I want to build a few houses in the countryside. Is it okay without hiring a Feng Shui master?

If you accept your fate, then it is okay not to ask (in most cases, fate affects relative things).

The purpose of hiring a Feng Shui teacher is to try to choose good luck and get good luck, and to avoid all kinds of evils. But if you ask a numerology teacher to do this, you may not be able to do it, or you may be able to do it but you are uneasy to do what he says.

Things in life are intertwined, and sometimes it is difficult to change.
