Valley Emperor

Many things are inevitable caused by the environment. For the phenomenon of early marriage and early birth in the 16th century, later generations may find it strange and unacceptable, but it is the truth.

Even the Son of Heaven sometimes finds this fact strange, but he doesn't say much.

Because Li Xuan himself became a grandfather many years ago.

The eldest son of the emperor, King Li of Qi of Beihai Province, gave birth to his first son when he was sixteen years old in Xuanping twenty years. This is also Li Xuan's first grandson.

How old was Li Xuan at that time?

At that time, Li Xuan was only thirty-six years old!

And now, Li Xuan is only fifty-four years old, but his oldest grandson is eighteen, so what can Li Xuan say...

After all, early marriage and early birth is a common phenomenon these days, not only for the royal family, but also for the folks.

Nowadays, the general age of marriage for young men and women in the Tang Dynasty is about sixteen years old, and there is no distinction between high and low, regardless of whether they are royalty, nobles, ordinary citizens, or farmers.

Generally speaking, if you are seventeen or eighteen and have no in-laws (including engagement), you are basically an old girl, and the market situation is not very good.

But if it is released to future generations, at the age of seventeen or eighteen, he is still a student!

Therefore, in Datang, many students who are studying are often married when they are in middle school, and many of those who go to preparatory courses and go to college are married men.

This phenomenon has nothing to do with the so-called traditional concepts or ignorance. The most important thing is that people's average life expectancy is relatively low.

Therefore, many things cannot be simply seen on the surface, but must be deeply understood, and then you will find that the truth of the matter is often completely different from the appearance reflected on the surface.

Even now, the average life expectancy of Datang people is only about 40 years old, and this is the result of Datang's efforts for more than 20 years.

Looking at the contemporary world, the average life expectancy of forty-year-olds is the highest in the world, and there is no country or region whose average life expectancy can exceed the contemporary Tang Dynasty.

In some areas where there is no war, and the material conditions are relatively good, people may be in their thirties, but the average life expectancy in most areas is only about 30 years old, and in war-torn areas this number is not even 30 years old.

Datang was able to surpass other countries and regions in the world in one fell swoop, allowing the average life expectancy of the people of the empire to reach 40 years.

One of the biggest driving forces is, of course, the expansion of productivity.

Since Datang solved the problem of high-pressure steam engines and enabled high-pressure steam engines to be used as stable power for factories, ships and trains, the steaming revolution of Datang was officially launched.

Although Datang has been using low-pressure steam engines for a long time, it is only limited to small-scale use in mines, and its role is actually quite limited. Nineteen years before Xuanping, the main power of Datang's manufacturing industry was mainly water power.

It was not until nineteen years after Xuanping, when the high-pressure steam engine appeared, that the steam engine completely replaced the water power and became an industrial power.

The huge development of manufacturing and transportation also brought the Tang Empire into the era of steam.

Production efficiency has risen sharply, and a large number of industrial products have begun to flood every corner of society.

At the same time, it indirectly drives the abundance of living materials, especially food. According to the statistics of the Datang Household Department, the current per capita food consumption level of Datang far exceeds that of other countries and regions. , and the overseas mainland or overseas territories of some grain-producing regions, the number is even higher.

For example, in the Americas, the per capita grain has reached 800 kilograms, which is almost double that of the mainland.

In fact, in North America, especially the relatively well-developed Xinnanzhou, Sanhezhou and other areas, there are typically fewer people and more land, and they are all fertile fields. The local food is very abundant. The staple food of their three meals a day is already abundant, and they are more pursuing other foods such as meat.

The domestic area of ​​the empire can reach the consumption level of 400 kilograms of grain per capita, which is achieved through comprehensive efforts from various aspects, such as reclamation of wasteland, development of frontier areas, extensive use of bird dung fertilizer, investment in water conservancy and irrigation facilities, and construction of water conservancy and irrigation facilities from Southeast Asia and even from China. Large quantities of crops were brought back from the Americas.

It took a lot of hard work to reach this number.

But what about the rest of the contemporary era?

Datang officials in Europe once assessed the standard of living in Spain and came up with a figure of 200 kilograms!

Although this data is inaccurate and there are certain deviations, it can still reflect the living standard of contemporary Spaniards to a certain extent, and then infer the standard of the entire country.

The abundance of living materials is an important condition for increasing the average life expectancy of the population!

If you can't get enough to eat, how can you live longer!

In addition to the progress in eating, the increase in life expectancy in Datang is also due to advances in medicine.

There is no doubt about how important medical developments are to the development of life expectancy.

In order to promote the development of Datang Medicine, Datang has made great efforts, both in terms of manpower and funds.

Among the many research projects of the Royal Institute of Technology, many projects have a huge investment, but there has been little output, among which medical research is the absolute bulk.

Even other theoretical research, such as theoretical physics, has little output, but theoretical research relies on genius, and there is no need to conduct expensive experiments every day.

But medicine is different. It is very troublesome to study.

Not to mention all kinds of theoretical research, just looking for drugs is a huge trouble.

Datang's medical research has been walking on two legs for so many years. One is to sort out and study traditional Chinese medicine~www.wuxiaspot.com~ Sorting is nothing but sorting out prescriptions and then promoting them. Yes, the focus is on research, a group of people from the medical department are trying to understand the various treatments of Chinese medicine, including acupuncture and why Chinese medicine can cure diseases!

It is a pity that even in the 21st century, this problem cannot be understood, let alone the current Tang Dynasty.

However, they still achieved results, that is, although they still do not understand the principle, it is still possible to use some active ingredients from some traditional Chinese medicines to treat diseases.

One of the more important results is the extraction of quinine, which is extracted from the cinchona tree, because the people of the Tang Dynasty found that the cinchona tree has an excellent therapeutic effect on malaria. Quinine is extracted from the cinchona tree.

This thing is a huge progress for the medical development of Datang!

Especially for immigrants, quinine is an essential drug.
