Health centers are unfamiliar to most people, and few people go there. Health centers are similar to pension institutions or hospitals, but the service items are different. The core of health center is to provide health services and comprehensive convalescent facilities to meet the comprehensive health needs of customer groups. The main customer groups of the health center are not only nursing staff received by nursing homes, but also patients received by hospitals, but customers who really need the combination of medical care and nursing-patients with chronic diseases. Health care and chronic disease management are the core business of health care centers.
