1. Recite the direction children's song: "Get up in the morning and face the sun. The front is east, the back is west, the left is north, and the right is south. " The sun rises in the east and sets in the west. In the morning and evening, we can distinguish the southeast and northwest directions according to the direction of the sun.
2. use a compass to identify the direction. Compass, called Sina in ancient times, is mainly composed of magnetic needles installed on the shaft. Under the action of natural geomagnetic field, the magnetic needle can rotate freely and keep in the tangential direction of magnetic meridian. The north pole of the magnetic needle points to the geographical south pole, and this property can be used to identify the direction.
3. Identify the direction according to the growth of trees. If you absorb enough sunlight, the branches and leaves will naturally grow thick. From this, it can be seen that the south is on one side with dense leaves, and the north is on the other side, so that the direction of east, west, north and south can be judged.
4. Identify the direction by the moss of stones or roots. Moss likes to grow in wet places, find sunny places, and then distinguish sunny south.
5. Confirm the direction with Polaris at night. If there are beautiful stars in the night sky, you can find Polaris through the three northern constellations, and the orientation of Polaris is in the north, so as to distinguish the southeast and northwest directions.

Geographical direction: the east is the same direction of the earth's rotation, the west is the opposite direction of the earth's rotation, and the east-west direction is also the latitude circle direction. There is no end to the east-west direction on the earth. If we start from somewhere along the latitude direction and go east, we will never reach the end of the east, just walk around the latitude circle.
On the contrary, the north-south direction on the earth is polar. When we start from the equator and go north or south, we will finally go to the North Pole and South Pole, and when we cross the North Pole or South Pole, the direction will change. In the North Pole and South Pole, there is no east or west direction. There is only one direction in the North Pole-south; Antarctica has only one direction-the north.
If you get a map without orientation marks, first look at whether the map is marked with longitude and latitude lines, with latitude lines indicating the east-west direction and longitude lines indicating the north-south direction. If the edge of the map is marked with orientation marks, then the orientation needle arrow refers to the north. If there is no mark on the map, it means that it is north above, south below, west on the left and east on the right.
