After the birth of such a principle, some of the opposite arguments were selectively forgotten as a matter of course. The important historical material "Bamboo Book Chronicle" is like this, and the theory of drilling wood to make fire has also been largely ignored. So much so that some cynics believe that in modern times, we first learned from Westerners about drilling wood for fire, and then searched around from our own classics, and finally found relevant records in the garbage heap of history.

We generally think that the cynical statement is not entirely unreasonable. But as far as this matter is concerned, the cynics' claims are only theoretical. In order for the majority of students to be able to succeed in their studies, we still advocate that some cynics say: "Please let down your guard and accept the poison willingly." ”

Therefore, things like "Guan Yinzi and Erzhu" that describe the worldview of ancient people, although there are many absurd and unreasonable things in it. He should still be exalted in historical circles. After all, he managed to escape the selective "massacre" of the so-called Great Confucians in the past dynasties and successfully survived.

We should treat this kind of book with the same attitude as we do with giant pandas.

The giant panda already has many limitations in terms of physiological functions, and several species that are called living fossils along with him, such as beaked lizards, are actually the same as him. If we compare close relatives horizontally, we should be glad that they are still alive. They have not evolved as well as insects and rodents in terms of adaptation to modern survival. This has many similarities with the ancient texts that have been selectively forgotten by Confucianism.

Biology needs diversity, and history may not need it. But we don't care if we're selfish.

History must have its diversity just because we need it. Because we cannot understand history from only one aspect, as long as we want to understand history in all aspects, we must ensure its diversity.

But there is only one real history, and with diversity, who is his true body? In the past, it was those Confucian scholars who selectively forgot that caused historical diversity, and now it is we who need to restore the only true history through historical diversity.

It's a fucking irony!

Poor history is having to show different demeanors because of the needs of different people.

What kind of behavior is this like?

Prostitute-Girl!

History is a prostitute!

But the real lowly existence is not him, he is forced to do so. The truly lowly ones are us. Humans, humans in different planes and planes.

Today we are laughing at the Confucians for selectively forgetting, and tomorrow our children and grandchildren may laugh at us for treating everything as history, when in fact, without those things, we will live better.

The devil knows what will happen in the future, but Hu Zhao knows what will happen in the next few minutes.

He was ready to eat delicious rabbit meat right away.

After crying bitterly, Hu Zhao and Guan Ning both regained their composure. After some thought, they decided to do the cruel thing to the end.

So they took the rabbit that had turned into a hedgehog and gave it a barbecue.

They were still sympathetic just now, but now they have shown the diversity of the menu of the species at the top of the food chain.

It's getting dark, the solar panels have been installed, and the next thing to do is to light a fire and cook. The solar cooker is not needed for the time being, because the panels are used to generate electricity. I didn't bring any supporting facilities for cooking.

So most people choose to go back to the crossing community to eat, and only a small number of people will eat dry food at the camp.

Guan Ning and Hu Zhao have a special barbecue feast waiting for them.

"Speaking of which, we've been here for so long, and we haven't even made a clear distinction between east and west, north and south."

Hearing Hu Zhao say this, Guan Ning pointed to the sun that was about to set, and said with a smile: "Isn't that the West over there?" Relative to the east, I will look for the North Star later, and I will be able to distinguish the north and the south. ”

Hu Zhao shook his head and said, "You don't understand what I mean. The lord asked us to draw a more accurate map. So I think we still need to be more precise. ”

In fact, there are many ways to distinguish the direction in the field. If you don't need to use a precise measuring instrument, the easier way to do this is the rod insertion method.

Stick a pole straight into the ground and mark the end of the projection where the sun shines. Let's assume point A, and after a while, we make a point in the same way, let's record it as point B. After linking the AB connecting points, you can get an east-west line segment. One stop on the left, west, right, and east, that is, facing north. In this way, there are four directions: east, west, north and south.

As for the south, my friends have higher IQs than me, and they can make up for it automatically.

However, this method has a relatively large error due to the difference in time. At noon, the angle of view of the sun is relatively high, the shadow is shorter, and the change is relatively slow, so the direction measured by the above method is still relatively accurate. But in the afternoon, I don't know what the slope looks like.

