Abstract: To cultivate the socialist builders and successors with all-round development of morality, intelligence, physique, aesthetics and labor is a key aim of fundamental education in China. As an important part of school culture, "wall culture" should realize its invisible cultivation functions in the following aspects: to focus on the essence of the school’s culture; to help teachers and students establish a consciousness of all-round development; to facilitate the educational activities targeting students’ all-round development. Empirical analysis identifies several practical barriers hindering the functions of "wall culture": emphasizing more design over refinement, emphasizing more publicity over education, and emphasizing more adults over children. The "wall culture" should be rooted in the school’s operational features, teaching activities and student activities to realize its function of promoting students’ all-round development.
