There was no class, so the children ran out to play after dinner.
Some went to the toy room, and some strolled around Zhuangzi. They found everything interesting.
The children in Chang 'an were asking their parents to buy things for them.
Rubik's cube was called a nine-palace block in the Tang dynasty.
Last night, he bought it for 20 copper coins each. No one could get it for free, and it cost 100 copper coins.
Today, it was on sale. All the stalls that sold roasted oysters were selling it.
It cost 6 copper coins each. These retail stalls sold it for 52 copper coins for 10.
They could earn 0.8 copper coins each. The price in Chang 'an was the same. It couldn't be too high, but it could be too low.
Some sold it directly, while others gave customers one for free no matter how many roasted oysters they bought.
As for the big restaurants, they would give one for every meal.
Li Chengqi was busy renting a shop. He negotiated the price and decided to rent it for a year.
If the Tang dynasty had a bad year in the coming year, he was not allowed to raise the price. If the year was good, the price could not exceed 10% at most.
These rented shops sold things made by craftsmen. Every item was marked with the craftsman's number and name.
If a craftsman made the same item with a high maintenance rate, the craftsman would either reduce his remuneration or leave the alliance.
Similarly, the rented shops helped to repair some utensils.
The utensils with warranty were repaired for free, provided that they could not be damaged by people.
Li Chengqi thought this was a good idea. In the future, everyone would be willing to come to his alliance to buy things.
Moreover, the shops were there. They could not run away.
Sure enough, after the children bought the nine-palace block, they did not run out of the city. They usually competed with their friends in the shops.
Of course, the children of more families still had to help make mud in exchange for money and pottery.
Not only the children played, but also the adults played.
Everyone felt that they could turn the nine-palace block back into six faces. The dawn was in front of them, and they were just a little bit away.
The ordinary people did not mind. If they could not come back, they could play slowly. It was also interesting to meet one face.
The Imperial College in the palace was in trouble.
Li Yi had said that it was a problem of mathematics.
The Imperial College had mathematics, which included two professors and one teaching assistant.
The books they studied included "Island", "Five Classics Calculation", "Fixed Numbers", "Third Grade Calculation", and so on.
Since it was a mathematical problem, he tossed the Rubik's Cube to them. One for each student. The Imperial Court paid for the Rubik's Cube and transferred it back to the Rubik's Cube.
If it were Li Yi, he would kneel down.
He only knew the Six-Step Restoration Method. As for the formulas, he just had to memorize them. The more he practiced, the more proficient he would become.
If the third-order Rubik's cube was turned back grid by grid according to the calculation method, then the calculation of the change rule …
The people from the Imperial College were confused, not just those from the Mathematics School.
If you feel that you should be better than calculus in other subjects, let's do it. Let's not calculate. Let's just switch back to the six facets.
"I don't want to play anymore. It's so annoying." Empress Wang threw a Rubik's Cube aside. Her head was hurting.
The other palace maids and eunuchs were relieved and put away the Rubik's Cube in their hands. In order to cooperate with the Empress, they were all working hard.
Li Longji was smarter. He didn't touch it at all. Instead, he was reading the letter below.
A Rubik's cube with all six sides aligned was placed on the table. It looked quite beautiful.
He saw that the state capital had mentioned the matter of running a school. It was difficult to run an official school.
The things taught by the capable local clans were different from what the local officials learned.
The local officials' learning was now called Confucian Classics and Medicine.
Medicine was naturally the study of medicine. The Tang dynasty attached great importance to it. That was why Li Longji valued the medical books written by Li Yi.
The medical books written by Li Yi were compared by the people of the Imperial Medical Department with the current medical books. They found that Li Yi's writing was more complete.
The Confucian Classics now followed the Five Classics, plus the Classics of Filial Piety and the Analects of Confucius.
Li Longji didn't know that in the future, in order to fight against the Confucian school, he opened a Confucian school in the local officials' learning.
Confucian school was a Taoist school. It targeted Buddhism and Confucianism to form a tripartite balance.
At that time in the future, he worked very hard and found a problem. He wanted to change it.
Unfortunately, due to the limitations of his education since he was young, Confucian school couldn't save the Tang dynasty.
Then, there was the An Lushan Rebellion. Later, the emperor even took out the "Legend of Gongyang" to teach.
It paid attention to unity, class classification, and ideology.
At the same time, it called on scholars to not forget the national hatred. There was a very classic sentence in it: Can nine generations take revenge? Although it can be a hundred generations.
Li Longji couldn't see the future. What he was worried about now was that the family taught their children to put the interests of the family first and the country second. Only with a family can there be a country.
"Why do we change this? The local families have their own schools. We can't act rashly. "Li Longji held the pen and didn't write.
Some of the local officials' schools required the family schools to be merged with the official schools. This meant that the family schools would be abolished and all the children would be in the official schools.
The local officials understood that in the long run, the country would no longer be a country.
"Sigh!" Li Longji sighed. He put this aside and did not approve it.
He knew that he couldn't deal with the Under Heaven family. Previously, the Imperial Guards were in the hands of his brothers.
The local military power was naturally in the hands of the children of the other families.
Even the generals who didn't have families in the beginning would be given benefits, women, and …
"It would be good if they were all like Brother Yi. He taught people to be loyal to the emperor first and then to love the country. He helped to build my private army, the Winged Knights, and taught them personally."
The more there was a comparison, the more Li Longji missed Li Yi.
As for some people comparing Li Yi to Wang Mang, Li Longji didn't agree.
Wang Mang also had a family. He didn't abandon his family and teach others to be loyal to the emperor. If not, how could he usurp the throne?
From the looks of it, Li Yi didn't even think about being the emperor.
"Gao Lishi, take a look and approve the unimportant ones." Li Longji put down the pen and his thoughts drifted to Zhuangzi.
Gao Lishi had already taken a look, but he didn't say anything. He took it and sat at the side to approve.
Don't look at how he accepted bribes. He didn't show any favoritism when writing memorials.
Li Longji wanted to find Wu Jieyu, the future Wu Huifei.
Wu Huifei was beautiful and sensible. She could always make people happy.
Li Longji walked and walked until he saw Empress Wang. Ah, I went to the wrong place.
"Are you done with San Lang's court matters?" Empress Wang stuck out her belly and held a loudspeaker in her hand. It was the kind that was charged.
Li Yi gave it to Li Chengqi. Li Chengqi said that he would return it to Li Yi after using it. In the end, it ended up in Empress Wang's hands.
Empress Wang was listening to music. It was a Buddhist chant. Originally, prenatal education was for others to sing. With the new device, she recorded it.
"Why are you holding it? It's heavy." Li Longji naturally couldn't say that he wanted to find another woman and came to her in a daze.
However, he felt relieved when he saw Empress Wang.
"I'm exercising. Uncle said that I can't be lazy all the time. It's not good for the baby." Empress Wang turned off the loudspeaker and said with a smile.
The palace maid beside her took the loudspeaker and followed nearby.
Li Longji and Empress Wang went in. A palace maid brought in warm watermelon juice.
"Bring the black bean sauce and cucumber. I want to eat two mouthfuls. I want the black bean sauce that is fried with green onion and oil."
Empress Wang didn't want to drink the watermelon juice. She felt that it was tasteless in her mouth and chose the cucumber dip.
"Let's rest early today. We'll go to Zhuangzi tomorrow morning." Li Longji wanted to go out. There was nothing fun to do elsewhere. He wanted to find Li Yi.
