The concept of fairness and justice has evolved from the concepts of individual deservingness to social fairness.In Xi Jinping Thought on the Rule of Law,the theory of Social Fairness and Justice is a composite concept of justice that not only integrates the individual and society,but also transcends individual deservingness and social fairness.It is the shared justice system for all members of society,which is based on personal striving,and economic and social development,and is fundamentally aimed at common prosperity,representing the pursuit of the ultimate value of socialism.The theory of Social Fairness and Justice in Xi Jinping Thought on the Rule of Law,surmounts the traditional fairness and justice which simply focuses on the distribution of interests and resources.It extends its tentacles to every corner of social life and embeds it in legal practice.In the construction of the rule of law in China,legislation should aim to promote social fairness and justice,and ensure that members of society have the same qualifications,powers and functions as well as pay attention to the inclined protection of the weak;law enforcement must take fairness and justice as the criterion,and treat all members of society fairly and justly in administrative actions;judicial justice should be the final defense line to safeguard social fairness and justice,and strive to make the people feel fairness and justice in every judicial case.
