Adult tickets: Adults and children over 1.5 meters in height must buy full-price tickets to provide seats.
Half price for children's tickets: children with a height of 1.2 m to 1.5 m will buy children's tickets at half price and provide seats.
Free children: Children under 1.2m in height are free children, and must be led by an adult who has purchased an "adult ticket", and select "Yes" in the option "Whether to bring children under 1.2m". An "adult ticket" can carry at most one free child, and free children have no seats. When adults bring more than one child free of charge, they should buy half a child ticket for the extra children and provide seats for half a child ticket.
