2. Personal nicknames are not allowed to authenticate corporate accounts, such as the chairman of xx company and the CEO of xx company.

3. Short video nicknames are not allowed to be repeated, and enterprise certification is based on the principle of first come first served, so enterprise certification should be applied as soon as possible.

4. Nicknames with broad nicknames will not be passed on.

5. Nicknames should not use common words alone. When the enterprise name/brand name/product name/trademark name is a common noun, it must be suffixed, such as xxAPP, xx website, xx software, etc. Otherwise you can't pass the exam. If the trademark name is "red envelope" and the business scope is catering, it should be "red envelope catering".
