Real labor is a kind of free labor instead of alienated labor,conscious labor instead of merely in-stinctive activity and creative labor instead of simply repetitive labor.It is the value creation and self-realization based on toil and pain,so it brings people the joy of labor.However,in real life,people are often annoyed by labor because of its hardship,inferiority and bondage.Marx comprehensively and systematically explored the source of labor annoyance-alienated labor-from four aspects:labor,labor products,the class nature of la-borers,and the relations among laborers.The goal of labor education is to educate students to experience from the annoyance of labor to the joy of labor,and to be willing to work.
