Abstract: Recently, the phenomenon of “lying flat” of college students has aroused heated discussion in the society. How to correctly understand this phenomenon and guide contemporary college students to make unremitting efforts in the new era has become an important topic of research. Based on the analysis of the questionnaire data of 9,305 college students in 23 colleges and universities, the paper finds that the characteristics of “lying flat” of college students can be understood from four perspectives, namely, students’ willingness to lie flat, structure of the students lying flat, behavior of students lying flat and frequency of their “lying flat”. The paper also summarizes the psychological and social reasons for the phenomenon of “lying flat”. In view of this, the paper proposes that the phenomenon should be corrected from the aspects of social atmosphere, education and guidance, and mechanism construction, etc., to encourage contemporary college students to forge ahead to realize the Chinese dream of the great rejuvenation of the Chinese nation.
