In the Tang Dynasty, once the number of girls decreased, it would affect the population, so once girls were widowed, they would be forced to marry another person to increase the fertility rate.

The population of Datang is very small, and wanting to increase the population has become a demand at the national level, but the rulers at this time are relatively unknowledgeable and have enough consultants, or the technology at this time is not up to par, so they come up with such a way to kill girls.

Young girls, if they are allowed to give birth a few years later, can reduce such mortality.

As long as people don't die, with the traditional idea of having more children and grandchildren, the population will not increase soon.

Women can also continue to give birth and have children for the rest of their lives.

If you think about it this way, girls can't live a good life.

The average girl in the feudal era is really pitiful.

However, the existing traditional habits are basically very difficult for even the emperor to change, because this is their very stubborn idea.

Typhoid fever can indeed be infected, but it is not a serious illness for Fan Jingjing.

Typhoid fever is a cold, but the symptoms of a cold can represent many physical ailments.

The beginning of the cold can be a simple cold, which can be survived with the body's resistance.

A cold can also be a sign of weakness, and a sign of weakness must be found out the cause, otherwise it will be very bad for yourself.

Niu Feiling believes that Fan Jingjing is definitely taking care of her son, although Niu Feiling has a lot of sons, and even many daughters, but the cultivation method is absolutely different.

Compared with the eldest son, the other children are more doting in their care.

Children who have a lot of resources to use may develop a big boy temper once they are spoiled, that is, they can easily become a gentleman.

If you still refuse to let people meet, it is really typhoid fever, but typhoid fever is a serious disease of poor families, for a rich and healthy rich son, Fan Jingjing does not think it is too serious a problem.

Of course, typhoid fever is not too big a problem for other people, even Fan Jingjing, but it is a big problem for Fan Jingjing's four children.

However, this time I came here to let Niu Shijin meet his four lovely children and see if he had any ideas, so Fan Jingjing still asked Niu Feiling to arrange for two or six people to meet.

Fan Jingjing remembered that she once gave the Niu family a large piece of glass, and she didn't know how to use this large piece of glass, and through the isolation of the glass, it shouldn't be too much of a problem to build a patient who would be infectious.

As long as you keep your distance so that the foam can't be infected, you basically won't be infected with Fan Jingjing.

I tried hard to recall whether the cold was droplet infection, as long as no one walked around at the time, it would be fine to bring the droplets over, so Fan Jingjing was still very confident in the four children.

In fact, the greatest source of confidence should be the clothes that the child wears.

In fact, even if there is no glass isolation, with the bubble pack, there should be no problem with close contact.

When she went out, she had the problem of preventing infectious diseases, so she brought all the bubble suits with her.

Of course, when you go out in normal times, especially when you enter someone else's house, you won't put on the bubble suit.

Fan Jingjing has never taken her children to visit other people's homes at all.

Fan Jingjing also brought a new bubble.

Fan Jingjing has another storage when the bubbles bear fruit, and there are always plenty of bubbles to use.

Once there are many, they will be given to others as a reward.

People are very fond of bubble rewards because they are a reward that money can't buy, and it can make life comfortable.

You must know that it is very difficult for Datang to stop mosquitoes and flies.

When sleeping at night, if no one is fanning the wind next to them, many rich children will not be able to sleep peacefully in bed.

There are more mosquitoes and flies in the Datang era than in the technological era.

Of course, the antibodies of antibiotics in this era are not so strong, and it is relatively easy to eliminate, because there are no strong factors in the general environment for these mosquitoes to rapidly undergo genetic mutations.

If mosquitoes and flies are in danger of extinction, I don't know how mosquitoes sense the crisis of the race.

Mosquitoes have a lot of genetic mutations, with genetic mutations, although some mosquitoes and flies will lose the ability to live, but some will find a better ability to survive.

Although it will become more different in appearance, but except for humans, other species are unlikely to have group rejection, and even if they are rejected, they will obediently obey under the violent beating of force.

Therefore, the new mutation factors are often more powerful than the attack ability, otherwise unless the people of the same race die, it is really difficult to survive.

If you don't have a strong ability to attack, you may have perished before it can affect humans, or before it was attacked, it was regarded by you as similar to the previous mosquitoes and flies, or even weaker, and you can deal with it with ordinary means, and you won't notice the changes in the species around you.

Often, because species have caused human trouble, people have to find ways to deal with new species, or even extinct new species, eliminating the survival of this race.

For humans, it seems that only species that can be raised can allow each other to continue to survive.

If there is a species in the territory that he does not allow them to live, this species will be constantly eliminated, because the space of the earth is limited, and in the limited space, human beings must constantly satisfy their own lives.

Anyway, Fan Jingjing is not prepared to harm these viruses, bacteria, mosquitoes and flies, she just wants to protect her children from bites.

In fact, she smeared some mosquito repellent on her body, and in the Niu Family Manor, Fan Jingjing also felt the infestation of mosquitoes and flies, and thought that mosquitoes and flies could transmit many diseases.

Fan Jingjing has a shadow every day before going to bed, worried about what if she is infected with an infectious disease and there is no way to relieve it and die?

In the past, if she died, she would die, but now she is worried about the child, but she feels that the child can live well in the Fan family manor.

In the feudal period, the mortality rate of people was very high, not that the early people were really so weak, but these infectious diseases, all kinds of vector mosquitoes, even if you have a strong body, you may not be able to resist it.

When a person dies, if it is the main labor force in the family, the rest of the family dies with it.

Death is so simple.

In the age of technology, we will try to save human deaths and make people feel compassion, but it is very difficult to have compassion in this era.

Because the result of your sympathy for others may be your own life, and there is no way to guarantee it.
