What does the ancient Feng Shui compass look like? It is best to have a clear picture and how to use it.

1. Tianchi: also called the seabed, which is also the compass. The Tianchi of the compass is composed of a thimble, a magnetic needle, a seabed line, a cylindrical outer box, and a glass cover, which is fixed in the center of the inner disk. There is a pointed thimble in the center of the bottom of the round box. There is a concave hole in the center of the bottom of the magnetic needle. The magnetic needle is placed on the thimble. The arrow-headed end of a compass points to south, and the other end points to north. There is a red line drawn on the bottom of Tianchi (the seabed), called the seabed line. There are two red dots on both sides of the northern end. When using it, the north end of the magnetic needle should coincide with the seabed line. A modern compass has cross lines drawn on the sea floor. When using it, the north end of the magnetic needle should point to the north end of the cross line on the sea floor, and the magnetic needle should coincide with the north-south line on the sea floor. 2. Inner disk: It is the rotating disk immediately outside the compass. There are many concentric circles printed on the inner disk, and each circle is called a layer. Each layer is divided into different equal parts, some layers have more grids, some have fewer grids, the smallest layer is only divided into eight grids, and the layer with the most grids has 384 grids. Different characters are printed on each grid. There are many types of compasses, some with many layers and some with few. The most has fifty-two layers and the least has only five. The various contents of the compass are engraved on different circles (layers) of the inner disk, which are the main components of the compass. Each school of Feng Shui has included its main content on the compass, making the Chinese compass a large encyclopedia of Chinese magic. 3. Outer Disk The outer disk is square and is the tray of the inner disk. There is a small hole at the midpoint of each of the four sides, and the red lines are inserted into it to form the ten channels of Tianxin, which are used to read the contents on the inner disk. The ten paths of Tianxin are required to be perpendicular to each other. The outer disk of the new compass you just bought must be calibrated before use. The compass is a basic tool for measuring the magnetic azimuth angle of the earth's surface and is widely used in various fields such as military, navigation, surveying and mapping, forestry, exploration, and construction. 4. There are many materials for making Feng Shui compasses, including bakelite, plastic, MDF, and red sandalwood. The best and most practical material is of course diamond plate, and the price is much lower than red sandalwood. 5. There are many factions of Feng Shui compasses, including the commonly seen Sanhe, Sanyuan, Xuankong Feixing, Guolu Yinyang Golden Suoyu Pass, Xuankong method, Eight Houses method, Qiankun National Treasure, and Longmen Daba Some compasses, such as Bureau Water Method, combine the Three Methods, Three Yuan Method, Xuan Kong Method, Eight Houses Method, Qiankun National Treasure, and Longmen Great Eight Bureau Water Method into one. The compass is actually a tool used to measure the ground position using the compass positioning principle. The compass is used in Feng Shui to remove sand, collect water and determine the direction of the building.
