A worth visiting attraction, a little far from the city of Shanghai, but the taxi was fast in the past, the cost was not very high, and it was acceptable. When we went, the weather was already very hot. The queue to enter the cave was a bit slow. It needed to limit the current. The cave was very cold and needed spare parts. It is really a hole in the sky, strange, all kinds of shapes of stones, with various colors of lights, there is indeed a beautiful feeling, very good!
