Dear Sherwin, thanks so much for your kindness and time to answer my question. However, I do not know how to see or check my house gua. Is it a skill to be learned?

Dear Roseline, start by taking the facing direction of your house. The 'sitting' is the opposite of the facing direction [eg. facing North, sitting South]. The House Gua is determined by this sitting direction. From the House Gua, you will be able to tell which sectors in your house are good to use. Do have a look at the TV program downloads section in this website - very informative. Cheers!
