吾當避此人出一頭地的意思

"吾當避此人出一頭地"這句話的意思是，我應該避免與這個人競爭，讓他能夠在某些方面超越我，或者說，我應該讓這個人有機會展現自己的能力，而不與之爭搶。

在中文裡，"避" means "避免"，"此人" means "這個人"，"出" means "超越"，"一頭地" is an idiomatic expression that means "to stand out" or "to be superior".

So, the literal translation of "吾當避此人出一頭地" would be "I should avoid competing with this person so that they can stand out".

This phrase implies that you are willing to step aside and give someone else the opportunity to excel, perhaps because you believe that they have the potential to achieve more in a particular area, or because you want to maintain a harmonious relationship with them.
