Is there anything to say in Feng Shui when the window cover is installed crookedly?

Window represents eyes, but the situation you described should not have much impact. This is just a problem of construction errors and has nothing to do with Feng Shui.

If you think it will have an impact , then there is a realistic situation to verify, see what direction this direction belongs to, and then cooperate with the corresponding family members to see if that person’s eyes have strabismus. I think this situation is too ridiculous, please don’t remember it. It has no impact.
