{ "heading": "Luopan: The Feng Shui Master's Compass", "body": "## What is a Luopan?\n\n\nThe **Luopan** (Lo Pan) is a Chinese magnetic compass, also known as a Geomantic Compass. Unlike a standard hiking compass that only points North, a Luopan is a complex instrument containing up to 40 concentric rings of data.\n\n\nThe name *Luo* means \"everything\" or \"net,\" and *Pan* means \"plate\" or \"utensil.\" Thus, it is a utensil that contains the net of all knowledge—directions, astronomy, time cycles, and the Five Elements.\n\n\n## Structure of the Luopan\n\n\nA typical Luopan consists of:\n\n\n- **Heaven Pool (Tian Chi):** The central magnetic compass. It points to the magnetic South (in traditional Chinese convention) but is used to find magnetic North.\n\n- **Earth Plate (Di Pan):** The square base representing the Earth.\n\n- **Heaven Dial (Tian Pan):** The rotatable inner disc containing the rings of formulas.\n\n- **Cross Threads:** Two red nylon threads crossing at 90 degrees to align the compass with the building's facade.\n\n\n## How to Measure Facing Direction\n\n\n- **Stand Correctly:** Stand parallel to the front door or the facing side of the building, looking outward.\n\n- **Hold Steady:** Hold the Luopan level at waist height.\n\n- **Align the Needle:** Rotate the dial until the needle in the Heaven Pool aligns with the North-South markings.\n\n- **Read the Cross Thread:** Look at where the vertical red thread crosses the degree ring. This degree (e.g., 185° South) is your home's facing direction." }
