According to geomantic omen, can the window at home be blocked by half? (made of brick)

It stands to reason that when drawing a house, the position and size of the window must be carefully considered, so it will be more appropriate. Therefore, in the future, we will arrange under this premise; I won't change until I have to. If half of the vents are blocked, the vents will naturally be reduced by half, and the information exchange with the outside world (mainly lighting and ventilation) will also be reduced by half. Be careful if this window is the main air inlet; Don't touch it if you are in the ascendant position after Feng Shui. Besides, you can move if you want.
