Wei Zheng and they all said goodbye, Li Shimin and their side were much more casual, they greeted their respective concubines and so on, and let the three of them greet Li Yuan first, and then chatted with their respective mothers and concubines for more than an hour, and the father and son sat down in the study.

However, looking at the sitting posture of the three of them, with their waists straight, Li Shimin couldn't help but smile and said: "Although it has been six years since you left, you were not so restrained with me before you left, relax a little, speaking of which, this sofa was still transported from Huo Gang and improved, and you are not so unfamiliar with it." ”

"What my father said is, but we are just used to it, and after six years of military career, these habits have long been engraved in our bones." Li Chengqian smiled bitterly and let himself relax a little.

"Oh? Six years? Didn't you stay in the barracks for less than half a year? Li Shimin looked at them curiously and asked.

"That's right, but the teacher told us that we should always demand ourselves with the virtues of a soldier, and the so-called body is the capital of everything, so even when we are studying, we must also carry out military training, including all daily behavior and habits that are no different from those in the barracks." Li Chengqian said seriously.

"Yes, your body is indeed much stronger now, which is stronger than when my father led the troops to fight." Li Shimin couldn't help but look at the bodies of his three sons, and then said with a smile.

In addition to Li Ke, Li Chengqian and Li Tai were not in good health when they were children, especially Li Tai, who was slightly chubby since he was a child, like a little fat man, but now the three of them look like real men, just look at their arms are very thick, and sitting here, talking and so on are also full of energy.

This body is really much stronger and healthier, and many of the problems when I was a child are obviously gone.

"I don't dare to compare with my father." Li Chengqian said with a smile.

"Okay, don't pat me on the back, how about it, you've been studying for six years, tell me how you feel?" Li Shimin looked at the three of them and spoke.

"Father doesn't know where to start?" Li Chengqian thought about it, six years of life, there is too much to say, but he doesn't know where to start.

"What do you think of and say anything, in this way, just tell me how many things you think you have learned from Huo Gang after studying for six years?" Li Shimin asked.

"Father, do you want me to tell the truth?" Li Chengqian thought for a while and said.

"Tell the truth." Li Shimin nodded.

"To tell you the truth, father, after six years of study, we think we have learned too many things, I believe that Li Tai and Li Ke feel the same as me, but even so, our feelings are still unfathomable, because too many things on the teacher are not at all we can learn in a short period of time, I think, if we want to talk about these learning completely, it is difficult to do this without ten or twenty years. Of course, this is just our estimate. Li Chengqian said seriously.

Li Shimin was stunned for a moment, more than ten or twenty years? Even some great Confucians didn't dare to say this, he subconsciously looked at Li Tai and Li Ke.

"Big brother is right, this is just knowledge, if the teacher even teaches us how to behave and do things, then we feel that we may not be able to learn all of our lives." Li Ke also spoke.

"Yes, but when we came back, the teacher also said that what we learned was almost enough for how to be an emperor and the leader of a country, and he couldn't teach us more things, and we needed to understand what he said in the process of managing a country."

"As for more specialized knowledge, the teacher said that those knowledge requires professional people to spend their whole lives studying, and new students are constantly being added to it." Li Tai also nodded and spoke.

Li Shimin nodded thoughtfully, he knew that what Li Tai was talking about should be those professional knowledge, such as what those craftsmen want to learn, Datang should actually join in, but Datang's social status has basically been fixed, if you want to increase a class, how difficult is it?

Because the resources of the society are fixed, and if there are more people to share, then others will be less, so although Li Shimin is constantly promoting other things, it is difficult in this regard, and it is not only craftsmen.

Including the content of free learning, although there have always been arithmetic and other aspects, but it is still mainly learned by saints, and I want to change this...... It's even harder, because it's these Confucian students who control the whole mainstream of society, and you suddenly want to tear them off the altar, and no one wants to.

Therefore, Li Shimin can only continue to promote the number of poor students now, and when the number of these poor students increases, they will not be like a family of door valves, and it will be better to reform when the time comes.

"In this way, you can talk about the gap between our Datang and Dahan now, you should feel this very deeply." Li Shimin thought about it and raised a new question.

