary. I hurriedly took pictures and left. I don't know if it was right.
