Feng Shui Compass
风水罗盘 · True North & Magnetic North
The Evolution of Feng Shui Architecture
In ancient times, houses were built from organic materials like timber, brick, clay, and tile. The traditional Feng Shui compass—the Luopan—was a precision instrument because its magnetic needle responded purely to the Earth's natural magnetic field.
古时房屋以木、砖、土、瓦等天然材料建造，罗盘磁针纯粹顺应地磁，故能精准定向。
The Modern Urban Challenge
Today's buildings are packed with ferromagnetic materials: steel columns, rebar mesh, metal frames, lifts, parked vehicles, and buried cables. All of these distort a magnetic needle. Even within the same property, standing in different rooms while facing the identical direction can cause Luopan readings to deviate by up to 20 degrees. Some practitioners attempt to solve this by measuring from the street or a nearby park. However, modern cities are surrounded by steel-reinforced high-rises, metal railings, lamp posts, and underground transit lines. In these environments, the needle still wanders, making it incredibly challenging to lock down a property's definitive facing orientation.
现代建筑充满钢柱、钢筋、金属框架、电梯、车辆与地下电缆，均会扭曲磁针；同一屋宅不同房间读数可偏差达20度。即便在街道或公园测量，四周高楼、栏杆、灯柱与地铁线仍使磁针游移，难以锁定准确坐向。
The Problem with Magnetic Drift
Furthermore, the Earth's magnetic poles drift constantly year by year. If a property's facing reading changes based on the random magnetic fluctuations of the day it is measured, its natal chart would shift drastically every few years. Yet, a property's natal chart is meant to be permanent. At the moment of "birth"—when construction is completed and the occupants move in—the cosmic energy of that exact instance is sealed into the structure.
地球磁极逐年漂移，若坐向随当日磁场波动而变，宅命盘每隔数年便会偏移。然宅命盘应以屋宅竣工、入宅之时为"诞生"定格，封存当时宇宙能量。
The Solar Alignment Alternative
One school of thought argues that Xuan Kong Flying Star formulas are fundamentally based on solar alignment and planetary movements, which are entirely independent of the Earth's fluctuating magnetic field. Therefore, many practitioners advocate using True Geographical North—which remains fixed forever—as the primary reference instead of Magnetic North.
有学派认为玄空飞星以太阳方位与行星运行为本，不受地磁波动影响，故主张以永恒固定的真地理北取代磁北为基准。
Definite Precision for Both Methodologies
Our feng shui compass platform bridges both philosophies by offering both True North and Magnetic North readings. After extracting the True North data from high-resolution satellite maps, the app references the exact geomagnetic data system used by surveyors and aviation to calculate the clean, uncorrupted Magnetic North reading for that precise geographic coordinate.
本平台融合两派，同步提供真北与磁北。先从高清卫星图提取真北，再参照测量与航空所用的地磁数据系统，计算该坐标下无干扰的精确磁北读数。
Capturing the Moment of Birth
Best of all, our system allows you to calculate the precise magnetic facing for the exact year the property was completed. By bypassing physical needle interference and accounting for historical magnetic drift, our platform eliminates the critical mistake of deriving the wrong natal chart, ensuring absolute repeatability and accuracy.
更可依据屋宅落成当年计算精确磁北坐向，规避实体磁针干扰与历史磁偏角漂移，避免错推宅命盘，确保结果可重复、准确。
