Can someone else's back door stand in the middle of mine? Will the other party not let a wall be erected?

Hello, I'm glad to answer your question. Back door to back door, never heard of anything. First, only the front door and the back door cannot be opposed. If the front and rear doors of the house are opposite, it will lead to death. Generally speaking, the walkways of gas gathering rooms are curved. The qi gathered in this pattern is warm and gentle, which is good for nourishing the heart and qi and increasing prosperity. If the house has a back door, it should be staggered from the front door, so that the air can enter and exit in an S shape and gather indoors. If it moves in a straight line, the gas will be missed by walking in a straight line. Although the convective wind caused by the front and rear doors is cool, it is also very dangerous and easy to damage people's health. Second, if the back door is not commonly used, it is best to seal it.
