With the development of science and technology, high-tech toys such as sound, light, electricity and integrated circuits are mostly used in the modern children's toy market, and there are fewer and fewer toys that can make children really use their hands and brains to participate. Therefore, many modern toys are designed to "show the advanced nature of science and technology", paying attention to simplicity and convenience, replacing children's creation with adult technology, and children can only take the initiative in the illusory world, but they often seem at a loss in complex real life. Child psychologists point out that this is the negative effect of the change of social lifestyle on children's physical and mental development.

At the same time, the space of children's games is more and more restricted, so children's games are often in the relatively closed space of "concrete forest". Over time, they are getting farther and farther away from nature and lack opportunities to communicate with children around them. This will seriously suppress the full and free development of children's personality and make them fall into a cramped and narrow situation. Growing children are active, and appropriate outdoor sports games are very necessary for their growth. When children touch, climb, roll and run, they can improve their motor skills, exercise their will and quality, and form a good collective concept and anti-frustration ability. (from the network)
