I just purchase one unit of HDB, the construction of the block is at period 7, but the house owner did a renovation last year,when i using your free flying star report i should select period 7 or 8. And this unit is at 10 floor i should the the direciton of the house from main door or the window? I friend told me that the main door(located at south) is the no 5 star and is very bad for the family, what can i do to encounter this? Thanks and best regards. Mrs Leong
