First of all, emphasize one point. Designers will involve Feng Shui knowledge in the learning process. But it is different from traditional feng shui. What designers learn is the harmony between human environment and natural environment. Traditional geomantic omen pays more attention to things, five elements and nine palaces.
So if you care about traditional geomantic omen, I suggest you find a professional geomantic omen teacher to have a look. Be sure to look at it on the spot. You need to observe the magnetic field. Master eight characters, etc.
If all you care about is comfort. Then find a good designer to solve the problem.
