According to the recently released _Advertising Certification Content Enforcement Guideline_, the relevant authorities have issued a public call for comments. The guideline emphasizes that advertisements must not utilize font size reduction or other methods to provide supplementary explanations. Specifically, it states that advertisements containing information about the performance, functionality, purpose, specifications, expiration dates, and promotional conditions of goods cannot use font size reduction, font changes, or text colors that are similar to the background to make it difficult for consumers to discern. Furthermore, the guideline prohibits making unreasonable interpretations or explanations of the performance, functionality, purpose, specifications, expiration dates, and promotional conditions of goods.
