Why are all compasses but few compasses?

The ancients pointed out that there was no compass in the north, but by looking at the North Star. China is a country with advanced astronomy, which is located in the northern hemisphere. Long, long ago, the ancients were interested in the stars, planets and constellations in the sky and were diligent in observing them. They are very familiar with the Big Dipper in the sky. Four of the seven bright stars form a barrel shape, and the other three form a barrel handle; Moreover, it is easy to find the dazzling Polaris located in the North Pole with the Big Dipper. Pointing north with Polaris is the common sense of China people, and it is also the tradition and habit of China people.

With this symbol that can point to the north, nothing can compete with it, nor is it allowed to compete with it, just as the sunrise points to the east. Because of this, the "ancestor" of the compass was also made into the shape of Beidou No.7 star, called Sina. It may be because of this tool called "Sina", so later everyone got the saying of compass. After getting used to it, in fact, no one cares why it is not called compass, because the north and the south are opposites, and if you know the north, you must know the south. In addition, in the ancient culture of China, the south was Yang and the north was Yin, and all the living people respected Yang. The emperor sat facing south, his back facing north, and the doors and windows of the main room facing south. So point out the direction, and the south is the priority. Compass is the name adopted in the traditional design of China! Therefore, the compass was invented by China. But in terms of orientation, we call it a compass. Because the red pointer always points to the north, its official name is actually the compass.

And the pointer marked above points to the north, which is also internationally unified. In China, it is traditionally called a compass. Because in ancient China, the compass took due south as the reference direction, so it was called Sina, and the small compass was called compass. This address habit continues to this day. So in our country, many people call it a compass.

In fact, this is not a good habit. In fact, some users often buy a compass, thinking that it indicates the wrong direction or is misled by this bad name. If the compass was not found at that time and needed to be used at a critical moment, then this mistake may bring great danger. Therefore, it is necessary for the compass to correct this bad habit.
