Ancient Chinese philosopher Confucius had some interesting thoughts about what it means to be a gentleman. In his writings, he used the term “Jun-Zi” to describe that concept.
“Jun-Zi” is one who cultivates himself morally, shows loyalty where due, honors his relationships with family, and attempts to cultivate humanity and benevolence. He acts more than speaks, disciplines himself, and is obedient and knowledgeable.
Finally, I leave you with a quote:
“When I walk along with two others, they may serve me as my teachers. I will select their good qualities and follow them, their bad qualities and avoid them.”
– Confucius
