As an engineering dog who likes to be lazy, Lao Zhang used ABCD to do pinyin in the lecture hall purely for his own convenience. Pen? Interesting? Pavilion wWw. ｂiquge。 Of course, in fact, the tone of Luoxia's voice is very different from that of more than a thousand years later, but this does not prevent Lao Zhang from continuing to be lazy, but with Old Man Cao, this laziness does not need to steal.

Cao Xian's "The First Book of Music Training" was printed by Lao Zhang in the spring of the tenth year of Zhenguan. It didn't use any movable type printing, it wasn't tall at all. The efficiency of movable type printing is not as good as that of engraving printing, at least in the Tang Dynasty, it is certainly far inferior to engraving printing.

The reason why engraving is easy to make mistakes is because of management problems, as long as you are willing to reward and severely punish, the fault tolerance rate can be infinitely close to zero.

That's right, it's that simple.

However, the pinyin textbook for bear children obviously can't only have an alphabet, but also a vivid picture or something.

At this time, Zhang De finally sacrificed the stone printing technique that he had been trying for more than two years but finally succeeded. This is a long-term job that can be used in the space age, and it should not be eliminated in 2,000 years.

The picture uses a lot of life-like things, such as "ah", that is, a bear child opens his mouth wide and stares at the distant mountains and clear sky, and his two hands are trumpet-shaped.

The person who painted the painting was Zhang De himself, and then according to the principle of oil-water separation, he applied a layer of wax and then began to print. The effect is very good, basically can meet the printing of newspapers, posters, posters, big-character posters, leaflets, etc.

In order to make it easier to flip through, Zhang De also made a binding machine, which positioned and punched holes in the printed products, and then sewed them with cotton and linen threads.

A textbook for enlightenment before the age of seven was born.

In order to clarify the copyright, Zhang De also specially printed a "Cao Fuzi Descending the Mountain" on the cover, which is Cao Xianxian's wind and longevity eyebrows and long beard, and then rode a tricycle down the mountain happily.

Zhang De believes that after a thousand years, this famous painting will definitely fetch a good price.

"The local pronunciation of Chudi is very strong, and try it first."

Cao Xian is also a truth-seeking old pedant, and at the same time he never shy away from his mistakes, and Cao Fuzi never took face to heart.

Because it is an enlightened textbook, it includes the "Thousand Character Text", and the content should be after the alphabet, and it is all phonetic version. It also includes a few first-class poems that have been passed down for centuries, and when these Chu children arrive in Luoyang and Chang'an in the future, they must also let the people of the capital know what it means to be "only Chu is talented".

In the summer, there were several heavy rainstorms, and Zhang De wrote a note to Duan Lun saying that there might be places where the embankment would burst in this rhythm, either Jingchu or Jingchu hundreds of miles down.

When the Ministry of Industry Shangshu saw that the note was written with a double-flower red stick under his hand, his face suddenly changed greatly, and he first went to find Xuanling, the left servant of the Shangshu Sitting Hall, and said that because I sent Zhang Caozhi to act in charge of water affairs last year, it is no problem now. But Jiangzhou is not easy to say, there is a big lake there, and it will be bad if you don't get into the estuary.

Fang Xuanling took a look at it and said that this is easy to do, isn't the prince still back, and see the old man put a burden on the prince's shoulders.

When Duan Lun heard this, he hurriedly slipped away, this old house is simply a pit.

So the outer court suddenly made a fuss, and the inner court was also as bad as a dead father, and the emperor was not good. I always feel that why did the stage suddenly appear for the prince to perform?

And the warm man Li Chengqian, this scene also asked Ma Zhou, who came to take care of mundane things: "King Bin, is Da Lang okay in Chuzhou?" ”

Ma Zhouxin said that his mother is mentally retarded, and at this time he still has the heart to pay attention to Zhang Caozhi, as the prince, are you okay to have a snack? Are you okay? If you're well, it's better if it's sunny!

