Let's have good Feng Shui Bedroom from the entrance
Do not put anything blocking door area.
-- You should see an open space as much as possible after you open the doors. Avoid putting bookcase, bed, frame or even wall at the door area. It's not a good Feng Shui bedroom.
What if you cannot have an open space
-- You can solve the problem by hanging mirror on the bookcase, bed frame or wall that block your door area to allow energies to flow through your bedroom. This approach can help you to keep good Feng Shui Bedroom in your house, especially in the front area.
