Can your own chimney face the gate? Can your own house face the south gate and the chimney face the gate?

The door is facing the chimney, and the impact on the residents depends on the specific distance. If it is more than 500 meters, it belongs to a long distance, and the impact on your home's geomantic omen and environment will be very small and basically negligible.

If the distance is 200 to 500 meters, it is best to hang a flat mirror at the door.

If the distance is less than 200 meters, if there is smoke, it will not only affect the residents, but also block them. If you don't cook often, the airflow has no effect, but it will slightly affect the light source. In geomantic omen, it also belongs to the sky, which will affect people's luck and fortune. For example, if a needle sticks into the door, it will form a right octagonal convex mirror that needs to be hung at the door to ward off evil spirits, and then you have to put a five-emperor money at the door to ward off evil spirits for long-term luck. It's best to put a fish tank at home to raise some fish, or put a god of wealth to make people lucky.
