Li Shimin said in a deep voice: "The matter of marriage is not a trivial matter, but it is related to the stability of the country's society, down to the ordinary people, up to the backyard of the palace, all I want is to be home and everything is prosperous, self-cultivation and family governance of the country and the world, if the family is not peaceful, how can I serve the country with peace of mind, today's matter of the Hu family's daughter, let me be alert, since there are many marriage problems in the world, how can I sit idly by." ”

"Your Majesty Shengming!" The ministers immediately said respectfully.

Even Quan Wanji has nothing to say, even the most stubborn person wants to be harmonious in his family, and his father and son are filial.

Li Shimin looked around, looked at Merton and said with anger: "Merton, since this matter is caused by you, let you tell me, what are the flaws in my Tang marriage?" ”..

Morton didn't know that he had been exposed, and said confidently: "First, close relatives and close relatives get married, second, early marriage, third is the finger belly for the marriage doll, the fourth is the child daughter-in-law, the fifth is the arranged marriage, and the last is the interference of the parents in the marriage." ”

As soon as Merton's voice fell, the hearts of the ministers were heavy, who would have thought that under the tradition of the words of the matchmaker of his parents, so many problems would be hidden.

Li Shimin's hands trembled, and he paused: "Let's all discuss it!" If there are any problems, you can confront Merton face to face, and today we will solve all the problems one by one, and give the men and women in the world a good relationship. ”

All the ministers looked at each other silently, looking around,

The eldest grandson Wuji gritted his teeth and said: "Back to the emperor, Weichen believes that the marriage of close relatives is very harmful, according to Weichen's investigation, many couples who marry close relatives, their children are disabled and stupid, and there are many people who die of illness, and the harm is great, and I also ask Your Majesty to order it to be announced to the world, and it is expressly prohibited." ”

The marriage between Changsun Chong and Princess Changle has been dissolved for nearly a year, and it is no longer a problem to mention it at this moment, and it is most appropriate for him to take the initiative to mention it.

In fact, for Merton's revelation that close relatives got married, although the eldest grandson Wuji resented Morton for making the eldest grandson family lose the opportunity to become rich for a hundred years, but there was no trace of luck, the eldest grandson family has developed into a behemoth now, if the future eldest grandson family is run by a fool, I am afraid that is the future of the eldest grandson family.

Li Shimin glanced at the eldest grandson Wuji with satisfaction, although the marriage of close relatives involved the eldest grandson Chong and Princess Changle was suppressed, but it is impossible to delay it indefinitely, although the ink magazine has spread the harm of close relatives marriage among the people, but the effect is not obvious, and there are still many people in the folk close relatives marriage.

"In this case, when the eldest grandson Aiqing revised the Zhenguan Law, he added this prohibition to all relatives who are within five generations of the direct line and within three generations of the side lineage are not allowed to marry." Li Shimin nodded.

"Wechen obeys!" The eldest grandson Wuji breathed a sigh of relief, and then retreated.

"Regarding early marriage, Weichen has some doubts." As soon as the eldest grandson Wuji retired, Quan Wanji immediately stepped out.

"Quan Aiqing, please speak." Li Shimin said.

Quan Wanji nodded and said: "Back to Your Majesty, the law of my dynasty stipulates that men and women can get married at fifteen, but the doctor thinks that men and women need to complete their physical development before they can get married, I'm afraid it's inappropriate." ”

"Developmental, how old is that?" Li Shimin frowned, turned his head to look at Merton and asked:

Merton said in his heart: "Eighteen years old." ”

Li Shimin suddenly breathed a sigh of relief in his heart, but before he could relax, he heard Merton continue: "It's not a virtual year, but a year old." ”

"One year old?" The ministers wondered.

Merton explained: "The current calculation of age in the Tang Dynasty is to use imaginary years, birth is one year old, and one year is added every Spring Festival, doctors think that this calculation of age is extremely inappropriate, if a baby is born on Chinese New Year's Eve, another baby is born during the Spring Festival, the two are one day apart, but the difference in calculation is one year, if it is the same year, one year, one year, one year at the end of the year, the same age but one is staggering, the other is still in swaddling." ”

Merton's explanation was clear, and the ministers couldn't help but nod their heads again and again.

"The doctor's calculation of age is from the date of birth, until the birthday a year later, the first year is counted, that is, the imaginary age of fifteen years of marriage stipulated by my dynasty, and in the eyes of the doctor, it is only thirteen years old." Merton said bitterly.

"Thirteen!" Li Shimin's heart suddenly fluttered, he was already married at the age of thirteen as a child, no wonder the doctor reacted so much.

"The minister is against!" Quan Wanji said loudly.

"Since the end of the Sui Dynasty, the population of our dynasty has withered, the land is barren, the Emperor Taishang and His Majesty have recuperated, and the population has gradually recovered, but it is still not as good as the previous dynasty, if the woman gets married at the age of eighteen, the population growth of my Tang Dynasty will definitely be greatly reduced, and then there will be a shortage of men, which is a threat to the imperial court!" Quan Wanji shouted loudly, eighteen years old, isn't that twenty years old, in the current situation of Datang, she is already the mother of several babies.

At this time, the population is the labor force, which can create wealth, there are taxes, there are troops, and the rulers often encourage early marriage in order to increase the population.

Merton retorted: "Early marriage is very harmful, according to the statistics of doctors, early marriage women have difficult births, one corpse and two lives are countless, so instead of increasing the population, it is counterproductive, as for the population growth, and with the prosperity of doctors, the future infant mortality will definitely be greatly reduced, and the survival rate of children will be greatly increased, and then Your Majesty will probably have to consider how to accommodate so many newborn people." ”

As a master of gynecology and pediatrics, Sun Simiao has begun to write medical books on obstetrics and gynecology, and began to teach female doctors in women's medical colleges.

"Suppose a woman gets married at the age of eighteen, has five children in her life, can have five generations in a hundred years, and has nearly 100 people in the same house for four generations."

The Ministry of Civil Affairs Shangshu Dai Xuan nodded, the Ministry of Civil Affairs is responsible for the statistics of household registration in the world, in some rich and noble families, the population of the four generations in the same house really has a population of hundreds of people.

"And so on for the entire Tang Dynasty, the population will double every 20 to 40 years. At present, my Datang has a population of 3.8 million households, a population of 20 million, a population of 40 million in 20 years, and a population of hundreds of millions in a hundred years. Merton's voice was sonorous, shaking the court like thunder.

"Hundreds of millions of people?" The Manchu officials suddenly looked at Merton in disbelief

Li Shimin was shocked, and immediately set his eyes on Dai Guan, the secretary of the Ministry of Civil Affairs.

Dai Xuan hurriedly leaned over and counted on the Chaohu, the more he calculated, the more frightened he became, and after a while, he was already sweating profusely, and after a long time, he got up with a wry smile and said: "If the doctor can ensure the survival rate of newborns, the population of my dynasty may be able to reach hundreds of millions in a hundred years." ”

The Manchu ministers suddenly gasped, before this they were worried that delaying the marriage age of women would be detrimental to population growth, and at this moment, this worry has long disappeared.

If there are more people and less land, and the land output cannot feed so many people, I am afraid that when the time comes, the people will not have a good life, and the rebellion at the end of the Sui Dynasty will definitely be repeated in the Tang Dynasty.

Merton nodded secretly, he knew how grim the population growth rate was, in the later Tang Xuanzong period, the population had reached more than 80 million, if there was a doctor's advancement, it was not impossible for the population of the Tang Dynasty to exceed 100 million.
