In a north facing house, the good sectors being north,south,east and south-east,do the luck of these good sectors change every month and every year due to the flying star feng shui? Please provide the good sectors for south and south-east facing houses. Thank you.

Dear Godfrey, Eight Mansions and Flying Stars are two distinct application methods of the San Yuan system. At this level, applying House Gua is already more than good (permanent chart). You can also incorporate the annual Flying Stars into your assessment. South facing (North sitting) is a Kan Gua (1) house. SE facing (NW sitting) is a Qian Gua (6) house - you can look at the notes available in this site to find the good sectors. Cheers! SN
