how to get to ocean world and 7 wonder in guangzhou ?

As I know, there are several starway hotels in the city. Do you refer to the one located at No. 422 East Huanshi Road?If yes, from the hotel, you can walk to Ouzhuang Station to take the subway line 5 to Dongwuyuan (Zoo) Station. Take the Exit B, you will see the zoo, and the ocean world is located inside.
As for the 7 wonder you mentioned, would you like to provide more detailed info about it, for I fail to locate it.
