Origin 900 to 1100 CE
The luopan is the compass of the feng shui practitioner, the specialised instrument by which a site is oriented and read. At its centre sits a magnetic needle in a small well, the heaven pool, and around it are arranged a series of concentric rings, sometimes many dozens of them, inscribed with the directions, the trigrams, the Heavenly Stems and Earthly Branches, the five agents, the twenty-four directional mountains, the lunar mansions and other systems of correspondence. By aligning the instrument and reading the rings against the features of a landscape or building, the geomancer assesses the flow of qi through a place and determines favourable orientations for a house, a grave or a doorway. It is at once a magnetic compass, an early and sophisticated use of the lodestone, and a cosmological diagram made portable, encoding the whole apparatus of Chinese correlative thought on a single dial.

The Compass That Reads a Landscape
The luopan is the compass of the feng shui practitioner, the specialised instrument by which a site is oriented and read according to the principles of Chinese geomancy.
Rings around a needle
At the centre of the luopan sits a magnetic needle, and around it are arranged concentric rings inscribed with the directions, the trigrams, the celestial stems and earthly branches, the constellations and the other categories of Chinese cosmology, so that once the needle is aligned the practitioner can read from the rings the qualities assigned to each direction at that spot. The instrument thus condenses a whole cosmological system into a device that can be turned upon a particular place, and reading it is a specialised skill requiring long training.
Siting the living and the dead
Feng shui, the art of siting buildings, rooms and graves so as to accord with the currents of the landscape, uses the luopan to determine the auspicious orientation of a house, a door or a tomb, and the placing of a grave in particular is held to affect the fortunes of the descendants, which made the geomancer a figure of real consequence. The instrument is the practitioner essential tool, the means by which the invisible qualities of a site are made legible. It belongs to the broad world of Chinese religion and cosmology, drawing on the same categories used in divination and the calendar, and it remains in use wherever feng shui is practised, from the siting of graves to the arrangement of modern buildings.
A Precision Instrument, Not a Toy Compass
A luopan is built around a central magnetic needle surrounded by dozens of concentric printed rings, each ring encoding a different system, the Later Heaven Bagua, the twenty four mountain directions, the heavenly stems and earthly branches, and star correspondences among them, which makes it closer in complexity to a specialized surveying instrument than to a simple compass.
A specific, shrinking craft
Producing one requires three combined skills, precision woodworking for the base, fine calligraphy or printing for the rings, which must align exactly with the needle, and compass calibration itself, a combination historically concentrated in a small number of specialist workshops, Xiuning county in Anhui among the most documented centers of the trade, a craft now under pressure from mass produced simplified compasses and phone applications that replicate the calculations without the physical instrument.
Who uses it, and how it is kept
A luopan is not restricted from ownership, but correctly reading it, rather than simply owning one, is a trained feng shui practitioner's skill, comparable to owning a sextant without knowing celestial navigation. A working luopan is kept away from other magnetic objects that could throw off its needle, and a serious practitioner periodically checks its calibration, treating it as a professional tool to be maintained rather than a decorative object to be displayed.
Cross-Tradition Connections
Belongs to Tradition
The luopan carries the compass needle inside rings of trigrams, stems and branches, so it is a calculating instrument and not only a direction finder.
