Therefore, the word "Xi" sound that can represent the sunlight shines on the back of the earth.

Therefore, in the past, it actually refers to two very close times.

The true meaning of the past is that it was only a while ago.

Just like, how good we were in the past, today, you turned against each other, which means that the other party changes his face quickly.

With candles, Ah Hee thought that even the evening was counted. It is conceivable that the previous sun shadow calculation method, which was 0 in the morning and 9 in the evening, had a little problem.

That is, according to Guanyin's law, it is not the real night. In fact, it is the moment when the sun has already revealed a trace of sunshine. In terms of the sky, it has actually been bright.

It wasn't really night at 9 pm. Although the sun was gone, it was still far from dark.

However, the real excessive night time of these two heads is sometimes long and sometimes short, which is not easy to distinguish.

For this reason, after Ah Yi thought of the Chen Si Dharma, he only drew a horizontal line below the two at 0 o'clock in the morning and 9 o'clock in the evening to indicate that the horizontal line was below the night.

In this way, there are two more time points, and the "once" time from night to day and then to night becomes twelve points.

It is not surprising that Ah Yi easily decided to use twelve points to calculate the time. As the ancestor of the "moon length" who likes to watch the moon for a long time, she has always known that there are twelve months in a year. In order to make people remember twelve months, she probably uses twelve hours to make it happen.

This shows that Ah Hee has long had the concept of decimal and decimal.

When Zhang Jingtao heard this, his heart moved, and the word "Six" was instantly cracked!

The six characters record this astronomical change.

It is the appendix of the sun shadow that light and shadow walk in one day for twelve hours. Use the word "eight" to separate the meaning of separation. Divide these twelve time points into two, and there will be a quantity of "six".

Extremely exquisite astronomical texts!

It can be said that he does not know astronomy, and does not know six.

If you want 666, of course you have to understand astronomy.

After that, Ah Yi didn't bother about where the intersection of night and day was, because she knew very well that it was changing all the time. For this reason, it was very simple. According to the principle of Chen Si and the mirror, she copied and reflected the twelve points, even if it was the hour of the night.

So, Ah Hee has a twenty-four time table that is slightly different from the modern clock.

There were only twenty-four hours.

And, for some reason, Ah Hee has already mastered the usage of pi and decimal points.

For this reason, she thought that the time before sunrise and sunset was really difficult to calculate, and the time required to calculate the time was better to make people feel more time-sensitive. She was very arrogant and divided the twenty-four points of the day evenly as time.

"I want to serve you so that everyone's lives can be more regular, and there is no need to accommodate the changes in light and darkness every day!" That's what Ah He said about this completely artificial division method.

After saying that, Ah Yi wiped the positions of the 24-minute points on the blackboard again, and then, at 12 noon, he wrote a big word ‘0’.

He also said: "But, such a twenty-four hours are good, but if you want to accurately count the time, you must use the most accurate sun shadow at noon to correct the time difference more. So, after considering this, I still put the time of the day. Asxs. at noon, and still use the time of the afternoon as hours and the time of the morning as hours to use the time."

Blood Quartz was so sensible that he could not help but say, "But there are too many points on it, and his eyes are blurred."

Everyone was about to scold Blood Quartz for not taking the liberty, but saw Ah Yi smiled and said, "Yes, although the twenty-four-hour method is very good and intuitive, there is a huge problem for us people in the prehistoric world, that is, it is not easy to remember and express. Therefore, although the twenty-four-hour image looks very intuitive, it is not intuitive to use."

Xue Quartz was very happy and nodded, "Yeah, well, let's talk about it, time may be more subdivided. Twenty-four points are too dense, and it is not conducive to subdividing in one point of time."

But he actually put forward a very constructive perspective.

After dividing a circle into twenty-four parts, it is indeed difficult to subdivide it in minutes.

Ah Xixi nodded, removed twelve points, one by one, and said, "Yes, as Ying'er thought, I also thought of this problem, so I used the concept of time to hide all the time. And merged the twenty-four points into twelve time points."

Then he smiled and said, "I guess, the counting method of only two more fingers is something you can imagine, right?"

Everyone in the audience responded.

This time-sharing method is exactly the same as modern clocks. It starts with the south method from noon, and then walks around, and the twelve hours completed in this way are counted as hours.

Wait until 0 o'clock in the evening, walk around and noon the next day. The twelve hours completed in this way are counted as the hour.

It's like there's a mirror under these twelve time points.

So, can people who don’t understand these things, those who don’t have five-stringed zithers, those who don’t have six words, and those who don’t have the foundation of twelve-civilization, invent clocks?

Funny, right?

So who invented the clock?

Chinese people!

After counting the time with the burning speed of candles of fixed thickness and wax hearts at night, this method of falling slightly due to combustion caused by burning is called Si Shi by Ai.

For this purpose, use silk sound.

Even the horizontal curved hook ‘??’ is not read by the hook, but by the si.

The word "Si" means that it slowly descends along a plane in a lake body, causing the large surface body to gradually shrink into a small lake body until it enters the bottom of the lake body and completely consumes the lake body.

This method of making characters has the meaning of T and also has the usage of salt.

Therefore, this horizontal curved hook ‘??’ has the meaning of fire slowly burning and the meaning of phantom.

Even the word "illusion" comes from this.

The next word 一一 in the fantasy is like a silk spinning movement. An object is similar to an object, with the sound of "shaking". However, the object below is a shadow. For this reason, the word 一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一�

If the upper half of the character "子" is separated, then the same one has the meaning of moving the sun shadow into a daytime.
