It is best to drill wells in the north, but not in the northeast and southwest (there are people on duty in these two directions, so you can use other directions if you don't understand).
After 2004, the best location of your home's geomantic omen went to the middle of the house, which was not good for your fortune. Try to do more activities in the middle of the house, such as starting more fans and raising more fish. In short, just keep this posture moving all the time!
Those others are at the door, southeast and northwest, and so on. I think it's too vague. It depends on the rise and fall to decide whether it's good or bad!
