Scene turns weird in game view

I've import a 3D scene from blender to unity via fbx format. And an error occurred, most model were in the wrong position. Even though I set it manually, it still show a wrong setting in 'Game View'. Is there anyone got clue?

I think this has something to do with blender, when you export the models as a FBX you need to have something enabled and that will do something with the rotation. here is a link:

the second thing that i can think of is in unity at the top of the scene view you have two buttons called "Pivot" and "Global". Click on the Global one and it should say Local check and see if they make a difference :)
