Freedom, equality, justice and the rule of law are the contents of Marxism. Marxist values of freedom, equality, justice and rule of law bear nature of history and class, where freedom, equality and justice are not absolute, but relative; not abstract, but concrete. The rule of law is the result of civilization created by mankind and the basic way of governing the country. Marxist values of freedom, equality, justice and the rule of law are one of the ideological sources of socialist core values, which are realized through the socialist system. Socialism is the unity of value and system. The unity of socialist value and system is rooted in the inherent logic of socialism itself.
