The whole process was amazing, although it was artificial, but it was also a great project, and rafting was also fun. Take the whole family to play, my parents said it was too beautiful and beautiful all the way. It is often a bit short to play, plus rafting, a total of 2 hours came out. But it is still worth playing once. Drifting is from the open air into the cave and the open air into the cave, the design is still very commendable.
