Hi! Master Lee Thanks for your earlier advice. My house was built in 1987, so it is still under Period 7, instead of period 8. Thus, the Xuan Kong Fei Xing for my bedroom (North-East Direction) are #5, #9 and #1, the year flying star is #4, instead of #9, #7 and #2. In this case, shall I hang 6 emperor's coins with red string at my bedroom's window or bed head? Or it is better to place a bronze Hulu at my bed head?Or where should I place it and can I recycle the 6 coins which I used them in my previous house? My husband sleeps under a ceiling light and his waist is right under it. That's why sometimes he feels that his waist is a bit pain. Besides, moving bed, what is the solution for this? Please advise me. Thanks for all your advice. Mrs Tan
