Tickets are issued quickly, but the ticket exchange guidelines are not perfect, and you still have to queue at the ticket purchase window. There is no self-service ticket exchange machine, which caused a lot of time to waste in the wrong queue. The security guard responsible for queuing in the aquarium team is not very good at English, and I don't know the business of ticket exchange. I was in line for a long time, and I had to go to the ticket window again. Recommended,
