Because my son likes marine life very much, so every time he goes to a strange city, the ocean hall is the place to be. So with a lot of experience of visiting the ocean hall, Guiyang's ocean hall is a polar series. The quality of the ocean hall in the polar region is still guaranteed. Moby whale, Mermaid show, dolphin show and Russian synchronized swimming are all very impressive. Rainforest design is also a highlight when entering the museum. Shortcomings - Russian synchronized swimming repeats, Mermaid performance for the first time, but to see them again in the dolphin hall will be a little distracted! The undersea tunnel is not very long and not bright enough. Others are OK!
