Dear Cecil In my neighbourhood, the Govt has started roof repairs to HDB flats and soon an entire block's external facade will be repainted. Walls of common areas eg corridors, stairwells, lobby, etc will also be given a fresh coat of paint. Will these measures be sufficientto changemy flat from Period 7 to Period 8 especially if I do not renovate my unitor repaint myunit's ceiling in one session? My flat facing is SW2. If changed to Period 8, my water star #8 flies to my master bedroom's toilet where it would be wasted. I actually prefer to remain at Period 7 because my #8 water star is in the living room. What is chi of Period 8?Some website advised if you cannot change the period of your flat you can welcome the chi of period 8 by opening a window in NW. Can the chi of period 8 alter the natal chart's flying stars? From 4 Feb 2008, I will have all the earth flying stars in my South corner ie #2, #5 and #8 (WS).Will #8 overrule #2 and #5 so that no cures are necessary? Should I put water to weaken Fire of South so there is less earth produced? If I put metal, will Fire melt the metal rendering it useless for curing earth? Is there a way to cure #2 and #5 without hurting #8? Awaiting your wise clarifications.
