In fact, Zaozi uses the upper and lower order.

The sun rises above and the sun sets below.

The cross means to separate morning and afternoon.

Therefore, the sun above the cross represents morning.

However, at some point, she added four strings to the five-stringed qin, turning it into a nine-stringed qin.

The lotus platform, which is flat and unobstructed, was first used by Ajie to observe the shadow of the sun. Therefore, according to the Zhengnan method, Ajiu set his finger on it every ten days to set the Zhengnan position.

Guidelines for the South.

The latest guide line she drew just the day before yesterday was just right for use.

Yes, the position of the earth's true south is always changing a little.

This is rarely understood.

At this moment, after the rim of the nine-stringed qin is placed along this guide line, the bamboo stick on the head of the instrument is pointed towards the south, thus creating a fixed observation position.

Indeed, it is very effective to observe time in this way.

Take a look at the guide lines carved on the stone platform. There are more than 80 guide lines. It has been more than two years. For this reason, these guide lines have become very useful as a reference.

Therefore, Ah Hui no longer has to wait for noon to determine due south, he only needs to refer to the previously determined guide line.

The ape-men from the Chu region are already very sensitive to seasonal changes, much more sensitive than the savages in the south, and this is even more true for Ah Hui.

She roughly knew that two years had passed.

It was with the concept of reincarnation in her mind that she tried to carve out a guide line for observation in the next year.

After all, Zheng Nanfa is very patient. Every time at noon, she would sit on the stone lotus platform and watch Guanyin for a long time. She would also use two chopsticks from time to time to compare the length of the sun's shadow, so that she could compare the shortest sun shadow line.

and due south location.

Zhang Jingtao discovered that this is another meaning of the word "hand". For this reason, the word "hand" is pronounced as "shou", which means to guard that "inch" of time.

It can also be seen that the south of Chu is too hot and the four seasons are not clear enough. For this reason, the savages are not sensitive to the seasons. This is also the reason why they have not developed civilization in modern times and have to be civilized.

However, at this moment, Ah Hui looked at those lines and became surprised.

"Huh? Huh?" kept coming.

She didn't know why she was surprised, but she didn't care that there were so many people around her waiting for her to explain the time issue.

But Zhang Jingtao at least knew that Ah Hui had definitely discovered something and was not pretending to be profound.

You know, Ah Hui’s understanding of astronomy has already surpassed all modern scientists.

It has to be said that modern scientists are all bookish. Who has the time to really observe the shadow of the sun day after day?

Just imagine it based on the book, it’s just learning.

Who knows if it’s science fiction anyway?

As long as you speak inscrutably and come up with a bunch of new names and data, people will believe you.

Of course, most scientists themselves do not know that they are actually playing science fiction in a ridiculous way. In their opinion, they are speculating and deducing, but they do not know that the books they believe in are themselves wrong.

Therefore, after they believed in these sciences created in an idealistic way, they chose "wrong books, wrong theories, and wrong formulas" as objective references and deduced and generalized.

As a result, the conclusion drawn seems to be logical and mysterious, but in fact, it is pure science fiction, or wrong science fiction.

Just like the wrong pi, it can be applied to the circle itself, so it seems very logical.

For example, they can't figure out why when the sun and moon shine together, when viewed from the earth, the moon is not blocked by the earth and is completely exposed to the sun, but this is only mentioned in all the books.

The reflective sphere only shows half of the moon.

It doesn't even show the full moon.

Shouldn't it be total reflection?

It is conceivable that how can modern scientists figure out how the earth rotates?

Of course, when looking at the moon from the earth, there should be a slight angular deviation, but even if there is a deviation, what one observes should be a full moon that is close to a full moon. However, what people see is that this moon is only half a moon.

Such a moon is really amazing. No one in modern times can understand why, but I know why.

Because Ah Hui has no books to refer to, she can only gain true knowledge by observing nature on her own.

Nature does not lie. Zhang Jingtao once heard Ah Hui say that from some recent observations, she had always wanted to know the reason why the moon is half-moon when the sun and moon shine together.

But when Zhang Jingtao asked her carefully, Ah Hui refused to tell her because she said there were still some things she didn't want to understand, and she had to understand them all before she could tell Zhang Jingtao.

At this moment, after looking at the lines on the lotus platform for a while, Ah Hui seemed to have solved her doubts. She clapped her hands and carved a long number '1' on the stone platform, and put the 36th guideline on the stone platform.

A few lines behind the line count as another year.

Undoubtedly, Ah Hui was so surprised at this moment because she could finally distinguish one year clearly through Guanyin.

For this reason, Ah Hui looked at the '1', thought about it, and marked the pronunciation "yi" on it. Undoubtedly, this vertical line demarcated astronomy according to the vertical line in the character "十".

From then on it became the number 1.

Then, Ah Hui enthusiastically explained the time to the girls.

As Ah Hui spoke, Zhang Jingtao became nervous.

Because Ah Hui’s explanation contains the reason why she thought of using sunlight to tell the time.

This will of course mean that the surface of the lake is "one", and the sunlight from the west hitting the lake is a "slanted cross". Then, if the light from the east is also included, then the word "big" will definitely be involved.

If you mention the word "big", then it might immediately cause a change in time and space, and your soul may fly to the Warring States Period again.

So, if he faints at this time and turns Fu Xi into an idiot again, it will undoubtedly make it more difficult for the Silk tribe members, who are all girls, to deal with the oil-eater, but they still have to take care of him who is like an idiot.

However, looking at the expressions of the clan girls around him, Zhang Jingtao could not interrupt, otherwise it would affect their trust in Ah Hui.

Moreover, he cannot tell A-Hui his true situation, otherwise it will affect A-Hui's way of thinking.

In desperation, Zhang Jingtao could only try to think of what words should be written next on the Jade Guanyin in the sea of ​​consciousness.

While he was thinking hard, he just listened carefully to Ajie's explanation.

Because Ah Hui's explanation may have given him a hint.

So, I heard Ajie say that when she wanted to record the time, she couldn't decide what to use as the starting point of the sun. The only base point seemed to be the due south point, so she took the due south point as the starting point.

base point.
