1. I stay apartment, how do I know my unit or the whole block of apartment is facing which direction? My main door is facing south west. 2. I heard that if the height of corridor (inside the house) is higher than the main door, is hard to save money and children is naughty (won't listen to parents). Just reply by email, TQ.

Dear Eric, take the facing side where the entire building was built to (meant to) face. As for the corridor - no, so don't worry. Check your children's room, and what is the cause for loss of money. Cheers - Sherwin.
