I am not sure Iunderstand your question.
This place located at Shenzhen, China
Yes, Free entry.
Subway station Sea World Line 2
That's not even a question
Hi, firstly there is no entrance charge. It's not a theme park in that sense, but rather an entertainment area with 100's of restaurants, bars, cafes and a large ocean going yacht which is anchored in an artificial ''lake'' in the center of Sea World, and which is also an hotel, as well as has restaurants and bars.
If or when you're in Shenzhen, the subway is the best way to get there.
Sea World is on Line 2, and the subway is called Sea World Subway - the exits lead directly into Sea World.
Check this my tripadvisor page for my review on Sea World. I live next door to the place so I know it very well.
