The tree of wisdom was founded in 2003. The program embodies the scientific educational concept in vivid games in a lively form, so that children can learn and grow up healthily in the games and create classic educational programs for preschool children aged 3-6.

The program "Tree of Knowledge" has several program sections, which are arranged in a magazine that conforms to children's psychology. The five sections, including handicrafts, magic, science, food and parent-child games, are broadcast from Monday to Friday 17:00 respectively. The column is dedicated to becoming an "air kindergarten" for preschool children. The program system is based on the advanced educational theoretical framework of "five games and eight wits", and helps children grow up with the program content of "entertaining".
