How to join the medical aid team in Hong Kong?

You can apply to the health department.

Foreign aid medical teams are selected by the health departments/bureaus of all provinces, municipalities and autonomous regions among the middle-level and above medical personnel in the areas under their jurisdiction. The principle of selection is the combination of individual application and organizational recommendation. Examinations and interviews were organized by the health department, and it was finally determined that people should be completely closed for half a year before going abroad.
