In ancient times, Chinese medicine had a relatively complete theoretical system and rich clinical experience, and doctors needed to pass strict examinations and practical experience to obtain medical qualifications.
Ancient medical practitioners were mainly responsible for providing medical services to officials, their families and officials. In official hospitals, doctors need to abide by certain rules and regulations, such as triage according to the severity of illness, and regulations and restrictions on drug use. Ancient doctors diagnosed diseases mainly by looking, smelling, asking and feeling, and prescribed corresponding prescriptions and treatment schemes according to the patient's condition. Doctors also need to pay attention to hygiene and safety in the process of diagnosis and treatment to avoid cross-infection and the spread of infectious diseases.
In short, in ancient China, practitioners were doctors who undertook official medical services. They obtained the qualifications of doctors through strict examinations and practical experience, and made important contributions to the medical service in ancient society.
