Dong Hui and Li Jiali pointed out in the sixth issue of world philosophy in 2020 that paying attention to the emotional alienation of people in digital labor is the proper dimension to reflect on digital labor. Digital labor includes the process of creating digital identity, production data and consumption data. In this process, people's true feelings become the product of dissidents. Firstly, digital identity abstracts the real human perceptual life into a series of symbols; secondly, the emotional needs of individuals as data producers and consumers are alienated into the false desire for countless symbols; finally, the privatization of people's data by data platform results in the difference between individuals as data producers and the nature of free labor. At present, it is possible to promote people's emotional liberation in digital labor by improving the system and norms of digital labor, cultivating social emotions with socialist core values as the core, establishing the spirit of data sharing, and building a digital community.
