Before the advent of paper, the first requirement for compiling a genealogy was that you had to have good physical strength.

Just like Wu, although he is not engaged in labor production, as the only scholar in the entire tribe except for Wang Tian, moving "bricks" every day also makes his upper limb strength not weaker than that of young people.

According to this view, "moving bricks" was first used to describe the scholars, for example, the earliest brick movers of the Tianlong tribe should be the witches of the past dynasties.

There is no need to verify this, because it was not until Wang Tian crossed over that the rest of the Tianlong tribe except Wu enjoyed the fun of moving bricks.

The advent of paper made it possible to improve the information of the registered population and establish a family tree, which Wang Tian had never thought about before.

Even if you think about it, you will be forced to give up automatically by this heavy physical work.

Wang Tian intended to hand over this matter to Wu, who knew everyone in the tribe better than Wu, and he was the natural executor of this work.

As for the format of the genealogy, it is entirely intended to be identified by the method of later fishbone diagrams, and to divide the people of the existing tribes into three age groups: old, middle and young.

At the top of the pyramid are undoubtedly the three old men, Wu and Huo 1 and Huo 2, and in the middle are the adults of the tribe, and this part of the population is divided by families.

In the case of the chief, for example, he has three spouses and five children, so when compiling the genealogy, the chief, as the head of the household and the founder of his branch, is naturally at the top of the pyramid.

Side by side with his name are the names of his three spouses, and below them are the names of their respective children.

Among these children, the boy will have his spouse's name next to him when he reaches adulthood, and when he has a child, he will also be recorded in his spouse's name.

And after the daughters grow up and get married, her name will appear in the husband's family tree at the same time, and so on.

The genealogy of this fishbone map will only show four information: name, gender, relationship with the head of the household, and year of birth and death, which is used to trace back to the source.

Under the name of each founding ancestor, a detailed file is attached to record the life of the individual under this branch.

The time and year of this general table will be uniformly used in the Tianlong era, and the events before the first year of Tianlong will be calculated by Wu forward.

For example, the information of the leader will be recorded with the following information: Wang Tianying, born 25 years before Tianlong, served as the leader of the tribe 6 years before Tianlong, and led the tribe in the autumn of the first year of Tianlong to make bricks and burn stones to build a wall to ensure the safety of a clan.

The surname Wang is naturally designated by Wang Tian's privilege, and he can't be an outlier! In fact, he has no half-dime blood relationship with this tribe.

The word heaven in the middle represents the generation, and Wang Tian intends to start the starting generation of the tribe from Xuan, heaven, earth, and people.

The three old men of Wu and Huo Yihuo are the Xuanzi generation, and all the adults of the current tribe are the heavenly generations, and the sunspots and Xiaoling are the third generation of the earth characters.

The next fourth generation is the human character generation, and those who are born after it are arranged in order according to the thousand-character text "Heaven and earth are yellow, the universe is desolate...".

Xuan means the beginning, for the beginning of the meaning, heaven and earth for the three talents, take a complete auspicious meaning, the yellow character through the emperor, will be used as a special honor, used to add to the name of the person who has made outstanding contributions to the tribe, to show the highlight.

For example, Kuroko is famous for his meritorious work in firing pottery, and in order to commemorate his merits, later generations will not only record it in the family tree, but this glory will also be reflected in the name Wang Dihei.

Then Kuroko will not only have the strange official name of Wang Di Hei, but will also have the honorific title of "Black Emperor (Yellow)".

With a surname, you can distinguish different tribes, and you can avoid the occurrence of close relatives from marriage.

With the generation, the relationship with each member of the tribe can be directly seen from the name, and the distinction between the elder and the young can be clearly distinguished.

Interestingly, when it came to Wang Tian's generational division, Wu even wanted to list him in the Xuanzi generation, and this Wang Tian resolutely disagreed.

Brother is still a cute little princess, even according to his real age, it should also be a heavenly generation, not to mention that there is a heavenly character in his name.