"There's a big gap." Li Chengqian was blunt and spoke directly.

"Exactly?" Li Shimin thought for a while and said.

"According to the news released by Dahan's Ministry of Agriculture last year, Dahan's staple grain last year's total income, wheat, did not increase much compared with previous years, about 3.2 billion kilograms, but Dahan's population is currently only 4 million people, and last year's Dahan exported grain to Datang can feed about 10 million people, and it is the kind of food that is full."

"But this is just the food that Datang needs, in fact, Dahan is exporting more than 10 million people of food, Dahan himself can still balance a very terrifying amount, and these grains in addition to leaving strategic reserves, the rest of the grain is raised a large number of pigs, cattle, sheep, chickens, ducks, fish and other meat breeding, there is a large number of wine, after the winemaking extraction of a large amount of high-concentration alcohol, used to treat wounds and other disinfection use."

"But the population of Dahan who is responsible for growing food is only about 800,000 people, that is, the land planted by 800,000 people feeds more than 15 million people, and it is more than enough, according to the current grain production of Dahan, even if there are 10 million more people, in the current state, Dahan can afford to raise, and it is very easy."

"This is just the staple food I said, in addition, Dahan has also developed a lot of foods that have been changed according to food, such as vermicelli, cold skin, gluten and other special foods, although these foods consume more food, but they enrich the diet of the people."

"Of course, the most important thing is that the people of Dahan can afford to eat meat! For the most ordinary people, almost every year, they can kill a pig of about 300 catties, and turn these pork into cured pork by refining oil, so that the preserved oil can make them not lack oil and water all year round. ”

"In the daily process, they also have chickens and ducks raised at home, they can eat eggs, duck eggs, goose eggs and other eggs, and they can occasionally kill one or two chickens to supplement their meat."

"Although ordinary people don't dare to say that they eat meat at every meal, but it is certain that there is oil at every meal, and even some people raise more pigs, they can sell pigs to butchers in the city, and there are even special farms to raise pigs, I know that although pork is inferior meat in my Datang, but can ordinary people in my Datang afford to eat these inferior meat?"

"In fact, with the supplement of meat, the amount of food consumed will be reduced, and the physical fitness of the people of Dahan is far stronger than that of the people of Datang, and the most important thing is the average life expectancy."

"I have heard reports from the Ministry of Health of Dahan on this aspect, and in the past few years, no one has died due to natural disasters in Dahan! And many people in their forties, I have seen a lot, they look like we people in their thirties in the Tang Dynasty, because they have been fully supplemented with meat and grain, so they look young. ”

"According to the estimates of the Ministry of Health of Dahan, the average life expectancy of the people of Dahan can reach 60 years or even higher."

"We can't do that." Li Chengqian sighed and said.

In fact, Li Shimin knows a little bit about these data, because in recent years, all provinces and continents in Datang, especially some continents prone to natural disasters, have stored a large amount of grain, and these grains are all bought from Dahan, so Li Shimin knows that Dahan has a lot of grain.

But he didn't expect that the gap between the people of Dahan and Datang was already so big?

Is pork inferior meat? Li Shimin knows this very well, but it is just pulled out by these so-called nobles of the Tang Dynasty, if Li Shimin can let everyone in the Tang Dynasty eat this inferior meat, do you believe that he Li Shimin instantly gave birth to a Buddha? Straight sanctification?

The ordinary people of Datang don't say that they can eat meat every day, but they can eat meat for the New Year, and they are not hungry at ordinary times, so they are considered a good family.

But this is estimated to be the poorest family in Dahan!

"The teacher once said that being an emperor is simple and simple, difficult to say, difficult because a country has many problems to consider, and simple because if you can make all the people of a country live well, then any problem will not be a problem in front of you." Li Chengqian added.

Li Shimin was silent for a moment, this sentence sounds a little too general, but if you think about it carefully, why isn't it so? If he, Li Shimin, can make the people of the Tang Dynasty reach the level of the people of the Han Dynasty, who would dare to be presumptuous to him? Someone dares to be presumptuous, Li Shimin said a word, these people can tear him alive, and no one can stop him.
