My new house main door is facing North, back door is facing South. No side doors

My kua is 6. Auspicious direction is W, NE, SW, NW. I am trying to change the front door to NW.

Quite a number of years back I consultated a fengshui master for my old house, he advise me to use a pair 0.5m (H) of fengshui lion dog (Fu Dog) and place it facing my auspicious direction on my front door. Eg: My actual front door is North, I placed the the Fu Dog facing NorthWest, by doing this it will change my house direction facing. I just want to clarify if this is true or workable?

Thanks in advance.

Why don't you post your house plan and the google map of your property to see if changing door help.

As I understand it, the "main door" is the door used most to enter the home. You can change the "main door" to South by
using the back door more. To change the "main door" to any other direction would require you to constuct another entry - as in
cutting out wall space and building a frame for a door.

If you got windows facing your auspicious direction, try to always open it. Better than nothing since windows size is just half or smaller than the door size.
