Second, it is built in cities, and the infrastructure and supporting facilities are more convenient than in rural areas. Only a large and good general hospital can operate. Third, the city has high-end technical resources such as medical research institutions, medical universities and medical research rooms concentrated in the city, which are closely related to hospitals and can well support hospital technology.
