It's good. It's worth seeing. It's a bit crowded. Zhengzhou Ocean Pavilion is located at the intersection of Guoji Road and Zhongfangyuan Road. The main project of Zhengzhou Ocean Pavilion is divided into seven pavilions with one view per pavilion. Visitors can enjoy tropical freshwater ornamental fish in the Tropical Rainforest Hall, observe shallow sea coral reef fish in the coral reef hall, collect shells in the Marine Folklore Hall and weave fishing nets. The most amazing thing is that there is an undersea tunnel about 70 meters long in the undersea tunnel hall. When travelers walk in the tunnel, they can not only see sharks, rays and other large marine fish swimming around their heads, but also enjoy the large "mermaid" performance.
