It seems that the weather has entered autumn now, and according to the time, it should be around August or September in the Gregorian calendar or July in the lunar calendar.
However, there was no calendar in this primitive tribal era, so there was no accurate year, month, and day to record time.
But primitive people can also roughly divide months through changes in moon phases, and divide seasons and years through changes in plants.
However, no precise relationship has been established between seasons and months.
The alternation of day and night is one day.
The moon waxes and wanes once every month.
The vegetation dries up and flourishes for a year.
Spring blossoms, autumn brings fruits, summer is hot and winter is cold, these are the changes of the four seasons.
All these concepts of time still remain in the most primitive sense of ignorance.
Therefore, it is impossible to accurately calculate the exact time of each event.
The simplest thing is age, no one can accurately know how old they are.
At most, after each person is born, the mother will carve a mark on the stone wall every year, and for every additional person, the mother will also carve a mark on her special staff, but the clan members are alive and dead, and her stick
The staff was densely engraved with marks. Not only could others not understand it, Xu Chen could believe that Muba himself was confused and could only rely on guessing.
Xu Chen even suspected that Muba couldn't count.
Because the people in the entire tribe are not very good at counting, they usually count their fingers and pile pebbles. They judge the size of things by judging the pile. Adults can usually count to ten, because they only have ten fingers and are bigger.
The numbers are beyond the range of organs they can draw from.
Of course, the one in the middle of a man does not count. It is a semi-hidden number, and its state is not very fixed. It is in an uncertain quantum state between one and non-one.
If you don’t know how to count, you naturally don’t know how many days there are in a year and how many days in a month.
Recently, Ye has learned to use larger numbers and can also perform single-digit addition and subtraction calculations. Therefore, she is very interested in the number fifteen that suddenly appeared from Xu Chen. Xu Chen also decided to use the waxing and waning of the moon to teach her simple
's calendar.
The calendar based on the changes in the moon phases is called the lunar calendar. The lunar calendar is an inaccurate dating method. The years, months, seasons and times are not fixed. It is not suitable for guiding agricultural production. However, it is the simplest for primitive people who have no astronomical knowledge.
And the easiest solution to identify and accept.
Xu Chen actually doesn't care whether the year, month, and day are accurate. The main thing is that he needs a calendar like this to record the time. Otherwise, as the time travels longer, he will gradually not even know how old he is.
Sad.
With the faint moonlight, he first drew a circular moon phase change diagram on the stone wall. Clockwise from zero to six o'clock, it is the waxing moon state, and from six o'clock to twelve o'clock, it is the waxing moon state.
"Understood?" Xu Chen turned around and asked after finishing the painting.
Ye looked at it seriously for a long time and shook his head.
Xu Chen had no choice but to point to the full moon at six o'clock in the moon phase, and then pointed to the full moon in the sky.
Ye understood instantly and nodded vigorously.
"fifteen!"
Xu Chen smiled and wrote down the two numerical symbols ix on the full moon at six o'clock, then moved his hand counterclockwise back to the first quarter moon diagram at three o'clock, wrote down the two numerical symbols seven and eight, and then pointed
Looking at nine o'clock, write down the numbers twenty-two and twenty-three, and finally write thirty in the blank zero position.
After finishing writing, he circled the entire moon phase picture with his hand and said, "One month, you know?"
Ye shook his head blankly.
Xu Chen:……
It's so difficult for me, I can't even understand such a simple picture.
Xu Chen had an urge to die.
But when I think about it, I feel calm again. I am facing primitive people who still wear fur, drink blood and wear furs. It is exactly like teaching astrophysics to a kindergarten friend.
Although Ye is more than ten years old, he has actually just learned single-digit addition and subtraction, and can barely count numbers within thirty.
So he could only patiently continue to explain the relationship between moon phases and time.
Fortunately, Ye was able to accurately recognize numbers, and he was also clear about the changes in the moon. Although he was confused after the explanation, he roughly understood it.
Time is like water, and the night is getting darker.
The time is estimated to be around nine o'clock in the evening.
Ye yawned.
It is obvious that learning makes people sleepy, especially courses that they do not understand.
Seeing Ye rubbing his eyes and looking drowsy, Xu Chen had no choice but to drop the charcoal and said: "Sleep!"
"Oh!" Ye entered the cave in a daze.
Xu Chen looked helpless, then looked up at the deep night sky and the bright moon alone and continued to be in a daze.
Although I have traveled through time for more than a month, I am still out of tune with this era.
I don't know what the point of doing this is.
…
When I woke up, it was already bright again.
The weather is a little gloomy today.
The wind blowing on my body also feels a bit chilly.
It’s really autumn!
Xu Chen couldn't help but sway slightly.
Ye was squatting alone in front of the stone wall by the fire pit, concentrating on the moon phase chart above.
