Plz let me know which hospital good for medical test for China work visa

Usually, you should go to the state-owned public hospitals to do the health examination. You can contact with the embassy of PRC and confirm which one you should go.
Based on what I know, you don’t need to provide the medical report when you apply for the work Z type. After you enter PRC with the Z type, you need to apply for the temporary residence permit, then the medical report is needed, and you should do the medical test at the International Travel Healthcare and Medical center.
