要想日子過舒服，職場生崖豬啊豬。 你笑S俺了。。。

The key point is keep the ball rolling.

Talk WITH them, to get the number:

What I said was:  You know much better than I do about the budge of this position, why down't you just tell me?

Or: Come on, Don't play game with me, tell me how mauch you pay 4 this position...

Usually they will tell.

In your case, just tell a number you  feel happy about, keep the ball rolling...

你趕過集嗎？
賣豬不中， 那咱賣啥呢？
賣人是犯法的。。。
