Concept definition: From the sociological point of view, harmony is directly manifested in the proper coordination of interests in all aspects, which makes the social community in a harmonious state. As far as the education system is concerned, harmony is a balance of educational ecology, which involves at least two system elements inside and outside the campus. As far as the internal environment is concerned, it is reflected in the harmonious coexistence of educational subjects and educational objects on campus. As far as the external environment is concerned, schools should live in harmony with families and communities. As far as the essence of education is concerned, harmonious education is an education that suits children's nature and creates a suitable environment for the healthy development of every child. Therefore, we must change the concept from "children adapt to education" to "education adapt to children", pay attention to the development of children's subjectivity and the formation of independent personality, and handle the relationship between education and teaching. Harmonious campus is a school-running concept. The starting point and destination of all school work is for the harmonious development of people. Harmonious campus has clear direction, clear thinking, distinctive features and outstanding results in cultivating "four new" talents. Harmonious campus is a management mode. The core of this model is humanistic thought. No matter the school administrators, teachers or students, they can exert their greatest potential under its catalysis. Harmonious campus is a humanistic environment. In an honest, friendly, harmonious and energetic interpersonal environment, all people are respected and cared for. Every inch of the campus shines with brilliant humanistic light. Building a harmonious campus is not only a historical development process, but also a complex system engineering, which can be explored and practiced from many aspects and angles. But one thing is certain, the construction of a harmonious campus has five basic elements-the harmony of people, things, things, scenery and feelings.
