The paper analyze it from these aspects: Firstly, in the communism, when the survival necessity and feast necessity are satisfied enough, the self-fulfillment necessity will become the most important necessity in people's life. The freedom labour is in the course of self-fulfilling. Secondly, the"truth""good"are united in the labour , which make it possess the nature of beauty. Thirdly, in the game, people disremember the outside bondage and enjoy the happiness and freedom. Compared with the game, the freedom labour has many same characters and is more fascinating. Finally, the labour and the people's development have many affinities: In primeval, the autonomic labour was corresponded with the people's"primordial enrichment". In private owned society, alienation labour was corresponed with the people's macrocephalic development. In the communism, the freedom labour will corresponded with the all-powerful development. The development of human history incline to the trend that history makes everyone develop all-powerfully, the freedom labor will be the final choice.

真正自由劳动所具有的特质，将使其成为人们生活的第一需要：(1)从需求的层次性看，在未来社会，当生存的需要和享受的需要得到满足之后，自我实现的需要将成为人们生活中最重要的需求，而真正自由的劳动就是自我实现的过程；(2)真正自由的劳动在于真、善在劳动中的统一，使得劳动具有美的性质；(3)在游戏中，人们忘却了外在的束缚，得到快乐和自由的体验；较之游戏，真正自由劳动具有诸多相同的性质，将更加引人入胜；(4)劳动和人的发展有着密切的关系：原始时代的自主劳动对应着人的发展的"原始的丰富"；私有制时期，劳动的异化对应着人的发展的畸形、片面；到了共产主义社会，自由劳动将对应着人的自由全面发展。
