Leninism is the key link between theory and the practice in Marxism，as well as the direct source of the sinicized Marxism-Mao Zedong Thought. Without returning to Lenin's theory of imperialism，all major international phenomena in contemporary world cannot be thoroughly understood and well explained. Democratic socialism castrates the practical character of Marxism by removing class struggle between the proletariat and the bourgeoisie and the dictatorship of the proletariat-the inevitable result of the class struggle-so as to turn Marxism into a“universal”theory which may be accepted by the bourgeoisie. As a result，democratic socialism purported to be “non-violent ” at every crossroad in socialist revolution，and tightly clutched both hands of the proletariat. Democratic socialism in China attempts to shield people from

Leninism, especially from the method of class analysis and the theory of the dictatorship of the proletariat，so as to actually deprive Mao Zedong Thought of its spirit. When the “Mao Zedong Thought ” without the spirit of Leninism，together with the“Deng Xiaoping Theory”with “the four cardinal principles”removed，are used to paralyze the Chinese people，the effect will be the same as when “Marxism”without the dictatorship of the proletariat is used to explain the history of China's socialist revolution and construction，which will lead to the beginning of a major disaster for China and even the Chinese people. Democratic socialism as in the struggle with Marxism-Leninism will be the most dangerous factor in the cause of socialism in China，and therefore should be regarded as the new object of our resolute fight in the field of ideology.
