Second, the improvement of residents' health awareness has expanded medical care expenditure. Thirdly, the COVID-19 epidemic has raised the health awareness and needs of all people. Fourth, environmental pollution has increased the health care needs of residents. Fifth, policies promote the construction of a healthy China.
