Excuse me, how can I get to Polar Ocean World from Qingdao Railway Station? Which bus should I take and how much it costs to take a taxi. thank you

Sorry, I called from Pichai Yuan last time. It seems that the whole journey cost more than 20 yuan. We got off the bus when we were 0/00 meters away from the sea world gate/kloc-. Because there was a traffic jam, we strolled there, and it was especially difficult to take a taxi when we came back. We have to take two more taxis and have children. As a result, we took two stops to get a taxi. Moreover, if we take a taxi after four o'clock in the afternoon, the driver will pick up passengers selectively.
