It is conceivable that this method, in addition to being used in the due south method, will also be used in the calendar.

That is, it is used to observe the winter solstice and summer solstice.

For this reason, if you use a long sword to observe, then this long sword can be called: Mo Evil.

That is, Mo Xian.

The name of the legendary sword Mo Evil, and the name of the Mo Evil Sword in Zhang Jingtao's hand, all came from this.

Even, with the orthographic method and the ability to make I-shaped strings with vertical angles, Ah Ah was able to use it to observe the east-west parallels.

This kind of observation is also very important.

For this reason, one of the later Zhang clans who was very good at this observation was given a surname by Ahe.

This surname is the surname 'Chen'.

The surname Chen is, of course, also surnamed Zhang.

Just like after this fusion, the people of the Baiyue tribe will all have the surname Zhang.

And he is proud of the surname Zhang who can get the meaning of bow length.

For this reason, in modern times, if anyone's surname becomes inexplicable and he feels that he can't find his ancestors, he will change his surname to Zhang again.

Or, whoever doesn't know his background will use the surname Zhang.

This recognition of ancestors has continued into modern times.

It must be known that the Buddha character representing the ancestors contains the word 'bow'. And Ah, it is Guanyin Niangniang, civilization, it is Guanyin! The surname Zhang is not the ancestor of the Chinese, and who will!

Buddhism will first call the name but not the surname, it is because all the Buddhist disciples have the surname Zhang, so they have the habit of omitting the surname.

Of course, this Buddhism is to say the ancient Buddhism, not the great changes of the present Buddhism, the ancient Buddhism is by no means a vegetarian Buddha, the ancient Buddhism, what is done is to benefit the common people.

In order to better spread the Chinese language, Ah He will use the surname giving model to make it easier for people to know and inherit the language.

Chen, with the display aside.

This is not near the ear.

Next to the display, in fact, it is an extension of the word "nai", but the woman's nai, naturally means that there are two identical and similar things, that is, two identical steps, and the word "丿" representing the body and water body is replaced by a vertical, which becomes the meaning of the continuous steps.

Only then can there be a display meaning of displaying similar items.

For this reason, this is also called observing the heavenly stems.

Chen Jiaqi's weapon is named exactly: Cadre!

As for whether the human body is also a type of water body?

Of course, it is a kind of water body, you know, seventy percent of the human body is water, of course, only theoretically.

Therefore, it is very clear that the word Chen is the meaning of Liedong.

As for the word Dong, no one can figure out the meaning of this magic word.

In fact, the word "east" is related to the astronomical technology contained in the word "positive".

The upper part of the east is an oblique cross, and contains a 'small' word, which means that after the oblique cross view, the most 'small' shadow is obtained, and then the horizontal vertical of this shadow is the east, which is very ingenious.

The need to use 'orthography' to determine the south is because the south in the astronomical calendar is not absolute, and only by orienting it with the meaning of the earth's axis will there be an absolute due south.

But this due south is difficult to determine in life.

The compass is only relatively southern.

From an astronomical point of view, the relative due south has been changing slightly.

What Ah needs is to determine the time and season by observing the sun and shadow.

It is conceivable that what she needs to observe is relatively due south.

And the head of the family in the audience naturally doesn't know much astronomy, and if he understands the Zhengnan Law, so does Feng Yu, so does Feng Yu, and only asks: "So, what is twenty-four hours?" ”

Ah He has already made all ethnic groups return to their hearts, and if he wants to spread civilization, he will naturally not be stingy, and immediately said it on stage.

But after using orthography, Ah Yu divided the day into upper 5 and lower 5, her beginning, in fact, is 1 o'clock, the middle is 10 o'clock, and the evening is 5 o'clock.

In such a pentatile algorithm, the two zeros at the early morning and evening heads will not be counted because the time of black and white alternation is very uncertain.

Therefore, this is 10 points, which is in line with Ah's ten-finger counting method.

Hearing this, Zhang Jingtao unlocked the mystery of the word 'nine'.

Nine, it is the word that appeared after Ah Yu determined the day of the oblique cross to 10 points.

After creating the numbers seven and eight, she finally planned to count them with her fingers instead of using only 5, so after creating six, seven, eight, and nine, she rearranged the order of the numbers to these ten points in time.

Her arrangement is that the first point in time becomes 0 o'clock.

At the last point of the day, it becomes 9 o'clock.

And in the beginning, Ah Ma does not look at time from the perspective that the first day is 10 time points, and the second day is a total of 20 time points.

In her opinion, the concept that the next day is still 0 to 9 o'clock, not 10 to 19 o'clock, this concept is not surprising, just like modern people, who also look at time in this way.

Only the accumulation of days will be counted.

Therefore, Ah He sees the last point of the day as a point in time when time is about to return to 0:00 the next morning.

It is reversible and repeated.

Therefore, the nine characters composed of 'oblique cross' and 'Shiba Inu tail' are a mantissa in the oblique cross of the sun, and after it ends, the count will go back to 0:00 the next day like the tail of the Shiba Inu pointing in reverse, and the next day, start the time again at 0:00.

Text: Nine, that's how it came about.

It is conceivable that the mathematical symbol 9 also came from this way.

The number 9, judging by the strokes, is a very clear meaning of turning around and starting over.

However, the progress of math 9 is that it can represent the decimal system, and after it, it can be 10, that is, 20, and it does not use backwards, but uses backwards, and starts from the beginning.

So, how early did the Chinese people understand the base system?

Just 268 million years ago, Ah Ha invented the number 9.

The number 9 clearly expresses the mathematical model of the decimal system.

It's just that Ah has this method, but at night, he still can't observe the shadow of the sun.

For this reason, with the candles in the bowl and the "bowl" of the night, Ahma, who is more concerned about the time of the night, plans to divide the time of the night in his own way.

Naturally, she used candles.

Therefore, the wax word, in addition to the meaning of the bee insect with a common hole, also carries this meaning.

The double cross contained in the wax character is the meaning of dividing the time of the 'day' with the number 'ten' and the image of the number 'ten'.

It's just that this day is the whole day.

For this reason, the word day, in fact, can also be divided into the earth platform and the earth platform of the Chen image, that is, the two mouths overlap, that is, the observation of the sun on the front of the earth, and the observation of the sun on the back side of the earth, combined into one, is a complete day.
