The reasons for the real name of Hai Fitness are that the submitted documents are not in compliance with the regulations, the identity information is inconsistent, and the system is out of order.

1. The documents submitted do not meet the requirements: ID card or other officially recognized valid documents are required for real-name authentication. If the submitted documents do not meet the requirements, the certification will not pass.

2. Inconsistent identity information: If the submitted identity information is inconsistent with the information registered on the platform, or the mobile phone number or email address used has not been authenticated by real name, the authentication will also fail.

3. System failure: Authentication failure is caused by system failure or network problems. It is recommended to try again later or contact the platform customer service for help.

4. Other reasons: There are other reasons that lead to the failure of real-name authentication, such as the adjustment of platform authentication rules and the change of authentication audit standards.
