hi, on my luck pillar analysis/summary, as weak water (east), i should stay in a house facing direction for metal to further improve my luck...and avoid nw & ne as house facing direction as it will further reduce my luck. but nw, ne west and sw are the 4 good directions for metal. also, if i use house facing direction for metal, does it mean i should use all 4 good directions (west)for metal instead? thanks
