In fact, it's not Feng Shui that affects brothers, but your current psychology that affects feelings. You should sit down and have a good discussion, not talk about Feng Shui. Mentality is the key. If you want to change the future, you need to change your mentality first.
It took thousands of years to unite as one and form a lifelong brotherhood. Please cherish.
You must be a man before you can do Feng Shui. Only by doing good deeds and accumulating virtue can the blessings last forever.
May you three brothers live in harmony and have a happy family.
