Chapter 597

A country's population growth is related to many aspects. It is not simply that the country encourages more children, so that the country's population can be increased.

First of all, there should be enough men and women of school age, so that a couple can give birth to one person in about two years, and one million couples can add one million babies to the country. However, these one million babies will not be accurate data. We should take into account the sanitary conditions and delivery conditions, and even the health of the mother.

Until modern times, mothers who naturally gave birth to babies would be very dangerous. There were no mothers who died or died in childbirth, let alone in 348 A.D?

During the production process, the mother and child are safe, and how to raise children is a difficult problem. In an era of insufficient medical conditions, adults will die if they get a cold. Babies with weaker resistance will be in high danger as long as they get sick.

"... to increase the population, the big man needs to prepare too much." Ji Chang was full of embarrassment. He didn't dare to say to Liu Yan that he couldn't do it. He could only say the difficulties: "the first is food. People should have enough food at home before they dare to have more children."

Liu Yan nodded. Of course he knew that.

"Women are also labor. People do not have the qualification that women are pregnant and do not participate in labor. Even if it is near childbirth, it is still labor." Ji Chang was not born in an aristocratic family. In his early years, he was a local people. He was very clear about the living state of the farmhouse: "but there were many accidents during pregnancy."

To tell the truth, when Liu Yan was a child, his family also farmed. His mother also worked when she was pregnant with him. She didn't do less to bear the burden of cutting rice. Of course, she knew what was going on in people's families.

Modern medicine suggests pregnant women to exercise more, saying that more exercise is conducive to natural childbirth, but exercise and work are two concepts. Doctors suggest that more exercise is to walk more at most, but labor is to carry heavy loads and some more intense things.

For today's people, don't expect to avoid participating in production when you are pregnant. That's a blessing that can only be enjoyed by powerful, aristocratic and official young women. Therefore, the emergence of large-scale pregnant women in society is definitely a big or small thing.

Liu Yan thought of something and suddenly asked, "how's that kind of bean research going?"

Like many modern people, Liu Yan intentionally or unintentionally came into contact with too much information. Knowing that thing is one thing and how to do it is another thing, just as he can use mobile phones but doesn't know how to make mobile phones.

In fact, the so-called planting beans is to study how to use the pox on cattle to make vaccines. Liu Yan has no ability to do it himself. If he knows about it, he will write a charter. How to get results is the matter of the following people.

"Many prisoners of war died..." Ji Chang was actually full of doubt. He couldn't understand that vaccinating people's arms with cowpox could prevent smallpox from being infected: "but there are preliminary results."

Vaccinia vaccine? In fact, at the beginning, it was vaccinated from some people who got smallpox. It was first studied in Tianyi Dynasty in the 16th century. It was not until the end of the 18th century that a British doctor named Jenna developed bovine vaccinia. Until 1979, the World Health Organization solemnly declared that "smallpox is extinct on the earth", which is another great contribution made by Tianyi Dynasty to the world in addition to the four great inventions and rice hybridization. (but in fact, no one thanks Tianyi pilgrims, and thanks are also thanks to foreign devils)

Clinical trials are absolutely indispensable for the progress of medicine. Medicine began to enter the peak of research. That was during World War II. The Germans first carried out various experiments on prisoners of War (mostly Jews). The Japanese also carried out various experiments on Tianyi Korean (731), and even various countries carried out various experiments. Among them, the Americans had a big accident with their own soldiers.

If the state of Han wants to make progress in medical means, reliable or unreliable experiments certainly need living beings. It is better to take foreign prisoners as the test object than to operate with their own tongpao.

The law of the jungle is the truth. There is only a position without right or wrong. There are no human rights organizations now. The Han state can even do a large number of pit killings. Other things will not be taken seriously at all. It really responds to the saying "our hero, the other enemy".

Liu Yan was stunned immediately and asked angrily, "why didn't you say it earlier?"

Ji Chang quickly apologized, and then looked for a new topic.

Smallpox is actually a plague. In history, the outbreak of plague can always cause a sharp decline in large-scale population. The first nation to create the "biochemical virus" of plague is the Xiongnu. They used this self mutilation way to stop the pursuit and fierce attack of the Han Army after repeated defeat. For a period of time, the northern counties of the Western Han Dynasty suffered a lot, The Han Army, together with the expedition to the grassland, also suffered heavy losses.

