Can the propaganda of the alma mater exaggerate itself?

You can't. When promoting your alma mater, you need to ensure that the information provided is accurate and true, and you don't exaggerate the facts. Publicity should not fabricate or exaggerate the achievements or reputation of the alma mater. This is because exaggerating or fabricating information will lead the public to lose trust in their alma mater and even damage its reputation and image. Therefore, when the alma mater promotes itself, it should show its strength and achievements truly, objectively and accurately.
