Following the practise of "Feng Shui", what is the best place to position a bed in a bedroom?

Answer 1

First check the room for good walls such as one that does not have a bathroom on the other side. Check that you can see the door into the bedroom from your bed. If you still have choices use a compass to check the direction of your head. Your birthday determines your 4 good directions and you should try to point your head in that direction. Try not to float your bed in the center of the room so you have a solid wall behind you. Also don't put it up against a wall on one side because the chi needs to circulate around you.
You can check your 4 good directions here .

Answer 2

easiest get a fengshui auditor to do it for you.

difficult:
get your kua, decide your good location and direction and put your bed there.
also get a good direction for your door, so that the people inside can be healthy, this is 2 conecpts in one at least
then you can also calculate and decide which area is less yang, so that you can sleep well.

meaning the latter part, you got to study fengshui to learn it. it is not that easy even to explain them all here.

fengshui is about formulas, configurations and calculations, not colors, furniture arrangements! study them and you will go far.
