Hello, Based on the Kua formula, I have recently learned that I belong to the east group and my partner is a west group person. My Kua number = 9 His Kua number = 7 We would like to buy a house in the near future. The problem we don't know which direction chart to use...should we base the location of our kitchen, bedroom, bathroom, and main door on an east or west group person's lucky direction? Do we buy a house suited for an east or west group person?
