See if there are any big buildings or obstacles in front of you, and what Feng Shui calls "backstab" has happened. A neighbor's satellite antenna, a street telephone pole, a church steeple, or a long road facing your door-all these can form the so-called "stab in the back." If something that can be a "stab in the back" is pointing at your front door, then in order to resolve this harmful influence, you should hang a gossip mirror at the front door with the mirror mouth facing outwards.
