Hi everyone Which door should I consider the main door: 99% of the time I use the back door to enter my home. I would drive my car into my carport and into the back entrance. My back door has similar design as the front door and both are white in color. The front door faces South where my back door faces North and may I add it faces a T-Intersection.Although I had placed a Bagua to reflect the negative Chi. Thanks in advance H.L.
