It’s not like a fifty-year-old official in his later generations, the peak of his life has not yet arrived.

Historically, Li Shimin died in the 23rd year of Zhenguan.

It can be imagined that his physical condition is not very good at this time.

Otherwise, he would not have started to have the idea of ​​abdicating the throne to Li Kuan and traveling around the world with a few ministers.

"You can take a look at the memorials in that corner by yourself. During this period, you have not attended a few meetings in total, and many people in the court are dissatisfied with it."

Li Shimin took the pipe, took a very appropriate breath, and then signaled to leave and looked at the pile of memorials in the corner of the room.

Without further ado, Li Kuan also guessed that those memorials that must have been impeached by him.

It seems that everyone is wasting paper.

"Father, you are the Dinghai Sword in the court. It will be no effect whether your son will attend the court meeting.

While there is still some time now, Erchen wants to personally lead everyone in the laboratory to create something that is of practical significance to the people and the Tang Dynasty.

It may become more and more difficult to have such time in the future.”

Li Kuan naturally knew that Li Shimin said this, and in fact he also expressed that he was a little dissatisfied with the situation.

So naturally, I need to explain it roughly at this time.

"Although tea eggs and braised pork are of some use to the people, their uses are very limited.

In other words, the role of matches is a little stronger, but it is not worth your time to go to Guanshishan Academy every day.

Kuan'er, you are now the prince of the Tang Dynasty, so you must play an example of your application.

People say that new officials have three fires, but you haven’t burned them yet. When do you want to wait?"

Li Shimin obviously did not plan to continue to herd sheep.

If Li Kuan didn't make something out today, it would obviously be impossible to pass the test so easily.

Fortunately, on the way to the palace, Lan He also briefly mentioned the background and purpose of Li Shimin finding him today.

Li Kuan, who has a clear mind, is naturally at ease when speaking.

"Father, my son often went to visit Shishan Academy during this period. In addition to studying some new substances with the people of the School of Chemistry, he was also planning a major event with the people of the School of Finance and Economics, and a major event closely related to the rule of the Tang Dynasty."

Since Li Shimin wanted to make himself less angry, Li Kuan felt that some things could be thrown out first.

Anyway, it is not something that can be done in a day or two, so it will have no effect if it spreads earlier.

"Oh? Take this seriously? Then let me tell you."

Obviously, Li Shimin felt that Li Kuan was fooling him and was just an excuse to find.

"After so many years of development, Guanshishan Academy has gathered a group of the most powerful mathematicians in our Tang Dynasty.

However, these people often focus on math and do not associate math with real life.

It just so happened that the minister was planning a major event recently, which required a large number of use of the teaching and students of the School of Calculation, so he communicated with them more."

Li Kuan quickly mentioned something he had prepared to do after he ascended the throne to explain today.

Anyway, doing this thing early will only benefit, not harm.

If you grasp the actual situation of the Tang Dynasty earlier, your future policies will be more targeted.

"What's the big deal?"

“Population survey!”

“Population survey?”

Li Shimin thought Li Kuan would say something special, but four words appeared.

Just literally, you can know what Li Kuan wants to do.

In Li Shimin's opinion, although this matter is still important, it is not so important to the point of being particularly important.

"Yes! After twenty-one years of development, the Tang Dynasty has now completely entered the prosperous era of Zhenguan.

But in this prosperous era, how many people did the Tang Dynasty have and what the population composition of each prefecture and county are.

What is the number and gender structure of people of all ages, and how good is everyone's literacy level...

If the court can figure out these things, then they will have very important reference significance for the formulation of many policies."

Li Kuan knows the importance of a population survey than anyone else.

It has been more than ten years since I came to the Tang Dynasty. Li Kuan has never obtained a relatively accurate data on how many people there were in the Tang Dynasty.

Even if it is data in units of millions, no one can give it.

So the first big thing he wants to do is population survey.

Let’s first clarify the family background of the Tang Dynasty.

"The Tang Dynasty is so big, it will be very difficult to really figure out this problem.

Especially for many slaves in the homes of nobles and some mountain people, it is very difficult to investigate clearly.”

Li Shimin was naturally able to realize the significance of the population survey, but he obviously did not think that this job was that easy to do.

"That's right! It's because it's quite difficult that Erchen has not proposed it for a long time. Instead, he wants to discuss the plan with the people of Guanshishan Academy of Calculation and then formally propose it."

After Li Kuan explained this, Li Shimin would not be able to criticize anything else.