Seeing Xu Chen coming out, she quickly stood up and helped to serve the rice.
Xu Chen came over after urinating, washed his hands, face, and mouth, sat by the fire pit and ate, pointing at the moon phase chart with his chopsticks and asking, "Do you understand?"
Ye nodded slightly ashamed but quickly shook his head.
Xu Chen didn't ask too many questions. It didn't matter whether he understood or not, but this kind of enthusiastic learning attitude was very good, much better than a group of little savages who looked like fleas all over their bodies when class came.
Right now among the entire tribe, Ye is the one who is more interested in learning.
Although other savages would often come over to take a look out of curiosity, they became increasingly confused by the increasing number of strange symbols on the walls.
Xu Chen once tried to ask Gu and Ju to join in and study together, but they only studied once and then never came again. As soon as Xu Chen heard the word study, he ran faster than a rabbit.
They would rather hunt, dig, carry rocks and collect firewood than sit still and read various obscure symbols.
Xu Chen couldn't force this kind of thing, but fortunately, as time went by, the people in the tribe gradually learned many of the words he innovatively invented. If this continues, sooner or later a complete language and writing system will be formed.
.
He is not in a hurry about this matter and can take his time.
After breakfast, Xu Chen took out the rolled loom and found a flat place to sit down and continue weaving.
But when I sat down, I realized that the ground was very cold, and I couldn't help but grin and take a few breaths of cool air.
The weather has been getting colder day by day since autumn, and sitting on the ground every day is not enough. However, there are too many messy things in the tribe, and everything is lacking. Fortunately, I, a savage, have a thick skin and rough flesh, which is more tolerant, so I can endure it for the time being.
Seeing Xu Chen starting to weave again, Ye ran over and squatted beside him to watch carefully.
A group of children who were feeding the pony saw that Xu Chen was making something new that they had never seen before, and they immediately swarmed around.
Tie the waist rope and step on the prayer stick with both feet.
Lifting, dividing warp, shuttling, beating up.
Click, click, click. With the gentle tapping of the weft knife, the number of twine continued to increase one by one.
As he repeated the simple steps over and over again, Xu Chen became more and more skilled in his movements.
A group of children were surprised by this thing that was too complex to understand, and they could only scream in various exclamations, especially a few little girls, who couldn't take their eyes away.
"Understood?"
After knitting for more than ten minutes, Xu Chen raised his head and asked with a smile.
"Yeah!" Ye nodded seriously.
"Try it!" Xu Chen stopped, released his feet and untied his waist rope.
Ye shook his head nervously, but with Xu Chen's encouragement, he still sat down. Then with Xu Chen's help, he tied his waist rope and stepped on the prayer stick.
"Don't be nervous, the first step is to lift the heald rod... insert the warp rod... thread... beat the weft..."
Xu Chen carefully taught the weaving movements step by step.
Although Ye was nervous, he had already become familiar with the steps after watching them for so long. He was just a little confused when he suddenly got started. However, after Xu Chen carefully taught him a few times, as he gradually became familiar with the steps, his movements gradually became smoother.
Seeing that Ye was able to complete the weaving action on his own and became more and more proficient, Xu Chen smiled with satisfaction.
Spinning and weaving is relatively simple and boring, and only a careful and gentle woman can do it.
The most important thing is that this job does not require much physical strength, and there is no danger. It is very suitable for women, children, the elderly and the weak who cannot do heavy work.
After the emergence of spinning and weaving, tribal women will be busier in the future, but they will also create greater wealth.
After Xu Chen taught Ye to start weaving, he called Gu Heju, who was making tools with several adults, to come down the mountain with him.
"Eh~"
Seeing Xu Chen carrying the cane basket on his back and about to leave, the pony tied to the edge of the woods kept stamping its feet and neighing.
"Let's go, I'll take you down with me!"
Xu Chen smiled and untied the rope. After thinking for a while, he asked Gu to find two rattan baskets and tie them together with ropes to make a basket-like shape and place it on the pony's back.
"Eh..."
The pony obviously felt uncomfortable with the things placed on his back. He stomped his feet, raised his head, turned around and neighed, and even turned around to bite off the rattan basket with his mouth.
Xu Chen stroked and tickled him for a long time, and then the little guy slowly calmed down and reluctantly accepted these two things that made him uncomfortable.
The rattan basket is not heavy, just a little uncomfortable.
Xu Chen didn't put anything inside, just to let the pony slowly get used to the feeling of carrying something on his back.
When taming any wild animal, it's best to start young.
Although the pony would still bite back from time to time on the way down the mountain, or deliberately jump and jump in an attempt to get the rattan basket off, Xu Chen either comforted him carefully or used some weeds to seduce him.
Let it succeed.
So after several twists and turns, the pony began to accept its fate, and finally successfully carried the two rattan baskets down the mountain.
