OCT Bay Water show in Shenzhen

I am planning a day trip from HK to SZ. Plan to see Folk village and Cultural Center in the morning.
Go for shopping at Harbor Happy Mall.

I want to see the OCT Bay Water show. How to reach there ? The show starts at 7:40 PM. Is the metro stop is OCT East on Luobao Line ? or is it at Damisha I am confused between the two as the Damisha can not be reached by the subway.
