In primary school, it is represented by the combination of direction, position and distance. Example: 45 degrees east of north, 2 kilometers away. It is equivalent to the azimuth and distance from the original point to the coordinate point in junior high school analytic geometry.

North, south, left, west, right and east form a cross, which is the same as the orientation on the map. Other directions are indicated by north deviation or south deviation, and generally there is no east deviation or west deviation.
