Simple, easy-to-understand morality is easy to understand; The morality of truthfulness and uncultivation is easy to publicize.

Ximen Yu, who was born in the aristocracy, explained these two sentences to his father under the nose of Ximen Leopard.

What the father and son are arguing about today, Ximen Leopard and Ximen Yu both know it.

Freezing three feet is not a day's cold.

To this day, when I walked to Ximen Leopard in the study and waited for my son to question myself, this step did not happen overnight.

It's a long process that has to be experienced in the waves of the times.

Twists and turns, and helplessness.

Ximen Yu is not only a nobleman, but also the original gentleman's six arts, the so-called one is five rites, two is six music, three is five shots, four is five royals, five is six books, and six is nine numbers.

These six arts are the "compulsory education" of the ruling class, and only after mastering the six arts can they learn those intrigues, the art of war, and the art of domination.

The Six Arts are good.

Even though Ximen Yan was born as a concubine, his family conditions still gave him enough opportunities to learn the six arts.

Simon may not all be cheap surnames such as Inoue and Murakita, but it is also possible that the son of a nobleman lived in the west gate of the city and used it as his surname.

Ximen Leopard's background is not low, and the fief in the family is enough for the children of the family to receive a good education.

The six arts themselves are also very good, but Ximen Yu doesn't learn much about these six arts.

The art of archery and imperial art is the foundation of the military aristocracy and the samurai class.

Even if Ximen Yan was born as a concubine, such skills also need to be learned, and the family will also provide scholars as masters to teach them the art of archery.

The battle of Lushui seems to be just a struggle between the Mo family and the Yue Kingdom for the hegemony of Sishang, but for the world, some of the influences are far greater than the hegemony of Sishang.

At the beginning of the war, the Yue Kingdom sent warriors to challenge, and several famous warriors of the Yue Kingdom wanted to learn from Xu Bo, Lebo, and Uncle Regent in the Battle of Liangtang, but they were bombarded into a sieve by the volleys of artillery and muskets of the Mo family.

At the beginning of the war, 150 chariots of the elite of the Yue Kingdom attacked the left flank of the righteous division, but half of them were directly wiped out by the salvo of artillery and heavy muskets.

The battle was fierce, and the 500 stirrups of the righteous division raised troops and launched a surprise attack from the flank, which directly defeated the left flank of the Vietnamese army, forcing Yue Wang Phong to adjust his deployment, which indirectly led to the final defeat.

The impact of this great war on those young nobles was huge.

Shooting, in an era when common people could form formations and salvo muskets and artillery, did it make sense?

Even if I am proficient in five shots, can I beat five musketeers alone?

As a child of aristocracy, I learned archery for more than ten years since I was born, and I wore out my fingers I don't know how many times, and in the end, I was faced with five musket-wielding farmers who had been trained for three months.

In the era of stirrups and saddles and dense assault of troops, does it make sense?

As a child of aristocrats, I began to learn to drive, drive, shoot, and hold a car when I was a little older. But all this, which I have spent nearly twenty years learning, has I had any advantage over the stirrups of the peasants?

When the aristocracy cannot be defeated by one against a hundred, the military value of the nobility itself actually ceases to exist.

Coaches, knights, and samurai are actually the same thing.

There is no gunpowder, the people are poor, and the samurai who wear armor and train off production can do it with one enemy and a hundred. Even more, in front of the peasant apprentices who were called up for the Lord, a chariot of the Three Men could break through the defenses of hundreds of men.

But once gunpowder appeared, they could not do it against a hundred, so the king had another choice, so they were no longer the pillar of the king's power, but an obstacle to the king's centralization, because the king could achieve the same or even better effect with cheaper farmers and less money. A three-soldier chariot would never be able to break through the line of three hundred musketeers, and it would not even be able to touch anyone.

When Ximen Yan was thirteen years old, he gave up the study of the art of imperial archery, and some of the above words were the reasons for him when he faced Ximen Leopard's reprimand.

Ximen Leopard asked Ximen Biao, if he didn't learn to shoot the ball, what would he want to learn?

Ximen said that artillery and muskets could crush the royal soldiers, so I wanted to study geometry.

Simon said that muskets can defeat archers, so I want to learn muskets and horsemanship.

Ximen Yan is not a son-in-law, as long as he can learn something, Ximen Leopard is supportive, it is better than shooting a horse and nostalgia for the flowers in the market, and then learn from the time when the Marquis of Jin went out of the city in the middle of the night to have a tryst with his mistress and was assassinated, it is better to learn some horseback riding and muskets.

At that time, the Mo family had many activities in Ye, and some night schools also gathered a lot of people in the market, who began to learn words, and later began to learn some advanced content, such as hook three strands, four strings and five.

As a result, Ximen Yu gave up the study of imperial archery, and instead devoted himself to the Mo family's night school in Yecheng, and began to learn these novelties out of production.

Simon Leopard was in a high position, even if he was incorruptible, but he also had a fief, and spent some money to buy his son a few fine hunting muskets, a set of the best stirrups and saddle bridles.

After such a start, the boundaries of what follows have become somewhat blurred.

Two of the six arts, Ximen Yu directly chose not to learn, but the remaining nine numbers, Sishang is the best.

The study of nine numbers, said: Fangtian, corn, difference, Shaoguang, business merit, average loss, equation, lack of win, and side points.

There are nine in total, including geometry and algebra.

