In what direction does SiNa's spoon handle point?

South. Sina is generally the ancient name of compass, and its main component is a spoon installed on the shaft. Under the action of natural geomagnetic field, the spoon can rotate freely and keep in the tangential direction of magnetic meridian, and the south pole of the magnetic needle points to the geographical south pole (magnetic north pole), so we can use this property to identify the direction. SiNa spoon handle points to the south, because the magnet will automatically find the midpoint of the magnetic field under the action of the earth's magnetic field, which is the geographical south pole, so SiNa spoon handle will point to the south. In ancient China, Sina was first used for ritual, etiquette, military affairs, divination, and orientation determination when watching Feng Shui.
