Bu is a redesign of a traditional Chinese folk cloth toy. It is both a toy that allows you to express your creativity and a teaching tool for learning Chinese folk art. Through magnetic attraction, different modules can be combined into different shapes. The surface of the modules is made of Velcro, so you can cut and stick fabric to create your own folk art. When used with children, it can stimulate their creativity and interest in folk art. Meanwhile, as a creative tool, artists from different backgrounds can combine their own styles and create distinctive works of art.
