Pre-job training before internship is the need to adapt to environmental changes, and it is also the need to clarify work requirements and goals. Pre-job training includes introducing the general situation of hospitals and laboratories, understanding the composition structure of various departments, division of labor and distribution of personnel, configuration of instruments and equipment, and organizing the study of hospital rules and regulations and personal medical protection. In addition, we should pay attention to professional ideological and moral education, establish a good medical ethics, abide by professional ethics, develop a meticulous and rigorous work attitude and pragmatic work style, and enhance the sense of responsibility and mission.
