余生未了庸人自扰
[yú shēng wèi le yōng rén zì răo]
Interpreting 'Yu Sheng Wei Liao Yong Ren Zi Rao': It means something left undone in remaining life and a common man troubles himself needlessly. In short, this expresses self-reflection or regret over unfinished tasks, and anxiety brought upon oneself without any real necessity during rest of his life.
