Is it possible to seal the front door of a Feng Shui store against the back door?

The front door of the store faces the back door. The back door can be blocked. The door is the air outlet. If the front and back doors are facing each other, it will be regarded as the coming and going of wealth in Feng Shui. If there is no wind, there will be no prosperity. Wealth also means that there is money coming but it is difficult to accumulate it. If you need to leave a back door for transporting items and making it easier to get in and out, you can follow the rules of the door light star. The front door is wide and tall, and the back door is shorter and narrower than the front door. It is better to set a threshold at the back door and open the back door less often, so it will not be a problem.
