Why can't the video number send medical-related videos?

No certification.

In order to protect users' interests and ensure the safety and reliability of platform information, Tik Tok only allows public hospitals above Grade II, self-operated departments of public 3A hospitals, some units of national associations, provincial branches of subordinate first-level specialist associations, medical media and other institutions to carry out certification. Individuals such as vice president, deputy director of department, attending physician and above experts of public 3A hospitals hold certificates. Institutions and individuals outside this scope temporarily do not support certification.

Tik Tok upgraded the certification process and conducted an annual qualification examination for medical authors. After two notifications, some accounts still failed to supplement the certification materials within the specified time, and these accounts have been cancelled because they do not meet the latest certification requirements. The account that cancels the authentication will be restricted to use the doctor's nickname and introduction, and will also lose the qualification to publish medical and health content. If you want to continue to publish medical content, you need to supplement materials for certification.
