Southeast, Northwest formula: up, north, down, south, left, west, right, east.
The sun rises in the east and sets in the west (east and west know, or left west right east, the hand that can pick up the pen and write is the right hand, and vice versa) The directions commonly used by people are mainly up, down, east, west, south, and north. On Earth, the direction pointing to the center of the earth is down, the direction against the center of the earth is up, and the direction of both up and down is perpendicular.
What we're going to talk about now is the direction on the ground plane.
At ground level, East (due east), West (due west), South (due south), and north (due north) are the four most basic directions. The determination of the direction on the earth is related to the rotation of the earth. Looking from north to south, people call the direction of the earth's rotation from west to east.
On the earth, the direction of rotation of the earth is east, the direction of rotation of the reverse earth is west, and the horizon direction perpendicular to the east-west direction is called the north-south direction.
The horizon direction is determined based on the meridians and parallels. Specifically, all parallels indicate due east and west. The direction of the Earth's rotation along the latitude line is due east, and vice versa.
Since the weft is the circle of latitude, a closed circle with no head and no tail, the east and west directions are infinite. That is to say, if you keep moving along the lines of latitude in the direction of the earth's rotation, you will always be eastward, and there is no end; On the other hand, if you keep moving along the latitude against the direction of the earth's rotation, you will always go westward and endlessly.

The upper is from the north, the lower is from the south, the right is from the east, and the left is from the west; Northeast, Northwest and Southeast, Southwest angles forty-five.
The key to the direction is to look at the angle, east, west, north and south first recognize, and then look at what the angle is. The relationship between the east and the north and the east should be clarified. South-east, south-east, there is a relationship between angles.
North by West, North by West, the two angles are mutually congruent. South-West, South-West, the same is true. Set the direction and distance, step by step, don't worry. There are proportions between the distances, and the scales are the same to draw carefully.
A way to discern the direction
Morning: Everyone knows that the sunrise is east, we line up our hands, the right hand points to the east (sunrise side), and the left finger points to the sun and the other side is the west (sunset side), then the direction in front of us is the north, and the direction behind us is the south. "Face north and back south, left west right east".
Middle age: After 12 o'clock in the first year, standing under the sun and looking at our shadow, we have our backs to the figure, the direction of the shadow is north, and the direction of facing (the sun) is south. The left is west, and the right is east. The villages in the north are basically houses facing north and south because of the northern area.
Winters are cold, so "north and south" is to enjoy the sun for a longer period of time. Therefore, if you look at the orientation of the house in the north, you can distinguish between the southeast and the northwest.
Evening: Evening is better distinguished, as the saying goes: "The sun rises in the east, and the sun sets in the west".
Evening: Big Dipper.
The Big Dipper is made up of seven stars in the shape of a spoon, which is the brightest one ever, and we find the Big Dipper, facing its direction to the north, the back to the south, the same left, west, right and east.

The mantra of up, north, down, south, left, east, right, and west is as follows:1. Up, north, down, south, left, east, right, west.
2. Wake up in the morning and face the sun, with east in front, west in the back, north on the left, and south on the right.
3. The north and south are opposite, and the east and west face each other; Between east and north is northeast; between east and south is southeast; between west and north is northwest; Between the west and north is the southwest direction.
4. East-e, west-w, south-s, north-n (map).
The universe is an infinite carrier, and although the universe has directionality, it has no directional nouns. And the direction noun on the earth is actually created by human beings subjectively and purposefully. In order to facilitate human identification and cognitive direction.
It is a habit recognized by emperors and generals and ordinary people.
"Up, North, South, Left, West, Right, East" is only applicable to maps that do not have pointers, graticules. This is called general discernment.

When playing, write some characters on the eight sides of the inside, preferably with good people and bad people, you can write some well-known cartoon characters, such as Sun Wukong, Tang Seng, Zhu Bajie, Sha Seng, gourd baby, snake spirit, etc., it is best to account for half of the good and bad, and then ask the little partner to choose the direction of the southeast and northwest, how many times to choose, horizontal or vertical, and follow the steps after choosing.
It can be used as a children's toy, cultivate children's hands-on ability and logical thinking ability, replace plastic toys and electronic products to a certain extent, reduce the burden on the environment, and reduce the time when children are exposed to electronic products, and avoid eye damage caused by playing electronic products for a long time.
You can also write some rewards and punishments in it when you play, which can be combined with education, and write some things that children should do but are not willing to do, such as tidying up the room, letting children choose by themselves, this method is more acceptable than imposing some housework on children, and after the children have completed, give some rewards appropriately.

The content of the tips and tricks for distinguishing between the southeast and the northwest is as follows:
The mantra is: up, north, down, south, left, west, right, east.
Here's the trick: we don't wake up in the morning when we wake up facing the sun, east in front, west in the back, north on the left, and south on the right. The sun rises in the east and sets in the west. The mantra comes from the ancient civilization of mankind, which mainly originated in the northern hemisphere and is located with the North Star.
1. The Big Dipper, like a huge spoon, is easy to find in the clear night sky, and from the direction of the extension line of the two stars on the side of the spoon, there is a brighter star in the north that is the North Star, that is, square.
We Chinese live in the northern hemisphere, in the consciousness of the ancients, no matter whether the sun they see during the day rises in the east and sets in the west, it is always in our south, and at night to watch the stars, looking up at the Big Dipper, which symbolizes the emperor, in this way, "going up the north and going south" is also in line with the living habits of ordinary people.
Second, the results are immediate.
In a clear day, use a straight skewer perpendicular to the ground and stick it into the ground to form a shadow under the sun's rays.
Place a stone at the apex of the shadow, and after about 15 minutes, when the apex of the shadow moves to another place, put another stone, and then connect the two stones in a straight line, facing the south side of the sun and the opposite direction is north, the higher the straight skewer, the thinner, and the more perpendicular to the ground, the longer the shadow moves and the longer the distance to observe the cherry blossoms, the more accurate the direction will be.
Third, use moss, the dense side of the moss should be south, and the sparse side should be north.

The mantra to distinguish between the southeast and the northwest is "up and down, down the south, left and west, right, Wang Zi, Dadong, and vertical", and the tricks are as follows:
1.Houses: Houses generally have doors that open to the south, especially in the north of the country.
2.Trees: The south-facing side of the tree is usually leafy, brightly colored and smooth-barked, and the north-facing side is the opposite. At the same time, moss may grow on the trunks of trees on the north-facing side.
3.Protruding features: e.g. walls, ridges, stones, etc., which have a moist base on the north-facing side and may grow bryophytes.
4.Sun: The sun rises in the east and sets in the west.
5.Use the compass to get directions.
6.Use the map to identify directions.
7.Use trees to orient yourself: In the Northern Hemisphere, the south-facing side of the tree is generally more leafy, while the north-facing side is more sparse.
8.Use rocks: Where there are many rocks, you can also distinguish the direction by the growth of the rocks.
In short, to distinguish between the southeast and the northwest, you need to master some mantras and tricks, and at the same time judge in combination with the actual situation.
