請問一下,我們有面交,如果直翻成we have face to face, 這樣ok嗎?

不能"中文字直接字轉字的直譯"！

最直接也只能寫/講成
we met face to face

面交=見到面(交談)本身已經是意釋而非直譯

假如你仍要指明或強調(有)have視為必要的動詞的話，便要加很多字或改變寫法：

we have a face to face meeting.
we have discussed the matter face to face.
we have met face to face.

We have a face to face opposite encounter experience.

We come together with face to face.

不要受中文影響 面交就是親自交易 所以翻成 We can have a deal in person. 就可以

charge in person.
we have "charge in person" choice.

你的問題是我們面交過、我們有面交還是我們在面交？

We had a face-to-face
我們面交過

we have talked face-to-face
