When college students step into the society from the “ivory tower”，and walk from the campus to the workplace，they will experience a significant role change in their life，and become the major force in the process of socialist modernization. We need to pay attention to the basic situation and possible problems of their employment，personal life and mental health in this transformation process. Based on the survey data PSCUS of 2019 and 2020，this report analyzes the employment，personal life and psychological status of Chinese college graduates. The study found that the COVID epidemic had an obvious impact on the employment of college graduates. The proportion of college graduates working in the government and state-owned enterprises increased and the proportion of working in private enterprises decreased. There is still a considerable gap between the actual salary and income expectation of college graduates. A considerable proportion of college graduates show the worry of unemployment and the phenomenon of “job hopping” is quite common. The job satisfaction of college graduates is generally low，especially with low satisfaction on income level and professional reputation. The housing problem of most graduates is relatively prominent，and the living quality is relatively low. College graduates face great pressure and prominent mental health problems. College graduates are important human resource for the country，and government should actively pay attention to the problems faced by college graduates，help them solve practical difficulties and promote them to actively participate in the construction of the country’s modernization.
