Facing the sun in the morning, the front is east and the back is west. What's the next sentence?
The sun rises in the east and sets in the west, which is the most basic way to tell the direction. You can also use the stick shadow method to measure. When the sunlight is enough to form a shadow, erect a straight stick (more than 1 m) on the flat ground and place a stone (or other mark) on the top of the shadow of the stick. The shadow of the stick will move with the sun.
After 30-60 minutes, put another stone on the shadow top of the stick again. Then draw a straight line between the two stones, and draw a straight line perpendicular to it in the middle of this straight line. Then step on the first mark with your left foot and the second mark with your right foot. At this time, the front of the standing person is due north, the back is due south, the right hand is east and the left hand is west.
Extended data:
Use the stars to tell the direction:
Polaris is located in the sky due north. When observed, its height from the ground is approximately equivalent to the local latitude. When looking for it, it is usually determined according to the Big Dipper (Ursa Major) or the W Star (Hou Xian constellation).
The Big Dipper is seven bright stars, shaped like a spoon. It extends a straight line from the spoon head to the spoon mouth, which is about five times the distance between the two stars. There is also a slightly darker star, the Polaris.
When the earth rotates and can't see the Big Dipper, W star can be used to find it. W star is composed of five bright stars, shaped like a "W" letter, and extends to the direction of the W-shaped gap by about twice the width of the gap, which is the Polaris.
