Due to the excitement and risk factor of the projects, general playgrounds have age and height requirements for children for the sake of safety. As a result, many parents who want to take their babies to play are discouraged.

However, the Tianyuan Valley project in Qian'an has many choices and is safe. It is truly a playground open to all ages. It can be played by people from 99 to 99 to those who can just walk.