"I see. Let's wait and see the stars. ”

Hu Zhao said that looking at the stars is also very reliable when discerning the direction in the wild. As long as you can find the North Star, and then you can stop there, and after facing the North Star, you can only be sure that it is left, west, right, and east.

Whoever asks me again what is going on in the south, I pick up the cat's tail and pump it to Saturn.

As for how to find the North Star? Many people must know this.

Since the North Star is almost facing north, it is very important in terms of orientation. There have been many ways to orient yourself with it.

This star, which was called Gou Chenyi or "North Star" in ancient China, should be called α Ursa Minor in astronomical circles today. Although his absolute magnitude is not low, his apparent magnitude is not high. So if you want to find it directly with the naked eye, you have to be familiar with the mystery of the old fritters. In general, it is not difficult to see him, but it is more troublesome to confirm her.

The most common method is to use the Big Dipper to find him.

The Big Dipper belongs to the constellation Ursa Major and is similar in shape to the seven bright stars of the Minor constellation, but it looks much brighter. If you look at the distribution, both have a 3+4 structure - that's what I'm joking about - and the useful part is the outer edge of the spoon in the "4".

Two stars on the outer rim, one at the bottom of the spoon and the other at the top. The old-fashioned way is to make a line segment from the bottom to the top of the spoon, then extend it five times to find the North Star.

But here comes the problem again. It's approaching winter now, and Ursa Major is not easy to tell in winter. So Hao Zhao had to use another constellation to help. That's Cassiopeia.

If you haven't heard of Cassiopeia, you can ask Du Niang. Don't think that there are only Aries, Gemini, Scorpio, or anything in the sky. This is something that came out of listening to astrological nonsense, in fact, it is better to look at those things in ancient China, which is more nonsense than this thing, but it is more interesting.

Cassiopeia looks like a leaky ship. In my personal opinion, he looks even more like a boat than a beautiful queen than a southern Boat.

His "main shape" is five stars posing in the shape of "W". When using it for orientation, you should first estimate the width of the bottom of the boat, which is the width of the gap below. Then extend it "from the bottom up" by two widths, and you can find the North Star.

The accuracy of Polaris is still relatively high. It is much more accurate than some so-called empirical statements that seem to be earthwork.

Although there is an angular deviation between the North Star and the geographical North Pole, he does not indicate due north, which has been proved by Shen Kuo through unremitting efforts in ancient China. It seems that there is also a number of years before the West in this regard, but I don't remember exactly.

As for those soil methods, what kind of big trees grow independently, the southern side of the foliage will be denser. First of all, trees in the southern hemisphere will not agree with this view, and secondly, the density of the branches and foliage of trees is also affected by factors such as wind, so this is not always the case.

Another so-called empirical statement is. After cutting down the large trees that grow independently, the direction of the sparse growth rings is the south, and the direction of the denser is the north.

As for this method, first of all, it can only be used in the northern hemisphere, and secondly, this phenomenon is not obvious in the tropical regions of the northern hemisphere. Secondly, some trees naturally like to grow on the north slope, and people don't bask in the sun, so it would be a bit unreasonable for anyone to explain it with any kind of photosynthesis. The most important thing to remind is that if the position of the cross-section, or the height of the same tree, is different, the sparse direction of the growth ring will change. This has been proven in practice.

Speaking of which, it's all heavenly stuff that is more reliable. Nothing on the earth will do. Therefore, if you really want to practice, everything that can be used on the ground to distinguish the line of defense, including residual snow, daily wind direction, etc., can only be used as a reference.

What is truly trustworthy is something in the sky. It's not about Polaris, it's about Sputnik.

Now Hu Zhao is very much looking forward to seeing the first artificial earth satellite belonging to Dayue in the night sky during the Warring States Period.

GPS, Beidou or something, as long as there is one in the sky, it will be more convenient to unify the world even in the future.

I heard that Shen Yu specially asked to join several aerospace science and technology companies in the negotiation of establishing a celebrity group, and I don't know if they are busy producing satellites now, let alone when they will be able to use them. From being poor and white to being a satellite in the sky, I don't know if the Dayue Kingdom, which had just settled in the 11th century when the productive forces were backward, would take less time than the Splendid Country.

Hu Zhao suddenly looked forward to the future.
