Quality education is characterized by integrity, comprehensiveness, foundation, cooperation, development and future. Among them, wholeness is the most essential provision and the most fundamental requirement of quality education. Broadly speaking, the so-called "all" means that quality education must be geared to all the people, and any member of society must receive a certain degree of basic education for a certain period of time through formal or informal channels. In a narrow sense, all school-age children receive formal basic education. The so-called "development" is to focus on cultivating students' knowledge and ability of self-learning, self-education and self-development, and really shift the focus of students to enlighten their minds, cultivate their potential and enhance their stamina.
