Self-identity is multi-dimensional instead of uni-dimensional. We can not only employ one of the facets of self-identity to measure it as a whole. Work is definitely one of the categories of self-identity but it is not the only category to identify people themselves. Even if we don't discuss the psychological elements on this issue, from the perspective of sociology, self-identity is also closely related with education, culture, ethnics and so on. In this essay, we only correlate the issue of self-identity in the context of relating education with work. Although either education or work is seen as the separate category of self-identity, in practice, self-identity is achieved through the collaboration and mutual effects of education and work due to the close relationship between the two of them. Therefore, education, as the base and threshold to work, "life long education" and cross-disciplinary knowledge education should be promoted in order to help people establish the positive self-identity.
