NHS (National Medical Service System) is divided into three management levels, the first level is the basic community medical system, the second level is the community general clinic, and the third level is the city general hospital. Community clinics provide the most basic medical care services 24 hours a day. If necessary, the doctor will transfer the patient to a higher level hospital. Such a system has played an important role for a long time and was once advertised by the British as "the most perfect medical service system in the West".
