Dear Master Lee, As per my study with the help of your Bazi premium report.I have understood that the main door has to face West or North west.As aweak water person my main door is facing North that is disaster so I am using my kitchen door which is also my back door as my main door but my main convern is ! it is facing the laundry room and toilet.Please advice me if that is ok or I have to use a cure such as concave mirror.IF yes, what size concave mirror would be appropriate? Sincerely, Amit
