Hello, I have two questions regarding compass directions: What if the main door is not located either North or NorthEast, but exactly North by Northeast, right down the middle of the two directions? Also, what is the solution if various pa kua sectors of a dwelling include more than one room -- i.e., if a wall separating the livingroom and bedroom is running through the middle of a pa kua sector? If a sector is split by such a wall, does one consider the wall as the dividing line of the sectors -- instead of using the actual compass direction? Thank you.
