Dear Master, Yes, it is called Flying Star chart, as referred my favourable sector and direction is worst to fit for my bed, currently the bed is locate at SW sector and facing West which I refer to my Flying Star chart is the worst location, any advice from Master. Currently the Flying Star chart is base on current built up area excluding my plan Extension on side 10ft land, if I extend it later, will this Flying Star chart proportion will change accordingly, if this is the case, then all my current Sectors will become larger compare before Extension, am I right?
