Why is the southeast and northwest of the Book of Changes different from the southeast and northwest of geography books?
The directions of the Book of Changes are: upper south, lower north, Zuo Dong and right west.
The modern geographical orientation is: upper north, lower south, left west and right east.
Why is it different? Who is right? (Well, different perspectives, as explained below), what happened? Don't worry, I'll speak slowly!
Have you ever heard of an idiom? "Far and wide", so there is a pothole scenic spot in Hainan called "Tianya Haijiao".
This is the ancient orientation order, which means that the sky is the sky and the sky is the south; Down to the ground, the ground is north.
What do you mean by that? Still different. Are the coordinates wrong? In fact, it is the same as modern coordinates, but the perspective is different!
Modern and ancient azimuth coordinates are different. In fact, one is from the sky to the earth, and the other is from the earth to the sky.
This is a modern coordinate, and everyone knows it. North, south, left, west, right and east, no problem!
The picture above is the ancient coordinates. For example, we often listen to the jokes in movies: Zuo Qinglong, Right White Tiger, Former Suzaku and Later Xuanwu. There are many scales in art and mathematics, most of which are called four beasts, which can represent many things, and orientation is one of them.
Zuo Qinglong (the orientation represents the east, five elements of wood, spring),
Right white tiger (representing the west, five acts of gold, autumn),
Former Suzaku (representing the south, five acts of fire, summer),
After Xuanwu (representing the north, five elements of water, winter).
Summary: In fact, there is only a difference in perspective between ancient and modern directions, but there is no difference in orientation! In ancient times, the south represented the sky, so it was far apart. In ancient times, the south was seen below rather than above in modern maps, because the perspective was different from that of modern times, but their directions were the same. Can you understand what I mean?
As shown in the second picture, if the villain is the other way around, his front is the north. But in ancient times, we only looked at the villain from the perspective of Figure 2.
In fact, the difference between them lies in the opposite direction, but: if we look at the position with the characters before and after, the ancient and modern positions can confirm each other.
Typing by hand and tossing pictures by yourself, I hope I can help you!
