Hello, i have a problem with my main entrance door directly facing the lamp post located oppsite the road. After i get all book research, they have recomend build a wall(4 ft W x 10 ft H) 4ft away from the main door. It automaticly blok the bad qi/poison arrow from the opposite. The wall are inside the car porch, means new entrance will side way. I dont wan relocate the main entrace because it cost me alot. By the way, i also seldom seen front house have a wall block the Main Door. Anywhere, any sifu can provide a picture/advise is it posisble i do it before i regret. Thanks