Fangtian refers to the calculation of land area, and the area calculation of plane geometry is the main.

Corn refers to the addition, subtraction, multiplication and division of the calculated transaction amount, which is considered the content of the fifth grade of elementary school in later generations.

Difference, in fact, is decay, and this decay has the same meaning as the decay in the funeral. According to the funeral, the son wears several linen clothes with warp and weft, and arranges them according to the difference or proportional number according to the kinship of the difference. Difference is talking about equal difference series and proportional series.

Shaoguang means that if you know the area of a rectangle or square, the problem of finding the hypotenuse or the length of one side leads to these problems like the open square.

Shanggong means knowing the volume of the cube and calculating the side length of the cube, which is derived from the opening square.

For example, if a village needs eight days away from the battlefield, and another village needs ten days away from the battlefield, then the mean of losing is to let eight households in the village eight days away from the battlefield draw one, and the village ten days away from the battlefield is ten households to draw one, which is an algorithm that uses mathematics to find fairness.

Needless to say, the remaining equation and the surplus are insufficient, and the so-called side is the Pythagorean.

These nine numbers are also one of the six arts, and there are not many people who can learn and be proficient in them, but the Mo family in the world has released cruel words: On the study of nine numbers, it is suitable to be the first in the world.

This cruel word has been released for more than ten years, with the virtue of the Mo family, there is not enough certainty that such cruel words will never be released, and it is just to ask someone to slap the face, and after waiting for more than ten years, no one can shake this sentence.

After shouting for fifteen years, the world has tacitly acquiesced that this sentence is the truth, and when it comes to nine numbers, even those scribes in charge of books in Luoyi have to say: The study of nine numbers is all in Sishang.

Therefore, Ximen Yu said to Ximen Leopard, "I also learned the nine numbers of my father from the Mo family."

Ximen Leopard thought about it, and got it, the study of the nine numbers in the world is headed by the Mo family, and no one shakes it, and this learning of the nine numbers is naturally the best of the Mo family, so he agreed.

Although the paper is not cheap now, it is far more convenient than the previous bamboo slips, and it is also cheaper than the original silk silk, so Simon Leopard asked people to buy paper and pens for his son, so that his son could concentrate on learning something.

At that time, he had a good impression of the Mo family, and the Mo family did have real talent and learning, which no one could deny, so he didn't think much about it at that time.

In his correspondence with Wu Qi, Wu Qi also mentioned that the times have changed, and in the future, the imperial archery warriors may have to be replaced by full-time peasant soldiers.

Three of these six arts have learned the content of the Mo family, and when it came to the six books, Ximen Yu directly said that he would not go to the family studies to learn those six books.

Simon Leopard was a little angry at the time, and said in his heart how to do if he couldn't read, but his son recited a few articles as soon as he opened his mouth, telling Simon Leopard that words are just carriers of knowledge, just like what he wants is the goods on the carriage, but is there any difference between a cart with a horse and a cart with a single horse and a cart with a double wheel?

is the so-called: Zhou Li entered primary school at the age of eight, and Bao taught the country, first with six books.

The name of "primary school" already existed in the Qin and Han dynasties, and the meaning of primary school is the meaning of primary school in later generations, but it may be that it was eight years old to primary school at that time, and two thousand years later it was about six years old to primary school.

What kind of "ancient rhyme" such as enlightenment, when it comes to the age, it is far less than "elementary school", just like the army, division, brigade, company, etc. in the military system, this is retro, and those weird names that sound cool in various dynasties are actually not retro.

In the Spring and Autumn Warring States Period, many people will immediately understand what this means, but it will be difficult for people to understand when they say enlightenment, thinking that it may be a name other than Kyushu.

In the Spring and Autumn Period and the Warring States Period, when it was said that division commanders and company commanders were mentioned, people from all over the world could immediately think that the division commander led about a few thousand people, and the company commander led one or two hundred people, and what kind of title such as a commander sounded like a barbarian.

In the Spring and Autumn Period and the Warring States Period, it was a kind of respect for nobles with the same surname that was closer than friends, and it had long existed, so that the Mo family called each other comrades, and the whole world thought it was so that it was not strange to say such a title.

It is said that Zhou Li entered primary school at the age of eight, and Bao taught Guozi, first with six books.

The six books taught in this primary school are one of the six arts of a gentleman, which is:

One is said to refer to things, and those who refer to things can be seen and recognized, and they can see and see, and the top and bottom are also;

The second is called pictograms, pictographs, painted into their objects, with the body of the body, the sun and the moon are also;

The three are called the shape of the voice, the shape of the voice, in the name of things, take the example of each other, the river is also;

Fourth, it is said that the will, the person who will know, the analogy of friendship, in order to see the finger, Wu Xin is also;

Five said to transfer, transfer, build a class, agree to accept, test the old is also;

Sixth, it is said that the pretend, the pretend, there is no word, according to the voice of the matter, the order is also.

This is the basic structure of Chinese characters for thousands of years.

That is to say, as a qualified nobleman, who is truly proficient in the six arts, in the six books, he must know what it is and why it is true.

The six books teach "how to make words", not just recognize words.

If you take out a character, he can tell you the allusion and origin of the word, whether it is a pictograph, a signifier or a borrowed word?

Why is this word written like that?

What's the point of writing like that?

What kind of philosophy is reflected in it?

It is not to say that you are proficient in the six books, but that you can read and write, which is the minimum requirement.
