Hi

I read that the altar should be at the back half of the home, I have a spare room but is color pink, is this ok?

Also, you should face your kua number direction, I have a 9 kua number but my wife is a 5 kua number. Which should we use?

Thank you

Just place your altar facing the main door, that's it, regardless of any of your gua number my friend! Altar is a holy place to worship Buddha and Buddha is not being affected by any gua numbers, got it ?
