You don't have to ask for a thousand years. What do you mean?

The whole sentence is: know yourself and know yourself, not seeking nectar; I have no phase, and I have come to retire from the altar as I wish. This is a couplet written by Xu Zuwu on Ganlu Jietai Temple in Kaiyuan Temple, Quanzhou.

"Know yourself and know yourself, and fight a hundred battles" means: know what you are doing, and don't pray for others' approval as the driving force. Different people experience different lives, which may be a feeling to outsiders, but only they can truly appreciate the taste. Therefore, we should take ourselves as the starting point in life, don't listen to other people's suggestions, and don't be harsh on ourselves at the same time, which will only be counterproductive.
