Qi should always collect in front of the door, and then gently float into the property. If your Qi is being dragged away from the door, then nothing is flowing in and everything is flowing out. How does Qi get dragged away from the door, and from the building? By Pulling Nose Water.
The name Pulling Nose Water is derived from the Qi being pulled away from the Main Door, much like a cow is led away by the nose. Whenever there is a long, narrow pathway or corridor in front of a door, the door is regarded as having a Pulling Nose Water problem.
