Probably, I should make it clearer. My house belongs to Period 7. Three to four years ago, I had a practitioner to read the feng shui of my house. According to her, my house is considered to be facing West 2/3 with living room windows facing the West (cos' most yang energy enters from here) while the main entrance is on the northwest sector of the house. If I'm not wrong, in period 8, the double "8" will be at the West, i.e. my living room. Please correct me if I'm wrong. If that is the case, what must I do to activate the good stars? How about the main entrance (northwest sector)? If it does not have good star, how should I cure it? What actually does one need to do when a house is good to "change to period 8".
