On the Baqiao, Concubine Yang supported Li Ke, held Li Ke's hand, and cried darkly.

In this situation, the separation is imminent, and Li Ke can't help crying.

Seeing that the mother concubine was so sad, Li Ke couldn't help but comfort: "Mother, the child is just going to Qizhou, which is very close to Chang'an. If you miss your child, she can come back to see you at any time. ”

Concubine Yang took Li Ke's hand and carefully advised: "Ke'er, when you go out, you must take care of yourself, don't freeze and starve, don't get sick!" When you are free, remember to write a letter to your mother to report safety! ”

Li Ke nodded again and again, and then said to Li Su: "Sixth brother, my brother is leaving, you must take care of your mother!" By the way, the separation is imminent, the sixth brother is very talented, so write a poem for the elder brother! ”

Li Su couldn't help but have red circles in his eyes, pondered for a long time, and then groaned: "Thousands of miles of yellow clouds and daylight, the north wind blows geese - rain." Don't worry about the road ahead without knowing yourself, who in the world doesn't know you? ”

And Shangguan Yi, who was following beside him, heard the poems of King Liang, His Royal Highness the King of Shu, and couldn't help but feel excited in his heart.

Don't worry about the road ahead without knowing yourself, who in the world doesn't know you?

These two sentences will surely become a swan song for the ages!

Well, if the poem is flawed, it is not without it.

You are like the first two sentences of thousands of miles of yellow clouds and daylight, and the north wind blows geese and rains, which is not quite the same as the current scene.

Now the sky is full of clouds, and it is not raining.

But when a poet writes poetry, a poet's business, who can demand that it must be realistic?

Years from now, who will remember that time?

Even Shangguanyi felt that if the rain in the second sentence was changed to the word snow, and the north wind blew geese and snow, it seemed that the effect would be better.

As for the fact that it is still summer, it is impossible to snow at all, Shangguan Yi feels extremely regretful.

And Li Ke, the king of Qi, couldn't help but feel a sense of pride in his heart after hearing his brother's farewell poem.

Li Ke gently broke free of Concubine Yang's hand, turned over on the horse, and said with a long laugh: "Mother Concubine, sixth brother, go back!" I'm gone, you guys, take care! ”

"Thousands of miles of yellow clouds and daylight, the north wind blows geese and rain. Don't worry about the road ahead without knowing yourself, who in the world doesn't know you? ”

Li Ke, the king of Qi, rode forward, caught up with the entourage in front, and they began to hit the road.

And in the air, the groaning of King Qi still came from the air.

……

Under the emperor's order, one-third of the officials of the household department would come to the primary school every day to listen to classes.

However, now the teacher in the primary school is no longer Wang Xiaotong, but has been replaced by Li Su, the king of Shu.

It turned out that when Wang Xiaotong heard that Li Su, the king of Shu, applied mathematics to the flood, his heart was suddenly touched.

Wang Xiaotong suddenly felt that in fact, arithmetic should not only stay on paper, but should be applied to real life.

The reason why arithmetic is so unvalued and has such a low status is because mathematics is useless.

If mathematics can show amazing value in reality, mathematics can definitely be popularized quickly.

And because of this touch, Wang Xiaotong decided to join in the practice.

Therefore, Wang Xiaotong did not hesitate to resign from his position as a master and began to study behind closed doors.

In fact, Wang Xiaotong's research, which also existed in later generations, was applied mathematics.

Applied mathematics is a discipline that applies mathematics to reality, and it plays a great role.

Wang Xiaotong wanted to study applied mathematics, and Li Su naturally supported it.

Li Su also specially selected some of the textbooks of later generations for Wang Xiaotong to study.

However, after Wang Xiaotong left, it was difficult to find a suitable master for a while.

In particular, new arithmetic needs to be taught.

In the end, it can only be to let Li Su go up.

Fortunately, this is not the first time Li Su has been a gentleman.

Last time, I gave a lesson to Kong Yingda's old gentlemen.

This time, the target of the class was changed to an official from the household department.

For Li Su, there is no pressure at all.

In the first class, because Tobe Lu Shilang didn't answer a question correctly, Li Su unceremoniously slapped his palm.

Lu Shilang felt that Li Su was targeting him.

Well, the gambling contract for calculating the account book of the household department at that time was proposed by him, and it was understandable for Li Su to target him.

It's just that even if Li Su really targeted him, he didn't dare to complain.

At the beginning, Li Su even hit Kong Yingda's palm.

Even Kong Yingda is helpless, let alone him?

And those students in the elementary school are even more energetic at this time.

It turns out that these household officials are nothing more than that!

In terms of account calculation, they were beaten.

Now in learning new arithmetic, they have been thrown away more than one street away.

Now they are a little disdainful of these household officials......

And their enthusiasm for new arithmetic suddenly came up.

It turns out that the new arithmetic is so good?

Can you directly beat the knowledge of household officials, can you not be bullish?

As a result, students are more motivated to learn.

Even Cheng Chuliang, who usually dislikes to study the most, is full of energy at this time and is dedicated to learning new arithmetic.

……

At this time, the people of the family were getting together to discuss the matter of jointly organizing a lottery.

Although, with the strength of several of them, it is not a problem for each one to be held separately.

But this piece of the cake is just too big.

So big that it is impossible for each of them to swallow it alone.

Whichever of them is held alone, it will inevitably provoke attacks from the others.

And if they join forces to hold it, I believe it will be able to be quickly promoted throughout Datang.

And these families have already inquired, and Li Shimin did not plan to discuss this matter in the court.

Because Li Shimin knows very well that this matter is absolutely impossible to pass above the court.

Since Li Shimin doesn't do it, then what's the matter if the people of their family do it?

I heard that last time, in just three days, King Liang sold nearly 10 million lottery tickets.

In this, their family has contributed nearly one million contributions.

These were all smashed out after they were recognized as fraudulent in their exchange for the second prize.

They don't want to win the odds, they mainly want to get a QR code printed on a winning number.

They want to see what exactly this QR code is and whether they can copy it.

And with nearly a million lottery tickets, they can only win a fourth prize at the highest.

This makes the people of the family feel that the grand prize has probably been hidden by King Liang in advance.

However, it turns out that on the fourth and fifth prizes, there are printed QR codes.

The fourth and fifth prizes they won were not taken to claim the prizes, but they were all taken back and studied carefully.

However, in the end, I couldn't figure out what this QR code is.
