Zhu Yuanzhang was shocked. In the past, when the state preceptor taught him to calculate, he thought it was just a casual lesson.
He did not expect mathematics to be so important to the state preceptor.
However, how could this mere mathematics help him make the right decision?
Zhu Yuanzhang asked.
Lu Ya smiled and said,
"The main point isn't mathematics. Mathematics is just a tool. The main point is the data.”
Zhu Yuanzhang was confused.
Lu Ya patiently explained,"
"Nothing in the world can escape from a number. War, tax collection, disaster relief, recording yellow books, and so on. To put it bluntly, it was data.”
"For example, the yellow register. It records the people's hometown, name, age, population, land, property, and household registration according to their occupation. It is mainly divided into three categories: civilian, military, and craftsman.”
Zhu Yuanzhang listened attentively, his brain working quickly, trying to keep up with Lu Ya's train of thought.
Lu Ya continued,"
"The yellow book of the Ming Dynasty records the population data of the military and civilians who are registered. These data are not cold numbers, but live people. They are like you, they have parents, wives and children, they can cry and laugh, they know what pain is, they know how to be afraid of death, they know how to live.”
“……”
All of a sudden, the hall fell silent.
Zhu Yuanzhang was also moved.
Lu Ya continued to speak with conviction,
" In the past, when the emperors were governing the country, they felt that these were cold numbers that they didn't need to care about at all. They felt that these people could be unimportant, and it didn't even matter if they died or not. But Chong Ba, as I said before, these numbers aren't empty things, but real lives.”
Zhu Yuanzhang's expression changed.
Lu Ya paused and changed his words.
"The income and expenditure of the national treasury are also data. It is related to the country's money and grain allocation, the national economy and the people's livelihood.”
"After you ascended the throne, the imperial court stored silver, silk, cloth, tea leaves, grain, refined salt, and so on from the two capitals and thirteen provinces.”
"These numbers involve dozens of types of resources. From income to expenditure, and finally, there was a surplus. When you had accurate data, you would be able to have an accurate comprehensive understanding of the situation of the entire Great Ming Dynasty.”
To govern a country, the first thing to understand was its productivity.
Then, how would one know about productivity?
Naturally, it was based on the annual income and surplus of the national treasury.
These things relied on boring data.
"Imperial Preceptor's words enlightened me.”Zhu Yuanzhang sighed. Every time he talked to Lu Ya, he would always obtain unexpected gains. These gains could not be seen from books.
Lu Ya smiled, knowing that Zhu Yuanzhang had taken his words in. He continued,
"The success or failure of governing a country is actually greatly related to the vast amount of grain, silk, and silver.”
" When you rule, whether the population increases, whether the national treasury is full, whether the grain is harvested, and so on, you can know everything through data. This will also help you enact national policies.”
"I'll remember what the state preceptor said. I'll work hard to study mathematics in the future and won't fall behind in this subject.”Zhu Yuanzhang said seriously.
Lu Ya nodded and smiled."
"That's good."
"Oh right, why did Imperial Preceptor enter the palace to look for us?”Zhu Yuanzhang didn't think that Lu Ya entered the palace just to tell him this.
Lu Ya smiled and did not answer. Instead, he took out a book from his pocket and handed it to Zhu Yuanzhang.
"This is the study plan that I have made for the Crown Prince. You are busy with government affairs during the day, so it is not appropriate for me to disturb you. I have chosen to come at this time. If you agree, let the Crown Prince come to the Stargazing Tower to find me tomorrow morning.”
Zhu Yuanzhang was stunned, but what followed was endless ecstasy. He said excitedly,
"State Preceptor, are you saying that you are willing to be the Crown Prince's teacher?”
"Yes." Lu Ya nodded.
"Good, great. I've always wanted Imperial Preceptor to teach the Crown Prince, but I didn't know how to say it. Now…I don't know what to say.”Zhu Yuanzhang said excitedly.
At this moment, Zhu Yuanzhang suddenly thought of something and said in embarrassment,
"State Preceptor, since teaching one is one, why don't you help us discipline the other four sons?”
"Hmm?" Lu Ya was stunned.
"Which four?"
"It's Zhu Shang, Zhu Gang, Zhu Di, and Zhu Su.”Zhu Yuanzhang said with a smile.
Lu Ya was speechless.
If he remembered correctly, even the youngest Zhu Xi was only nine years old.
Lu Ya was speechless. My mission was to teach the Crown Prince, but you stuffed so many little bastards into my mouth.
Just as Lu Ya was about to refuse, a thought suddenly flashed through his mind. He nodded and said,""Alright, I'll teach them all."
"Thank you, Imperial Preceptor!" Zhu Yuanzhang's face lit up.”
The two of them discussed for a while more before Lu Ya turned around and left.
"State Preceptor, tomorrow I will ask the Crown Prince to bring his four younger brothers to the Stargazing Tower to learn from you.”Zhu Yuanzhang said before Lu Ya left.
"Oh, alright, alright." Lu Ya waved his hand and quickly disappeared into the night.
