There is no need to pay attention to the ground form above the third floor of the building, which has no influence on you. And you are only the owner of a unit, not the owner of the whole building, so you don't have to look at such a big situation. It is better to see if the land traffic in the whole area is booming. So it is more practical for you to pay more attention to the sitting direction of your house.
I hope it helps you.