For Fang Tianwang, who made trouble, the important ministers were also wondering, saying that this was the bait thrown by the boss or was Fang Tianwang making his own opinion? Theoretically speaking, it is very reasonable and scientific for a prime minister to add a burden to the prince. After all, there was also an interaction between Yang Su and Yang Guang in the previous dynasty, as for Gao Ying...... Don't worry about these details.

However, Zhenguan celebrities are all human spirits, and there are very few mentally retarded, so everyone invariably pondered: Could it be that Li Dong is going to fish for law enforcement again?

Last year, the prince toured the east, and the emperor directly forgot about Li Chengqian, and he did not issue an edict to return to the court.

However, when the majority of important ministers said that this prince was really not good, the warm male prince was still concerned about whether Zhang De would drown in the summer flood.

It's a gentleman and a minister, as it should be.

Ma Zhou was also tired, but fortunately, because of the engineering dog, ginseng in Liaodong began to be used on a large scale. Although the masses of people do not know what the use of ginseng essence is, ginseng tablets in the mouth can refresh the mind and become a must-have item for celebrities to stay up late and work.

If there is a need for continuous night battles in the army, the elite soldiers are also one piece per person, which is more powerful than two catties of old white cadres.

So Ma Zhou tried to sort out the next things for Li Chengqian while holding the ginseng slices, anyway, if Li Chengqian was finished, he wouldn't think about it. In any case, Li Tai, a fat man, can't be allowed to take the position, as for Li Shimin...... He's the boss, he's the best!

Ma Zhou, who worked diligently, traveled thousands of miles from Chang'an to Huainan, and Ma Zhou, who was originally holding a piece of ginseng, instantly felt that he was not holding a piece of ginseng, but a large eagle because of Li Nuannan's kindness......

The prince decided to promote the "First Book of Music Training" in Huainan Province!

When he knew this, Ma Zhou almost fainted. Is this something you can do? Everyone else can do it, but you can't do it! Don't you know that your dad doesn't like you to make trouble?

Ma Zhou, who was spitting saliva, almost wanted to press Li Chengqian to the ground and rub it vigorously, and the local chief officials could not promote this matter through their own authority, but through their own prestige. Nominally, these "folk textbooks" are illegal, and they can only be "initiated" by local "village sages".

It's not impossible to do it, for example, if you are Chang'an Ling, you are in Chang'an, that's no problem, anyway, go out and turn right and go north is the emperor's house. Or if you are an official in Anping or Wucheng, you can also do it, because the surname of that place is actually Cui. Or you can do it in Huaiyuan in Hetao, because there are a bunch of illiterate barbarians in that place, and the "Analects" they learn is completely different from the style of painting in the Central Plains.

However, Huainan is a place of ointment, and the wealthy families are relatively weak, and the emperor intends to do it as a reserved land. You are a prince, playing cards with the real emperor, you come up and take a "Nine Treasure Lotus Lamp", you don't call it a share of worries and responsibilities for the king, you call everyone to die together!

Ma Zhou's side staged "with a big long stem", and it was not easy to have a good time in Chuzhou, and the ninety-five-year-old Cao Xian scolded "spicy block mother" for the first time. This made Lao Zhang very happy, at least Old Man Cao still looked like a human, not an immortal.

"You had a holiday with the prince?"

Cao Xian squinted at Zhang De.

"No, I have a good relationship with the prince, and I saved him once, and that time he almost fell off his horse."

"Then why did the prince harm you?"

“……”

I'm also helpless, I'm desperate!

"The prince also does bad things with good intentions."

Lao Zhang looked at Cao Xian stupidly, "Senior, I really don't hide it, this prince really has no master's appearance, and he is too generous and lax." When it comes to playing, it's a bit of a drill. ”

"Is it really good for you to criticize the prince like this?"

"I really have a good relationship with the prince."

Cao Xian stared at Zhang De for a long time, "Stay away from Li Shan in the future." ”

“……”

Wait, what kind of eyes are you looking at? What kind of eyes are you?!
