To understand the daily behaviors of the medical students, which could provide the guidance for medical students' study during their vacation, and enhance their autonomous learning ability.

A total of 960 undergraduates and postgraduates from a medical college in Hebei Province were surveyed to investigate basic conditions, sleep conditions, learning conditions, entertainment and sports conditions, and use the questionnaire star platform to design the questionnaire to collect data.

①During holidays, only 8.12% of medical students have poor sleep quality. There are obviously more master students with poor sleep quality than undergraduates. Undergraduates’ sleep disorder scores are higher than those of master students. Master students’ sleep time and sleep time scores are significantly higher than those of undergraduates. ②The ability of master students to learn independently during holidays is better than undergraduates. The scores of self-efficacy, learning control, learning significance, formulation of study plans and learning evaluation of masters students are significantly higher than those of undergraduates.③Medical students mainly use electronic equipment for study, undergraduates mostly learn professional knowledge through books (83.43%) and watching related teaching videos (72.93%), and masters study through literature reading (78.46%) and essay writing (56.15%); undergraduates learn English through memorize words (80.63%), master students mainly read English literature (59.62%), 78.44% of medical students listen to live webcast courses on time, but 51.39% of students think it is not as effective as classroom teaching. ④58.13% of medical students use electronic devices for more than 4 h of entertainment every day, no significant differences between different grades. ⑤Medical students who exercise more than 30 minutes a day account for 22.19%, of which there are significantly more master students than undergraduates.

The sleep quality of medical students during vacation is average, and the sleep quality of master students is significantly worse than that of undergraduates. The self-learning ability of master students is better than that of undergraduates during holidays; undergraduates and master students have different focus on professional knowledge and English learning. Undergraduates and master students use electronic equipment for a long time for entertainment every day. There are obviously more master students than undergraduates who exercise more than 30 minutes a day.
