Abstract: As a kind of sub-space, moral space is not only a man-made space, but also a human space, which includes the two-way dimensions of individual moral space and social ethical space. In the context of moral space, moral education is the process of construction, cohesion and flow of moral space. It is the backbone of clarifying the boundaries of individual moral space, condensing the consensus of social ethical space, and strengthening the two-way flow of individual moral space and social ethical space. However, in the current moral education, the dislocation of individual moral space, the dismemberment of social ethical space and the static suspension of individual moral space and social ethical space and other moral space crises are frequent, resulting in its construction being blocked, cohesion restricted and flow blocked. Moral education should respond to this, and rebuild the moral space where the mind and action go by taking care of life integrity, building a trust society and shaping the realization path of public morality.
