Actually, it's still fun. You can have an annual card in Hefei. On Saturdays and Sundays, there seem to be four dolphin shows, three families, girlfriends and couples. The last dolphin show started at 10 o'clock. My friends and I didn't catch up with the Shanghai dolphin show at the jellyfish resort. You can ask about the time of dolphin show in advance, and be careful to miss it!!
