With the development of society， the number of people suffering from psychological disorders is increasing. Due to the lack of knowledge in psychiatry， most of the patients turn to the general hospitals. There may be a considerable number of missed diagnosis. Consultation-liaison psychiatry has developed and improved gradually， and it is of great clinical significance to explore a consultation model suitable for China's specific situations. As the consultation-liaison psychiatry service is for patients with psychological problems in the general hospitals， the level of required professional skills is higher. The service mode of consultation-liaison psychiatry， the development of the consultants， and the effectiveness of consultation-liaison psychiatry are worthy of further discussion by clinicians.
