Individuals should obey the whole, and individuality should be integrated into the collective. "Self" refers to an individual, emphasizing his interests, needs and personality. "Big ego" refers to the collective and the whole, emphasizing the interests and needs of the whole. Individuals should obey the collective in action and thought and serve the interests of the collective. At the same time, individuals should also find their own value and position in the collective, and make contributions to the collective while realizing their own value. "Individuality dissolved in commonness" means that the individual's individuality should be integrated into the collective to serve the collective's goals and needs. Individual personality and characteristics should be displayed and embodied in the collective, and also need to be adjusted and run-in in the collective. Only in this way can we achieve a win-win situation for individuals and groups.
