If a legal person is required to sign, only the "legal representative" of the "legal person enterprise" can sign.

The "license manager" and "clerk" authorized by the legal representative cannot sign.

A legal person does not need to register or enter a user name and password to log in. Click on "legal person login portal".

After successful login, if there is something to sign under the name of the enterprise, but the role of the login person is not "legal representative", there will be a corresponding prompt, and you need to log in with the "legal representative" of the enterprise.

Click "User Center" to log in successfully, select the list of enterprises to be signed, and click "Sign up".
