Based on the theoretical foundation of historical materialism, Mao Zedongs thought about new person highlights the pursuit of value sources. Labor has been one of the most direct ways to return and enter into the nature for modern people. Molding new person is exactly to return to the life foundation and search for the life meaning through labor. New person has two sides of the same coin, i.e. one is the representation of self-decomposition and all things of being nothing, the other is the effort to pursue the meaning and rebuild the value sources. Therefore, the new person himself or herself has become the self-undertaker of value sources absolute person.
