Lu Hanyang stood in front of the quiet room in the apse of the Eight Views Palace, and Li Er stood beside him. There was no one else, not even the samurai wok, who could only wait outside the three zhang.

"After these small letters, numbers, is a door of university questioning, in the desolate land, before the age of seven children just cultivate their nature, let them maintain their innocence, under the guidance of special kindergarten teachers, let them establish a correct outlook on life." Lu Hanyang said.

"The same is what the land teaches to children?" Li Er didn't expect that what Lu Hanyang handed over to Li Lizhi was the knowledge from the desolate land.

"Where are there no children? Children are the future of a nation, and the main body of the desolate land is still just ordinary people, and only a very small number of them can really obtain immortal fate. Lu Hanyang said.

"This pinyin, after learning, can make children's literacy become very convenient, even if they don't know at all, as long as the pinyin is marked, then it can be accurately recognized.

Of course, the meaning may require more accumulation to be discerned. And that's a huge step forward, isn't it?

And not to mention numbers, now your Li Tang's calculation method is too backward, although there are some superb arithmetic masters, but their knowledge is passed down from generation to generation, and the broom is self-cherishing.

In this way, the inheritance of the broom from generation to generation has not only not been carried forward, but gradually declined. Not many people have been able to figure out Zu Chongzhi's "Fixation" so far, right? That's the consequence. Lu Hanyang was a little helpless.

Self-cherishing is a weakness in human nature, and even if there are some people who are very open-minded and honest about everything, there are many more who are conservative. They value their stunts more than anything else, and they have to pass them on to the next generation only when they go into the coffin.

But how can the moment of dying convey the complete virtuosity? Therefore, what future generations get is only a part of it, so that it will be passed on from generation to generation, and finally it will be completely extinct.

"Numbers, it looks simple, one might even say rudimentary. However, it represents the most basic foundation of arithmetic, and this seat is not specialized in mathematics, but with the foundation, it will be more convenient to study in the future than before. Lu Hanyang handed Li Er a textbook of elementary school mathematics.

This was formulated by Li Chunfeng according to Lu Hanyang's requirements, and addition and subtraction were the mainstay, but Lu Hanyang handed Li Er a multiplication formula table at the end of the book.

Li Er looked at it, and the explanation was very simple, and he quickly understood the wonderful use of these numbers. It is much easier to add or subtract numbers than in Chinese.

And the last multiplication formula, Li Er is even more astonishing, because this formula is not only multiplied between one and nine, but can be used in a deeper and broader area, multiplication and division with numbers, and it is convenient to see at a glance.

"The use of numbers, coupled with this multiplication formula, will greatly change the operation of various resources in Datang, and the operation work of various states and counties may be directly reduced by half." Li Er immediately added this digital operation to the governance of the world.

"How? Isn't it very convenient, and more accurate. This has a transformative effect on all walks of life in the world. Lu Hanyang boasted.

These have been tested by the Great Celestial Empire in later generations, of course, the Arabic numerals do not know when they were made, but pinyin is indeed the masterpiece of countless educators of the Great Celestial Empire.

Such things are more advanced than the Tang Dynasty. So of course Lu Hanyang will surprise Li Er when he takes it out, and he does have the ability to change the world.

"Immortal Chang, pinyin, the numbers are indeed very subtle, but what are these little symbols?" Li Er flipped through the math textbook, and was not only surprised by the numbers, but also some of the small symbols in it that caught his attention.

As you can see, these symbols are something that helps people understand the meaning of the words. This is called a comma, which means that a sentence is not finished, and there is a follow-up. This is a full stop, which means that a sentence is finished. There are also colons, semicolons, exclamation marks, ellipses, dashes, quotation marks, and more. Lu Hanyang said.

"This ...... Indeed, with these symbols, the meaning of a sentence is clearer. Li Er had to admit it.

"Emperor, there is no interval in a passage now, just a large paragraph of text is placed together, how can you tell the meaning? There are many meanings conveyed in one sentence, and many times it can be misinterpreted into another meaning. Lu Hanyang said.

"This, Xiao Ke is willing to listen to it." Li Er said.

"For example, what does it mean that 'the people can make it from it, but not from it'?" Lu Hanyang asked.

"The people can make them live freely, but they can't let them understand too much, this is the instruction of the ancient sages." Li Er replied.

This is the Confucian interpretation, right? They have been implementing the policy of fooling the people for so many years and have won the support of the imperial power? Absurd! Lu Hanyang was dismissive.

"Does the Immortal Chief have other opinions?" Li Er was surprised.

"If this is really the case, then Confucius would not have taught without class in the first place, with three thousand disciples and seventy-two sages, which is highly respected by Confucianism, and such a person would say such a thing?" Lu Hanyang said.

"This sentence should be understood as 'The people can do it?' No, let it be known! Can the people let them wander freely? No, we should teach them so that they can understand things and know shame. This is the kind of teaching without class. How many people have Confucianism poisoned for so many years! Lu Hanyang said.

"This ......" Li Er's understanding of this sentence can be said to be deep-rooted, he is a person with vested interests, of course he believes in the previous explanation, after all, it will help his rule.

"Why, are you afraid that the people will understand the methods of your people? There are no fools in this world, but they are not as knowledgeable as they are, and thus misled by the strategies of fools.

The price to be paid for opening up the wisdom of the people is that these sensible people will understand how the family and the royal family rule them. It's hard to be toyed with by you, so it's understandable that you don't want to accept it. The corners of Lu Hanyang's mouth twitched, and he said disdainfully.

Defending their own interests is a common problem for those who stand in the ruling class, after all, no one wants anyone to come out and challenge their rule. But can't this really change? No, but the rulers have no confidence in their rule.

Because he didn't dare to put his chips on the small possibility that the people knew too much and would not rebel against him later.

"The country is rich and the people are strong, everyone has enough food and clothing, and the four Yi come to the court. In such a country, will anyone be willing to rebel? The country has the strongest military power, and the people live a happy life, and whoever wants to rebel will not agree to the people. Lu Hanyang said.

A rebellion without the people is a rebellion. The people can't survive anymore, and they get involved, and that's called an uprising.
