Abstract: Justice is the fundamental feature and construction goal of a society ruled by law. In essence, the view of justice is one's understanding, judgment, evaluation and choice of "the deserved" of an individual or a group based on the principle of equality and justice, and under the premise of people foremost. The principle of justice in a society ruled by law takes equality as the premise, personal happiness and social justice as the goal, and it is mutually beneficial beyond justice and practical beyond ideals. The view of individual justice is constructed in the interweaving of independent internalization mechanism, environmental immersion and professional teaching. The cultivation of justice in the construction of a society under the rule of law needs to be based on the social field where humans, behavior and environment interact, and on the premise of transcending the "emotion ontology" in the social field; it should take the path of placing the group into the individual, activate the social identity mechanism of children, and promote the independent construction.
