Dear Cecil and Glyn, Thank you so much for your prompt response. But still I don't seem to get the full picture yet - sorry for being slow in apprehending it! To ensure that I understand your explanations fully, could you kindly clarify for me the following: (1) A house?s plan gets divided into eight triangular sectors by super-imposing the Loupan template on it, right? (After the exact measurement of the house and its centre have been ascertained) (Please see sketch 1). Meaning that, the centre sector is an imaginary one? Say, if I have a room right in the centre of my house, this room would obviously sit on all eight sectors of the house. So the flying stars of the centre would be applicable for this room, right? (2) What about if my bedroom sits on two triangular sectors of the Luopan template (for ex: sitting on both NW and W sectors), then for the flying star calculation purposes, which sector my bedroom is really belonged to (the West or NW sector)? I have attempted to come up with a Lo Shu square for my house after super-imposing a Luopan template on my house?s plan as attached. Could you please review sketches to see whether I have done it correctly? For the attached sketches, I must apologize for sending them to your private e-mail since I could hardly figure out how to post an attachment to my mail using the Post function of the Forum site and still struggling with it (and believe it not, I'm really new to Internet). Please open them on Word 7 for Windows 95/98. I hope you do not mind so much and really appreciate your help. Very best regards, Tam