In addition to the Huns, the most thorough use of "biochemical viruses" was the Mongolian Empire in the timuzhen period. When the Mongolian army encountered a siege, it was bound to collect corpses and throw them into the city, and use the original "biochemical offensive" to win the empire with the largest territory in the world. They can kill at least 200 million people in the era of cold weapons. The biggest means of killing is to create a plague, which is really unprecedented.

"... it is necessary to give the people the land to raise their children." Ji Chang just talked about how to encourage fertility. One suggestion is to reward land. He said solemnly: "the big man is constantly expanding, but there are no people living in too many places. Such expansion is only to increase the territory on the picture album, which is not beneficial to the country."

The territory of the state of Han is increasing all the time, but the population distribution is mostly concentrated in the abdomen. Among them, Qingzhou, which was first captured, has the most dense population. The second most populous state is Yangzhou, which was soon established, and Yuzhou is the third. Among the remaining states, Guanzhong, Bingzhou, Shuozhou, Jiangzhou and Guangzhou have the least population.

According to the census data, Qingzhou alone accounted for more than 4 million. That was an effect of Liu Yan's early use of Qingzhou as the basic plate. Waiting for the center to be relocated to Xiangguo has driven some population flows, but the diversion of Qingzhou's population is actually very limited.

There was a city in Yangzhou called Jiankang. During the period when Jiankang was the capital of the small imperial court of the Eastern Jin Dynasty, the population exceeded 1.7 million. If history had not changed, the peak would be 2.3 million.

Yangzhou has 1.7 million people only in Jiankang city. As the capital of a country, the development around the city must be good. The density of counties is much higher than that of previous dynasties. The population of the small imperial court in the Eastern Jin Dynasty is almost crowded in one state, and the more southward and southwestern the other counties are, the more sparsely populated they are.

Hearing that "there is no practical interest in the country" made Liu Yan's cheek twitch a few times, but he had nothing to refute.

The territory of each dynasty varies from large to small. The more the center of the Empire, the more the population must be. Then, the more the frontier, the more vast the territory and sparsely populated. This has not changed even in modern times. Even a modern metropolis can top some remote provinces (States).

The current era is somewhat special. The Central Plains has been ruled by the Hu people for decades. The Hu people have long carried out the policy of reducing the number of Han people, so that the core area of the Central Plains is no longer a densely populated stage.

For example, during the reign of Shihu and shile, except that the settled population of Xiang state (including the surrounding areas) exceeded 3 million, the population distribution everywhere was actually very abnormal. The most exaggerated thing was that a certain area could not even see a person.

In addition to the state of Shijie Zhao, there are similar situations, including the small imperial court of the Eastern Jin Dynasty. Yangzhou was the most densely populated small imperial court in the Eastern Jin Dynasty, and Jiaozhi was the least populated. After the Han state took over the rule of Jiaozhi, there were only 211 poor Han and Miao people, not counting the statistics of the garrison.

"Then come up with effective and enforceable policies." Liu Yan agrees with the policy of giving land incentives for giving birth to children, and is equally worried about the abnormal population distribution: "the Center encourages people to migrate, but the effect..."

Ji Chang showed great joy without concealment. He has begun to think that the military of the Han country needs to be suppressed. Direct suppression is not a good way, but we can start from the land first, at least break the restriction that non military achievements can not get land first.

"All the officials must do their best..." Ji Chang paused and said intentionally or unintentionally: "the king plans to let the retired soldiers settle in place. That's a good way."

"Even so, how many people can be arranged?" Liu Yan is very clear about Ji Chang's careful thinking, but he doesn't intend to stop it at all. He is the ruler of the whole country. He is not the spokesman of the military alone. The balance between the two chambers is the way for the king: "the prime minister should know that only the source of retired soldiers is not enough!"

The king of a country began to think about balance, which was a good phenomenon for Ji Chang, but he didn't expect Liu Yan to go to the general's side to suppress him. He didn't even think that one day the status of civil servants could surpass that of military generals. He didn't even dare to ask for equality between civil and military, just because he knew that Liu Yan was a king who would never stop his ambition for land.

