2. No counterfeiting: a trademark cannot be counterfeited or confused with consumers, that is, it cannot be similar to an existing trademark or other people's business logo, so as to cause confusion, misunderstanding or association.

3. Do not violate public order and good customs: A trademark cannot violate public order and good customs, and cannot contain illegal, obscene, offensive or deceptive elements.

4. Non-misleading: trademarks cannot mislead the public, that is, they cannot provide false or misleading information to consumers, including misleading the nature, quality and origin of goods or services.

5. Non-infringement of others' rights and interests: A trademark cannot infringe on others' trademark rights or other intellectual property rights. Before trademark registration, it is recommended to conduct a comprehensive trademark search to ensure that the applied trademark will not infringe upon the rights and interests of others.
