Hihi, thanks for your quick reply.. Meaning I say the phrase you mentioned, knock on any floor or any wall not in the north and south directions, and do simple prayers at 4 corners of the living/dining room this Wednesday to symbolize the start of renovations. Then actual renovations start in 1 - 2 wks time. (I'm not cantonese so I can do away with knocking at all 4 corners and just knock at one spot). Right? To find out which wall is not the north and south direction, I look at the floor plan and just find a east or west wall? Since we cannt complete the renovations before the move-in to be in time for the wedding, I believe the best we can do in this situation will be: Before the wedding, the master bedroom renovations will be completed and we will pause renovations for the whole house, clean up the place, do the move-in procedures, stove is "installed", put sofa and dining table in place, sleep-overnight, and a few days later, do the an chuang procedures. Around 1 wk later after the wedding, sofa and dining table to move into 3rd bedroom temporarily and renovations will continue again for the living/dining room and 2nd bedroom. (no hacking, flooring and painting completed, mainly doing the interior deco stuff such as fixing up tv console, feature wall, put back sofa and dining table after completion.) Any other major contradiction in the flow above, as compared to the best scenario of moving-in and an chuang after renovation completion? Thanks much for your advise.
