hackneyed

1. ADJ If you describe something such as a saying or an image as hackneyed, you think it is no longer likely to interest, amuse, or affect people because it has been used, seen, or heard many times before. 老生常談的; 不新奇的

Power corrupts and absolute power corrupts absolutely. That's the old hackneyed phrase, but it's true. 權力導致腐敗，絕對權力導致絕對腐敗。這雖是老生常談，但無半點虛言。
