It can even be said that in the reference book given by Fan Jingjing, almost every question raised is a science, and you can study a science.

So although Fan Jingjing is not personally involved, but their respect for Fan Jingjing is getting higher and higher, think about such a powerful leader, if they can't reach the first family of the Tang Dynasty, it is their fault, although they are not surnamed Fan, but the Fan family manor is their common name.

In the future, if they get Fan Jingjing's permission, they may change their surname to Fan, and then regard changing their surname as the greatest kindness.

However, changing the surname is this kind of thing, and the family will generally oppose it, but. If there is a particular reason to change the surname, people will only feel compliance.

It's just that the surname Fan is not very special, maybe they can come with a new surname.

But now they can't think about it so much, and now they have to think about how to make food that can meet the needs of these livestock and transport it to Chang'an or other markets at the lowest cost.

In fact, in the current situation, if it is a horse or a cow, there is a market at all, the horse is an important means of transportation, the ox is an important tool for farming, and even in some places you can use a horse instead of a cow, but the cost of a horse is much higher than that of a cow, and a horse will be used to bring it. The number of cattle is completely insufficient, and the number of horses is sufficient, but this kind of horse is not able to face it.

Normal horses are slave horses, and they are not as fast, but they can do hard work and will not protest with you.

But even these horses eat more forage than cattle or sheep, otherwise they will be weak and malnourished, in which case people still prefer to raise cattle.

However, in the feeding of cattle, if you want to pursue meat quality, this feeding method will have a very big problem. Fan Jingjing knows that it is forbidden to slaughter cattle in Datang now, and one method is to directly slaughter the cattle outside and then transport them, and the other method is to introduce some calves after the cattle are introduced, and then let them go to the field to farm.

And after the number is sufficient, report to the imperial court, and then let these cattle become people's meat.

Beef is not the same as regular pork when cooked.

Beef is difficult to cook, but if it is cooked too well, the hardness of the beef will be very hard, so it is necessary to grasp the time when the beef is cooked.

All in all, in this day and age, cooking has been going on for a long time, and more fuel has to be used for more firewood.

Now that the number of people in Datang is very small, the firewood problem is still very easy to solve, except for some overdeveloped places, there is no firewood problem.

The demand for firewood in large cities is very high, and the continuous commercial felling of firewood around the city will also pose a problem of firewood loss.

After all, the best firewood is the wood that the trees naturally shed, so as not to harm the natural forest.

When the population was very large, there were not so many trees falling off, so people had to use them, cut down the trees, and when the trees were cut down, the large ones could be used as building materials, and the small ones could become materials for fire.

However, this way of burning fire will also have a very large impact on the environment, and when every household in Chang'an burns fire, you can find that Chang'an has become an environmentally polluted place.

But even if coal is used instead of firewood, that is, another more serious pollution, can make the whole city dark and gloomy can not be discharged, the best way to start a fire is that the gas stove is relatively clean, and there is no peculiar smell, but the gas itself is a dangerous item, can not easily contact the fire.

Fan Jingjing also knew that it was very difficult to do everything well, and she had to take her time one by one, but she didn't have much time.

Fan's Manor almost everything goes hand in hand, so that it has the current scale, and the current production practices, and the workshop is researching new things almost every day, and the things produced will only get better and better, and there is no repetition, which is actually a very big challenge for the workers of the workshop.

The development of the Northwest Business Line is not to sell the things of the Fan Family Manor, although it is also possible to sell the things of the Fan Family Manor to the Northwest, but it is more important to introduce external things and obtain more profits, because if there is no more profit, the whole business will not be able to continue to enter, and there will be no way to really stabilize this business road and give more development.

The development process is a long-term plan, so they have to design the entire schedule to implement the plan.

At first, it was indeed the simplest, which was to let the cattle come over, and they could eat the grass produced by the Fan family manor along the way, instead of ordinary or eating corn.

Although many people think that it is really a waste to let the cattle eat corn, but thinking that these cattle are actually very expensive items, they feel that they can accept it, but the distance is a bit far, but Chang'an is already a relatively close place to the northwest, and if you want to go to the northwest and bring these cattle in, it will not take too long to walk, but there is also a problem that they must have people who drive cattle.

But if you let the Turks enter the customs, the problem may be very big, and most of the merchants in the Western Regions are actually not trustworthy, he does business with you, if he can take the money, he will basically do business with you, but if there is no money to take, he may come to rob you.

Business is actually a kind of robbery at some point, and it is similar to the sea, if you can do business with a friendly person, you can do business with a friendly person.

If you can make people disappear in the sea or disappear in the desert, it is a matter of seconds.

For them, life actually lasts in a constant struggle, and after the struggle, after victory, they can make a lot of money when they reach their market.

The main reason why businessmen who go far away in this era are willing to spend a year or two to take this part of the road to do this part of the business, and take so many risks, is that it is a million profits.

But when the traffic is getting better and better, the price difference of goods is not so big, and it is more and more difficult to make a profit, because people are actually very good at calculating, if you transport the speed and the method of your transportation can reduce the cost. Some people will start to reduce prices for the sake of commercial competition, unless you have already said that you will not reduce prices, but if you do not reduce prices and do not compete, you may have to start all kinds of competition at the source.

In the Tang Dynasty, there is still silk that will make people compete, but silk is not something that the Fan family manor can control.
