The good or bad Feng Shui of a house is largely determined by the orientation and positioning of the main door. As the main entry and exit point for the entire family, it serves as the primary passage connecting the internal and external spaces—akin to the throat in the human body.

It acts as the first barrier for the family to embrace good luck and ward off misfortune. The Feng Shui of the main door directly impacts the family's career, education, financial prospects, and more. Therefore, when decorating and designing the main door, it's beneficial to consider Feng Shui principles to transform negative influences into positive ones, aiming to attract good fortune and avoid harm.

Here are three basic Feng Shui principles:

1.Seeing Red When Opening the Door: This means that upon opening the main door, one should immediately see red screens, totems, or decorations. In Chinese culture, red symbolizes joy and celebration, giving people a sense of happiness and warmth.

2.Seeing Green When Opening the Door: This suggests that upon entering the main door, one should see red flowers and green leaves. Scientifically proven, the color green provides the widest visual field and instantly fills the entire space with vitality. It gives people a feeling of freshness and liveliness, providing an instant mood boost and stress relief.

3.Seeing "Fu" (福) When Opening the Door: This implies that upon entering the home, one should see scenes that evoke happiness and joy—such as a beautiful natural landscape painting or a crafted artwork. This helps adjust the tense and fatigued mental state.

Here are five taboos to avoid:

1.Avoid Seeing the Stove First: From a Feng Shui perspective, seeing the stove upon opening the door may lead to financial loss for the homeowner.

2.Avoid Seeing the Toilet First: Seeing the toilet upon opening the door is discouraged because it is a place for waste and impurities. Having impurities welcome the homeowner is believed to be detrimental to family health.

3.Avoid Seeing a Mirror First: Mirrors, with their reflective properties, are generally used to reflect energy outward. However, if a mirror is positioned to reflect towards the entrance, it may deflect the homeowner's energy, leading to a decrease in personal energy.

4.Avoid Beams Over the Door: Having a beam directly over the entrance may create a feeling of oppression, hindering personal development. It may make it difficult for the homeowner to stand out, leading to a subdued mood.

5.Avoid Creating an Archway Resembling a Tombstone: Designing the door in the shape of an arch resembling a tombstone or resembling a cemetery may bring misfortune to the family.

The design of a home's main door is crucial, influencing the family's luck. Chinese expressions such as "寒门" (poor family) and "贵门" (wealthy family) underscore the importance of the main door's Feng Shui for a household's prosperity.