"The capital given to the people to support their families is not only in that three-thirds of an mu of land." Liu Yan never only focused on agricultural production. He said in a serious tone: "we have engaged in collective farms. In addition to doing farm work, there are manual production. The prime minister should pay equal attention to it and should not be careless."

Ji Chang understood Liu Yan's meaning very thoroughly, that is, pay equal attention to agriculture and industry. We should not only pay attention to agricultural production, but also not forget industrial development, and even notice the encouragement to business together.

"King, in the fourth year of Yuanshuo... The big man was short of food to the point where he needed to recruit..." Ji Chang was careful when he said this. He even swallowed a mouthful of saliva. After observing Liu Yan's face, he continued: "the first priority of the country is food. If there is no food, the people will be unstable. It is easy to cause social unrest. It is the primary event for the king to hope for population growth."

Liu Yan's face is twitching again. He knows a lot of things. How to govern a country is completely new. At least he doesn't have relevant training like some princes or children of aristocratic families since childhood. It's clear that some things can't be taken for granted.

Of course, food is the most important resource of a country. All development is based on the premise of sufficient food. It will be unrealistic to talk about industry before that. It is even necessary to suppress all matters that can affect agricultural production and specifically increase the working population participating in agricultural production.

"... when the army was conquering Linyi and Funan, it repeatedly seized a large amount of grain and sent it back to the Han nationality by sea, but..." Ji Chang said today that he was a little desperate. Regardless of Liu Yan's ugly face, he continued: "if you think that simply relying on looting can maintain the national food needs, the Han nationality is in danger."

The Han state robbed grain from the southwest in a year or two. In addition to farming, grain was used to obtain a large amount of seafood from the sea and rob livestock from the Hu people.

Although Liu Yan has restored the old land of the Han family to 7788, there are not many prefectures and counties that have developed agriculture again. Qingzhou is the best to recover. Yanzhou, Xuzhou and Yuzhou are also good after settling down, but Yanzhou is mountainous and has little output, and the grain output of Yuzhou is relatively considerable.

Liu Yan quickly reacted. He knew where Jichang's "boldness" today came from. It was the continuation of Shijie and Zhao. The state of Tuoba generation could not become a state, Zhang's cool state could not become a worry, and Murong Yan state was about to be expropriated. All kinds of signs showed that the Han army could expropriate fewer and fewer enemy countries, and civil servants wanted to focus on the internal affairs of the country.

"There are a lot of arable land in the Han Dynasty, but there are really no people in those places. The grassland is not a place without output. It can graze and maintain the needs of military horses. Cattle can be used for production and eat their meat, sheep can spin and eat their meat..." Ji Chang said very sincerely: "a hundred wastes need to be revived, my Lord!"

Liu Yan smiled, not a smile of negative emotion.

At present, the distinction between civil and military affairs is not so big. There is no actual division of civil service groups or military general groups. It belongs to a beautiful era when Marco was the general and dismounted to govern politics. There are conflicts between them, not for the sake of strife.

Liu Yanzhi smiles because he is happy to know that the grassland is not regarded as a burden in China. He knows how to use the grassland from the aspects of textile, dairy industry and meat industry. Then the grassland is no longer a pity for the country.

The threat of the Central Plains Dynasty has always been in the north. Many dynasties are not unable to attack the grassland. They really don't know how to use the grassland after it is destroyed. As a result, they don't cherish it after it is destroyed. After killing one alien race, another alien race is born. They are attacked and destroyed from the grassland again and again.

"I heard that there are other countries to the west of the western regions. Wu SunJian was in the early Han Dynasty, and the remnants of the Dayue family established their country. There is also the Sasan Kingdom (Sasan Dynasty), a descendant of Sabbath. Further away, there is a sea, which is the inner sea of the great Qin Dynasty. The great Qin Dynasty is not the Pre-Qin Dynasty, but a thousand year empire..." Ji Chang didn't know where he got the news. He talked about it for a long time. Some of them didn't even listen to Liu Yan. Then he changed his mind: "I am convinced that the king said that the world is far greater than the 'world' in the mouth of ancient sages. The king is willing to make the sunshine shine on the Han soil, but if internal affairs are not cured, why should soldiers come out everywhere?"
