"These women are familiar to me."
Translation:Những người phụ nữ này quen thuộc với tôi.
"These women are familiar to me." - I recognize these women in some way although it is not necessarily mutual. (For example if I recognize them from an old picture, or they remind me of people I know/knew, but we've never met before.)
"These women are familiar with me." - these women certainly know [of]/recognize me, regardless of whether or not I am familiar with them.
"I am familiar to these women." - These women surely know who I am, or have the feeling they know of me from somewhere, though it's not necessarily mutual.
"I am familiar with these women." - I definitely know who these women are, and they probably also know who I am, although not necessarily. I would add "...and they with me" if I wanted to be clear the familiarity was mutual. :)
So the question is: what does this sentence in Vietnamese actually mean/imply?
