Ask feng shui master, does it affect me if my neighbor heightens the iron pipe?

This should have little impact. First of all, in Feng Shui, we usually look at the height of a house by the number of floors, appearance and surrounding area. As for the surrounding area, we are very careful not to form a pattern that people are taller than me, but we don't mean that people are taller than you, but that you are taller than you in all directions in the building group, and only your home is sunken, especially the short house. If you are in a row of buildings, but the height next to it is higher, that's no problem. Unless someone heightens it, there is something feng shui pointing at you, that's another matter, otherwise the landlord doesn't have to care, the height of the house is what he likes.
