1. Compass.

2. Watching the sunrise and sunset.

3. At night, look at the direction of the handle of the Big Dipper

4. Look at the crown of the tree, the dense south, the moss on the trunk of the tree, the color of the darker north.

The following other ways to refer to:

1. Observe the sun - the sun rises in the east and sets in the west, observing the sunrise and sunset can generally be seen in a general direction (for example, at 6:00 a.m., the sun rises in the east, and the shadows of all the objects are inverted to the west; at 12:00 p.m., the sun is located in the south, and the shadows will be By 12 noon, when the sun is in the south, the shadows point to the north; by 6 p.m., when the sun is in the west, the shadows point to the east. Thus, directions can be approximated by the sun and the shadows of objects.)

2. Branches and leaves of a tree - the south side is lush, the north side is sparse;

3. Standing pole - set up a pole vertically on the ground, the shadow points to the northwest in the morning, the shadow points to the northeast in the afternoon, the shadow is the shortest at noon, when the shadow points to the north. The shortest shadow is at noon, when the shadow points to the north;

4. Observe the North Star - at night, under the dark moon and bright starry night sky, we will always find the Big Dipper, which is shaped like a spoon, and at the end of the spoon, there is a bright star at seven times the distance, and that is the North Star, which is directly under the north, and clockwise, that is, the east, the south, and the west;

5. Observe the ants' burrows - most of them are facing south;

6. Observe the ants' burrows - most of them are facing south;

7. Observe the rocks - the moss-covered side is the north side, and the dry bare side is the south side;

8. Observe the rocks - the moss-covered side is the north side, and the dry bare side is the south side. 8. Watch - divide the time you are in by 2 and point the resulting quotient at the sun, and the direction of 12 on the dial will be north.
