How it's used

This idiom is frequently used as a polite, self-deprecating remark when offering an opinion or performing a skill in the presence of someone more experienced. While it literally refers to displaying axe skills in front of the master carpenter Lu Ban, it functions as a way to show humility and respect for the other person's expertise. It is often used to preemptively soften the impact of one's own contribution.

Examples

I am showing off in front of an expert, I am really sorry.
Are you not afraid of being laughed at for showing off in front of the master?
