The stone looked a little lost, standing there looking at the growth rings on the tree, feeling unwilling.

Han Cheng quietly wiped the sweat from his head.

It's really crazy!

As a modern person, I feel ashamed of myself.

After calming down a little from this emotion, Han Cheng began to think about what Shi Tou was struggling with.

Before the advent of the calendar, there was really no way of knowing things like date of birth.

However, the Qingque tribe now has the most basic calendar. Children born after the calendar is established will have birthdays and know how many years they have lived in this world.

Thinking about this, Han Cheng suddenly remembered the tribe's method of using height to determine whether a person is an adult.

This approach is unfair.

Some people grow fast, some grow slowly, some are tall, some are short. The biggest result of this is that those who are tall and younger in actual age are already adults, while those who grow slowly and are short are still classified as minors.

Human growth is not only physical, but also psychological.

It seems that the standard of adulthood in the tribe needs to be changed. Height can no longer be used as the standard. The best way is to use age.

Now that the tribe has a calendar, this can be achieved.

However, Han Cheng was a little confused about what age was considered an adult.

According to his inherent thinking, it would be best to set the age of adulthood at 18.

But this is a bit unrealistic.

Due to reasons such as medical care, food, and working methods, primitive people did not live long compared to people in later generations.

It’s not that they can’t live to a ripe old age, but that conditions don’t allow it.

The unnatural death rate is really too high, reaching over 90 percent.

It would not be possible to set the age at 18 at this time. The Qingque tribe is still better off today. If it were other tribes, according to this standard, more than half of the people would have died before they had the chance to pass on their family line.

Moreover, the time of adulthood is set too late, which is not conducive to the development and growth of the current tribe.

First, the working time will be shortened, and second, the next generation will appear too late.

Fourteen or fifteen years old should be about the same...

This is just his preliminary idea now. The specific age considered as adulthood will depend on the actual situation of the Qingque tribe.

But these are things that can only be implemented after several years.

After all, there are still many minors in the Qingque tribe. They are like stones. They were born before the calendar came out and don’t know the exact year and month of their birth.

Therefore, the Qingque tribe will need to continue to implement the practice of determining adulthood based on height for a few more years.

But before that, we can come up with some other things about calculating age.

"Shitou, come here..."

Han Cheng called out to Shi Tou, who was squatting in front of the tree stump and was unwilling to leave after his idea was rejected by him.

Shitou stood up, walked to Han Cheng and listened to what Han Cheng said.

He was confused at first, but after listening for a while, a look of enlightenment appeared on his face.

Finally became excited.

The method Han Cheng told him was the twelve zodiac signs.

Each year is named after an animal.

For Han Cheng, who came from later generations, the twelve zodiac signs have a deep sense of familiarity.

Twelve years is a cycle. As long as you know your zodiac sign, you can quickly calculate your age and easily compare who is older and who is younger...

The stone that created the calendar under Han Cheng's guidance quickly accepted the idea that a cycle is twelve years. After all, a year consists of twelve months.

"The first year is called the Year of the Sparrow."

After understanding Han Cheng's meaning, Shitou shouted happily.

Han Cheng's face froze and he couldn't help sniffing.

Before he even started saying "one rat, two oxen, three tigers, four rabbits", he had already been led off track.

However, it is necessary to make some changes to the twelve zodiac signs, because some of the animals in it have never been seen by the people of the Qingque tribe.

Not to mention the rest, just the dragon, Han Cheng found it difficult to explain to them.

After much deliberation, I decided to make changes based on the actual situation of the Qingque tribe.

This matter is not his one-man show, but the result of collective wisdom. In this way, the things produced by everyone together will be more familiar to everyone and easier to accept.

After the news of naming the twelve years with twelve kinds of animals and using them to calculate age spread, many people in the Qingque tribe became very interested and wanted to express their opinions on this matter.

Among the twelve zodiac animals, the sparrow has the highest popularity because their totem is the blue sparrow.

The vast majority of people believe that it is natural for the totem of the incarnation of the god to be the first of the twelve zodiac signs.

The first of the twelve zodiac signs was thus determined.

As for the second zodiac sign, everyone was discussing it. Some said it should be the deer, because there was a large group of deer in their tribe, and deer were not only edible, but also could help with work.

There are also people talking about fish.

The reason is that when they were in the most difficult times, it was the Son of God who saved the entire tribe with fish, and from then on, fish became their staple food. It was because of the fish that their tribe was able to develop greatly.

And the one about rabbits...

Eventually, the supporters of the fish prevailed, and the fish became the second zodiac sign, with the deer being the third.

The fourth zodiac sign has not changed, it is still the rabbit...

After some discussion, the twelve zodiac signs were finally decided.

One sparrow, two fish, three deer, four rabbits, five dogs, six chickens, seven sheep, eight cows, nine tigers, ten snakes, eleven loaches, and twelve pigs.

Except for the cow, the other animals that serve as zodiac signs are all encountered by the tribesmen.

The cow is an exception. Although the people in the tribe have never seen it, they are not unfamiliar with it because of the legend of the Cowherd and the Weaver Girl.

Therefore, when determining the zodiac, the ox was also added.

Han Cheng's face twitched several times as he looked at the twelve zodiac animals whose appearances had changed drastically.

The arrangement of the zodiac signs still starts from the first year of Qingque.

Now is the fourth year of Qingque, which corresponds to the Year of the Rabbit.

At the beginning, many people did not understand why the same year had two names, and thought it was best for a year to have only one name.

Han Cheng spent a lot of effort to make them understand.

The example given is the eldest brother.

The eldest brother is the leader, which means one person has two titles, just like Nian.

"You are a sparrow."

"You are also a sparrow."

"You are a fish..."

In the tribe, everyone used this new zodiac sign to identify the children born in the first year of Qingque or later.

"I want to be born in the year of the Ox!"

This is the cry of the envious stone.

"I want fish!"

"I am a tiger..."

People who want to have their own zodiac sign began to choose it by themselves happily.

Han Cheng's face twitched again. How could you play like this?
