無私 in Chinese / Japanese...

無私 would be literally translated as “none self” in Chinese, Korean, and Japanese.

It is used to express “selflessness” or “unselfish.”

無私 is a popular term for the idea of being selfless or unselfish in modern China and Japan.
This term is not as commonly used in Korea but still has good meaning.

大公無私 is a Chinese proverb that comes from an old story from some time before 476 BC. About a man named Qi Huangyang, who was commissioned by the king to select the best person for a certain job in the Imperial Court.

Qi Huangyang selected his enemy for the job. The king was very confused by the selection, but Qi Huangyang explained that he was asked to find the best person for the job, not necessarily someone that he liked or had a friendship with.

Later, Confucius commented on how unselfish and impartial Qi Huangyang was by saying, “Da Gong Wu Si” which, if you look it up in a Chinese dictionary, is generally translated as “Unselfish” or “Just and Fair.”

If you translate each character, you'd have something like

“Big/Deep Justice Without Self.”

Direct translations like this leave out a lot of what the Chinese characters really say. Use your imagination, and suddenly you realize that “without self” means “without thinking about yourself in the decision” - together, these two words mean “unselfish.” The first two characters serve to drive the point home that we are talking about a concept that is similar to “blind justice.”

One of my Chinese-English dictionaries translates this simply as “just and fair.” So that is the short and simple version.

Note: This can be pronounced in Korean, but it's not a commonly used term.
