Abstract: Objective　To explore the establishment of clinical mentor system to realize the continues diagnostic teaching model from the junior year to the graduation year, break the curriculum barriers and improve diagnostic teaching level.Methods　Medical undergraduates from Grades 2018 and 2019 studying at Shenzhen People's Hospital were selected as the subjects for the teaching reform. Various methods were implemented, including one-on-one clinical mentor system for guidance, reviewing diagnostic content after entering clinical practice, conducting diverse mini-lectures and clinical practice courses. The effectiveness of the project was evaluated through student questionnaires, interviews, and other forms to understand students' learning situations and achievements.Results　The survey results showed that most students recognized the value of continuous diagnostic teaching under the guidance of clinical mentors. Students thought that it was helpful to increase clinical practice opportunities, motivate learning enthusiasm, guide future learning direction, cultivate the habit of reading medical literature and the interaction with teachers after class.Conclusion　The diagnostic teaching model guided by clinical mentors promotes diagnostic teaching for medical undergraduates, stimulates their learning enthusiasm, increases opportunities for clinical practice, helps students enter clinical practice early, and has a positive significance in cultivating clinical thinking.
