来 / 去
lái / qù
Direction complements
来 and 去 tack onto a verb to say whether the movement is towards the speaker or away.
Verb (+ Direction) + 来 / 去
How it works
我们走过去吧 — let's walk over (away from here). 走过来 would be walking over towards me.
The middle slot takes a direction: 上, 下, 进, 出, 回, 过, 起. So 进来 (come in), 出去 (go out), 回来 (come back).
With a place, it goes before 来/去: 他跑回家来了.
