First of all, the inscription on the health education publicity column usually indicates that the publicity column was published by the propaganda department or organization. Therefore, if the publicity column is produced by a propaganda department or organization, then the word Xuan should be added to the inscription to show the propaganda nature of the publicity column. For example, the publicity column is made by a health bureau, so the signature can be written as "a health bureau announcement"
Secondly, if the publicity column is made by an individual or an unofficial organization, there is usually no need to add a statement to the signature. For example, if the publicity column is made by a doctor or a health expert, the signature can be written as "doctor system" or "expert group".
In addition, if you need to emphasize its propaganda nature in the publicity column, or want to highlight its propaganda function, you can also add the word Xuan to your signature. For example, the publicity column is used to promote a certain health theme, so adding the word "Xuan" to the signature can better emphasize its publicity function.
To sum up, the inscription on the health education publicity column should be judged according to the specific context and use. If you need to express the source and nature of the publicity column more accurately, you can add the word Xuan to your signature.
