Is there anyone who knows indoor feng shui to help me see how my three fish tanks are arranged?

I can tell you for sure that renting a house also depends on Feng Shui.

Since moving into this house, both husband and wife have become very unhappy emotionally and at work because they have tried to rent a house. Besides quarreling every day, one of us finally lost his job. Later, when we moved out, our neighbors came and said that the room was not feng shui. As far as we know, this room belongs to the landlord's younger brother, who has lived with his wife for some time and has divorced. Later my brother gave the house to the landlord. Since the landlord moved in, he was addicted to gambling and lost 600 thousand, so his wife divorced him. He also felt that the house was not feng shui, so he moved out and rented it out. Now, I also look at the knowledge of Feng Shui from time to time. After calculation, the owner of this room has a door facing the kitchen, and he can also look at the kitchen. On the other side of the wall next to the bed is someone else's kitchen. Every morning, I feel that I am sleeping next to someone else's kitchen, listening to others cutting vegetables and cooking. That kind of feeling makes people very dry, feels like the body is on fire, and is often in a bad mood. I think maybe because of this, we often quarreled, our interpersonal relationship became tense, and finally we lost our jobs.

So, I suggest you find a house and have a look at Feng Shui yourself.
