I never open this window because of the neighbor's wall disgusting view :( 
so  fresh air didn't enter and temp get hot especially in summer
Plywood panels will arranged to hide the view and let the air in
Plywood panels will be installed with 45 degree angle so 
i can't see anything outside and no one see me from outside too

Finally i can open the window and the air can enter :)
It works perfectly but the panels looks too long and start bending
My wife came with idea to cut in half so it will be strong and don't bend 
and so i did :)
