The outdoor playground is designed for the characteristics of children who like to play, climb, roll, and play, such as swings, slides, climbing walls, merry-go-rounds and other equipment, so that children can speed up blood circulation, promote metabolism, exercise, and promote growth and development in the process of playing. 
    Children playing in the outdoor playground can encourage children to use their senses to contact the world, such as stimulating their sight, hearing and touch, and help them cooperate with the responses of various senses on their bodies to contact and recognize new things in the outside world. Some tools make sounds, while others are designed with bright colors and attractive lines, which can directly bring visual stimulation to children. Different educational wooden toys are effective tools to help children understand the world.
