Thank you for your quick response, and sorry that I confuse you. My house has mountain star #8 at the facing direction (instead of sitting direction), and water star #8 at the sitting direction (instead of facing direction). According to flying star, this house is "reverse". BR #5 is bedroom number 5 in the N (or NW?) sector of the house, same with BR number 2 in the E (or SE?) sector of the house, I don't know how to determine which sector these BRs belong to. Again, thank you for your help.
