It is very convenient to enter using the QR code. Hong Kong tourists using discount tickets need to show their Home Return Permit. There were quite a lot of people there before the 51 holiday, and you need to arrive 20-30 minutes early to reserve a seat for the show. Most people need to sit on the floor to watch, but be aware that there are air conditioners dripping in many places. There are many marine creatures, including fish, corals, dolphins, beluga whales, Arctic foxes, Arctic wolves, sea lions, seals, walruses, etc. They are all in good condition. The lighting used is basically white light, so you can see the animals clearly. Unfortunately, there are relatively few scenes in the tank, so it looks rather monotonous. The performances were all wonderful. I recommend the mermaid show, the beluga whale show, and the polar flight (the 4D cinema is highly recommended!). Both theaters were wonderful.
