They lived in the cave next door, and there was a hole between the two caves.

They have done a great job in digging holes, and they are fully entitled to this treatment.

The firewood ring is very skinny, and from time to time I will poke my head over to look at it.

The Erha are more energetic, they like the hole the most, and the fat ha sometimes squeezes out the firewood circle and pokes his head over to see.

If they want to poop, they will go to the sand pit that Ah has made in another small cave outside.

There are often bamboo leaves, so that these poops can be rolled onto the sand bamboo leaves, and then swept into the bamboo shovel-shaped dung table with bamboo branches to get into the formal dung hole.

At this time, it was daytime, and Ah Ha was going to feed herself and go to the farmland she had built.

Yes, farmland.

Because Ah He is a silk tribe, he is used to domesticating to get fur and meat; will also make potato biscuits as food storage; Small animals are often used to test whether plants can be eaten; I also planted a lot of bamboo and bamboo shoots nearby, and found that bamboo can continue to grow.

Therefore, naturally, without daring to go too far away from Fuxi, the aunt dug up some plants found in the distance, such as potatoes, peanuts, sweet potatoes, etc., and transplanted them to a soil slope not too far from the cave entrance.

But that's not farming, Ah He's original idea was still just to find and save the plants that the little animals had eaten.

This is also Chai Quan and Chai Mei are very good at fishing, and there are a lot of fish in the lake in many seasons, and a lot of dried fish can be saved, so she has the conditions that she does not have to go too far.

It can be seen that the role of domestic beasts cannot be underestimated.

For this reason, Zhang Jingtao also found that Shiba Inu is a very self-respecting domestic animal, because since ancient times, their hunting ability is extremely strong, and their dependence on humans is relatively small.

Therefore, many owners tease the Shiba Inu a little, and the Shiba Inu will often bark its teeth at the owner, indicating that it is very powerful.

However, in modern times, if it becomes a stray dog in the city, it does not want to live.

Among those plants, there are also wild rice, wheat, and even dog tails.

When Ah Ah eats them, she does not eat them dried, but eats them fresh, although when she was in Chudi, she found that dried things were easier to preserve because of baking potato cakes, so she dried them.

But this is not Chu Land, there is no fire, she can't grind the dried grass seeds, add water to make puree, and make cakes to eat.

The mud at the bottom of the hillside is a muddy area created by nature, and it is very easy to support plants.

There aren't too many of them, but you can still find some in many places in the swamps.

For this reason, a few months later, Ah found that the potatoes had become much better, so this little girl who was good at thinking began to grow seriously.

In the past two years, which plants are easy to grow and can adapt to the weather, but also make Ah He, who already has a good feeling for the four seasons of the year, have a deep understanding of the relationship between seasons and plants.

Without astronomy, there would be no agriculture, and there would be no human civilization.

The reason why human beings have been able to drag so far is because of agriculture.

Farming is guaranteed, and when everyone feels that it is not a problem to survive, human beings can pull it up and start playing the game of 'forgetting agriculture'.

For this reason, although Ah is an ape-man, he knows very well that without astronomy, he can't think of decent agriculture.

So, she followed the method of creating the word 'one', and then she didn't do it, and wanted to be the prince's long qin.

I dug some small holes in a large piece of bamboo one meter long, inserted a row of small bamboo sticks vertically on it, fixed it, and pulled the parallel twine of the five gongs as a comparison baseline to observe the shadow of the sun.

In the meantime, the length of the bamboo stick exposed is the length of Ah Mu's finger, which is exactly five centimeters.

The reason why the female finger is called the mother is that this finger is like a comparable 'female ruler' mold, so as to obtain many 'child lengths' of the same size.

Of course, after determining a five-centimeter bamboo stick, Ah He's all used this bamboo stick as a ruler.

The method of observation is to make the end of the bamboo stick with the bamboo stick facing south, that is, the end of the five twine threads facing the south, so as to continue to record the change of the sun's shadow during the day.

Such a record of the sun shadow is undoubtedly the origin of the staves.

As for the method of determining due south, Ah used the five-stringed pire to observe the sun's shadow to orient the direction.

Thus, this South is relative.

However, there is nothing wrong with this, it is possible to keep track of the time with the daily shadow changes.

As for using the five-gun line instead of the seven-gun, it is precisely because the head and tail of the sun shadow change with the seasons, and in Ah's eyes, the daily changes are too big to refer to.

This is the piano.

After determining the south, the strings on the bamboo piece, as long as it is perpendicular to the southern line, can face the east to record the changes of the sun in a year.

This is Se.

These two astronomical utensils are absolutely high-tech!

In later generations, no one would understand how to use high technology, and people would only play the piano and play.

For this reason, people today seem to have a lot of electronic observation tools, but in fact, they do not know how the earth system operates.

It is conceivable that the ancient Ah, how smart the ancestors of human civilization were, it can be said that the existence of Aha is a miracle of mankind.

With such a high-tech qinse, Ah Ha can observe astronomy with extreme accuracy.

In addition, she will record the astronomical knowledge she has learned.

These astronomical knowledge were engraved on the small bamboo slips opened by the stone knife with a stone knife found nearby, and these bamboo slips were tied with ropes and made into a roll to divide them into order.

The reason why Zhang Jingtao knew this was because Ah Ah stuffed the bamboo slips to him.

However, when he saw the bamboo slip with the word 'Zheng' written by Ah Ah in his surname, Zhang Zhengzhong, he didn't dare to look at it.

This word 'positive', under Ah He's explanation, Zhang Jingtao knows that this is the orthography of the southern method.

However, Ah only roughly said that Dingnan could be fixed, but said the details.

Fortunately, Zhang Jingtao thought about it for a while and understood the mystery of the word 'positive'.

I can't help but sigh, this is the simplified word that can only be created by human civilization!

A simple single word can contain a mysterious astronomical civilization that no one understands today!

Exquisite!

This Dingnan method is also called for this reason: regularity.

It is also the origin of Qu Wenming: Qu Yuan, in the "Lisao" written by this person who has left the clan: the name Yu is called 'regular'.

But Zhang Jingtao didn't dare to think about the word 'positive' in too much detail.

I'm afraid of causing spatial changes.

Even, Zhang Jingtao didn't look at the rest of the words on the bamboo slips.
