Zhu Chuanqi：Carrying Forward and Keeping Alive Engels’ Great Communist Spirit and Firm Belief

　　As a great Communist revolutionary, Engels had been fighting for the liberation of the working class since his youth. He was a great Marxist thinker and theoretician. He was not only a faithful friend of Marx, but also his lifelong collaborator. He made outstanding contributions to the establishment, improvement, and development of Marxist theory. Engels was a firm believer in communism. He fought and criticized opportunism and dogmatism throughout his life. Engels was a great man of high moral character and an open heart. He presented the praise and glory socialist activists and social organizations used to honor him for his 70th birthday as a wreath of honor to Marx’s grave. As we commemorate the 200th anniversary of Engels’ birth, it is important to carry forward and keep alive his great communist spirit and firm belief.
