In our educational activities, it is very important to create a theme wall that can really make children like it, interact actively and promote their active development. The Guiding Outline of Kindergarten Education clearly states that "the environment is an important educational resource, and the development of children should be effectively promoted through the creation and utilization of the environment". Therefore, it is particularly important to build the theme wall of children's development with the theme of "children's development". Valuable theme walls stimulate children's senses of lines, shapes, colors, composition and other factors, and bring them a sense of pleasure emotionally.
