A lot of people. We didn't queue when we entered the gate because we bought tickets from the roadside for passengers. There was no discount for 190. But we got tickets from Huangdao to the railway station for free and then to the Polar Gate (a long journey). We got tickets from D entrance without queuing. It seems to me that we bought tickets and some travel agencies brought tickets from ABC entrance. There are a lot of people in the queue. When we finally got to the Dolphin Show Hall, there were the most people in the queue. We lined up for the performance at 14:10 and started at 13:00. There were already a large number of people in front of us. There were so many people in the queue that the shark passage was basically submerged. In the morning and noon, most of them are travel agencies. In the afternoon, there are fewer people. Because many people come out of the polar region, and then go to the Olympic sails in the afternoon when they return, and then to the May 4th Square... This is a route. But if you want to go to the old man, you need to walk ten minutes further from the polar region. Feed Moby Dick 100 times, you can go to three people. Feed the sea lion a meal of 30. Feed it outside the fence. We stayed in the museum for two and a half hours even when we were waiting in line for the dolphin show.
