The first method: ask a friend for a strange and kind puppy, and use the first test method. The owner of the house will take the dog home and put it at the front door. If the dog can take the initiative to enter this home for the first time, it means that your home is qualified in Feng Shui. If you enter and run, it means that your feng shui doesn't count.
If the puppy doesn't even enter the door, it means that your feng shui is not good. It's time for someone to investigate.
The second method: put 6 black goldfish and 1 golden goldfish in front of your house, and don't feed them for a week. If 1 to 3 snakeheads die within 7 days of a week, it means that the feng shui at home is average. If you are not dead, it means that the feng shui at home is very good. If the golden goldfish or all the fish are dead, it means that the feng shui at home is clear.
