Dear Master Cecil/Robert, Under the Eight House, it takes into consideration of a person's year of birth to determine 4 best and 4 bad direction. On the other hand, a person's element is determined by its ba zhi and a house element is determined by its facing direction i.e. North House is water element, Southeast is wood element. For a west group person, its good direction is W, NW, NE and SW. What if he is also a weak fire which require wood to make him more strong. Can he live in a SE house with its main door facing NE and bed direction facing SW. Does it work like that? Your advice is appreciated. Thanks. Joan