Wang Tian insisted on being classified in the Tianzi generation, in addition to the above reasons, there is also a layer of respect for the three Xuanzi elders.

To work out a genealogy, first of all, there must be a unified script, and Cangjie, who created the script, does not know where it is, and this work can only be undertaken by Wang Tian.

From more than 90,000 Chinese characters, Wang Tian will first select about 3,000 commonly used Chinese characters for compilation.

In the early stage, Chinese characters would mainly be closely related to tribal life, and Wang Tian planned to adopt a dual-track parallel method of pictographic ideograms and Chinese Simplified Chinese forms.

At the same time, two sets of scripts were created, the hieroglyphs were mainly used for the daily life of ordinary people, supplemented by Chinese Simplified, for professionals such as Wu and children who could accept it.

The reason why it is so troublesome is because Wang Tian believes that there is no soul without inheritance, and the breadth and profundity of Chinese characters cannot be in his own hands, which has changed his historical trajectory.

The Chinese Simplified Chinese character that pops out of thin air seems bald in any case, even if it has a certain degree of advancement.

Chinese Simplified Chinese was listed by Wang Tian, and the corresponding hieroglyphs, several alternative plans were proposed by many people, and the method of democratic voting was still adopted, and it was finally determined.

Hieroglyphs close to life are more conducive to the understanding of the people in the primitive era, and Chinese Simplified Chinese will eventually be accepted by the general public through the inheritance of generations.

The two great gods happily decided on the way of writing that would have a profound impact on later generations.

For weaving, there is now a bunch of plant fibers, and if you want to weave cloth, you can't just have a loom.

Cloth is made of thread or yarn, and if you want to make cloth, you must first get yarn. A bunch of plant fibers that have just been extracted, that is not called yarn, it is a mess.

The process of twisting the loose messy fibers into lines and pulling them into yarn is called spinning, and the earliest tool used for spinning in China is spinning.

The structure of the spindle looks very simple, Wang Tian saw others use it in the countryside when he was a child, although it is simple, but its working principle is very scientific:

It skillfully uses the weight of the object itself and the force generated when it rotates to make the messy fibers drawn and twisted into yarn.

The outer diameter and thickness of the spindle are the key to determine the fineness of the yarn, the outer diameter and weight are larger, the moment of inertia is also larger, and the spun yarn is thicker.

The outer diameter is moderate, the weight is small, the thickness is thinner, the moment of inertia is small, but the rotational continuation time is longer, so the yarn is finer and more uniform.

In the impression of many people, the tool for returning to the line is the rows of rotating hand-spinning wheels in Nanniwan in the movie, rotating like electric fans.

In fact, just a spindle can extract the thread from the mess by using its own gravitational inertia. The spinning wheel simply provides a constant power for the spindle.

The main mechanism of the spinning wheel: spindle, rope wheel and handle. The mechanical principle is very simple, the common hand spinning wheel is the spindle on the left, the rope wheel and handle on the right, and the middle is driven by a rope string called horizontal.

In movies, it's generally like this, he only needs to go alone, and he can complete the operation.

Another hand-spinning wheel is to install the spindle on the rope wheel, which is also driven by rope strings and called vertical. The vertical type requires two people to cooperate at the same time.

Because the horizontal spinning wheel only needs one person to operate, it is more suitable for the rural sideline of a family, so it has been passed down to later generations.

After that, there were pedal spinning wheels and large water-wheel driven spinning machines, which greatly improved the efficiency of spinning.

It is not difficult for Wang Tian, a person who studies mechanical design, to make these machines, but at this stage, there is no need at all.

The various materials and parts needed to make hand-spinning wheels and textile machines have been made by the second brother and Liu Bei.

Wang Tian only needs to assemble them to turn them into spinning wheels and looms.

All kinds of parts produced in a standardized way, the specifications and sizes are universal, and any one of the same parts can be replaced on any machine at will.
