I saw this phrase recently in a post online. The whole sentence is
人生得一知己足矣. I think
人生得一知己 means "getting a BFF(?) in one's life". (The only meaning of the word
知己 that I know of is BFF, but please correct me if I am wrong!) What does
足矣 mean? Is it a phrase or is it two separate words that just happened to be together in this example?
By the way, is this a phrase used in classical Chinese? The sentence structure looks different from modern Chinese.
