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. 老生常谈的; 不新奇的

Power corrupts and absolute power corrupts absolutely. That's the old hackneyed phrase, but it's true. 权力导致腐败，绝对权力导致绝对腐败。这虽是老生常谈，但无半点虚言。
