What should we pay attention to in feng shui of courtyard walls and gates?

The door is the entrance to the house for breathing in and out of air. It should be kept bright, clean and clean. It is not suitable to pile up debris to avoid hindering the movement of air and air circulation. At the same time, the door should be prevented from being in a straight line relative to other doors, so as not to affect family harmony and cause constant quarrels. If there is a wall opposite the door or you can see the scene in the opposite room, it will disrupt the normal circulation of human air and lead to disease. The position of the door can help improve luck. Different orientations bring different benefits and luck. If you face the north, your business will be prosperous, if you face the south, it will be easy to become famous, if you face the east, your family will live harmoniously and happily, and if you face the west gate, your descendants will be blessed. The northeast represents supreme wisdom, the northwest represents the ease of outward development, the southeast is conducive to wealth and prosperity, and the southwest has peach blossoms and a beautiful woman.
