In addition, due to the need of epidemic prevention, Nanjing Medical University is likely to start classes in batches this year to avoid a large number of students gathering. Please pay attention to the relevant information released by official website of Nanjing Medical University in time for the final schedule. Because of the epidemic, many schools can't start normally, so everyone should be considerate, less anxious, listen carefully at home and pay attention to their health.
