Micro-plastic surgeons must have two certificates: Professional Physician Qualification Certificate and Professional Physician Registration Certificate before they can engage in the plastic surgery industry.

1. The qualification certificate for practicing doctors is issued by the National Health and Family Planning Commission after passing the national unified examination for practicing doctors and the qualification examination for practicing assistant doctors. It is a necessary certificate for medical practitioners in China, which belongs to the recognition of medical technology and proves that the holder has the skills and ability to engage in medical activities independently, and the certificate is permanent and valid (brown cover certificate). Those who apply for the qualification examination for practicing doctors are obtained through the qualification examination for practicing doctors held once a year. Certificate is also the most important criterion to judge whether a doctor has the qualification to practice medicine. The so-called "doctors" who have not obtained the qualification certificate of medical practitioners belong to "illegal medical practice".

The state implements the examination system for doctors' qualifications. The qualification examination for doctors is divided into the qualification examination for practicing doctors and the qualification examination for practicing assistant doctors. The unified examination method for doctor qualification shall be formulated by the administrative department of health of the State Council. The qualification examination for doctors shall be organized and implemented by the health administrative department of the people's government at or above the provincial level.

When obtaining the qualification of practicing doctor of integrated traditional Chinese and western medicine, he has the legal qualification of practicing doctor of integrated traditional Chinese and western medicine, and his qualification is valid for life. The qualification certificate for practicing doctors of integrated traditional Chinese and western medicine shall be uniformly printed by the Ministry of Health. The Certificate of Medical Practitioner of Integrated Traditional Chinese and Western Medicine is completely consistent with other types of certificates, and it is legal and valid anywhere in the country (except Taiwan Province, Hongkong and Macau).
