Which of the six main rooms has the most feng shui?

That room has geomantic omen to see who lives. If it is reasonable to say that the middle two rooms are good, it is warm in winter and cool in summer, and there is no specific good geomantic omen. When feng shui is good and bad, it is good feng shui if the environment does not affect the house in general. I like that one and live in that one. The above are personal opinions for reference and study.

I wish you all the best.

Good luck.
