……

There are four blood types in people, namely A (a), B (B), C (O), and D (AB). When the agglutina in red blood cells binds to the corresponding lectin in serum, the red blood cells undergo an agglutination reaction, which agglutinates into lumps or granules. Based on this response, we can determine the blood type. In addition to the same type of blood, blood type A and B can also be transfused with blood type C, blood type D can be transfused with three other types of blood, and blood type C is the most picky and can only be transfused with blood type C.

Therefore, we sometimes call it the oil type, the villain is like oil, and there is no room for other ......"

When Li Dangzhi talks about medical knowledge, it is endless.

On that day, in addition to the "Classic of Materia Medica" and cowpox, Hua Tuo also talked about blood type. It has been a few years since the blood type was proposed. However, due to various reasons, the hospital has not been able to find simple and reliable blood tests and blood transfusions. It was only recently that there was a breakthrough. However, microscopes, steel needles and glass equipment are all valuable; There is also a shortage of manpower in the hospital. Blood group testing is still mainly carried out in the military. At present, it is a general school first, and after a period of time, it will be gradually extended to all soldiers. Each person will be given an identification plate with their blood type recorded in case of emergency. If it weren't for the general's family, where would it be the turn to get these children. In order to replenish the blood in time, even the servants were stained and their blood type was tested, which can be regarded as a person's enlightenment, and the chicken dog ascended to heaven.

It is worth mentioning that Hua Tuo once joked, saying that "Ding (AB) blood type is like a gentleman, the nature is like water, and any blood can be tolerated; And blood type C (O) is the most stingy. The nature is the same as oil, and no one can tolerate it except himself, and it is for the villain "Yunyun." Zhang Han found it funny, this comment was the opposite of later generations.

"What's the use of a blood type test? Can't you do it if you don't do it? ”

Eleven Lang is six years old this year, and when he saw his younger brother holding his fingers in his mouth, his eyes were shining, and he couldn't help but be a little stunned.

"That's not going to work! An adult is about two~three+ and is in danger of life. If at this time, his blood type is known, as long as the appropriate blood is transfused, his life can be saved......"

Li Dangzhi's smiling face, falling in the eyes of Eleven Lang, is really hateful. Seeing that he fished out a shiny steel needle from the boiling water, Eleven Lang couldn't help but tremble. I wanted to shrink behind Brother Ten. Juro pressed against his brother hard to prevent him from escaping. It's nothing to stumble and bleed on weekdays, but today he couldn't help but be a little apprehensive when he saw the shining steel needle.

"It's okay, little boy, it doesn't hurt ......"

Li Dangzhi quickly pulled Eleven Lang's little hand and stabbed him in the middle finger like lightning. Seeing the red blood beads gushing out, Eleven Lang couldn't help but wrinkle his little face.

"Does it hurt?"

Juro asked his brother with concern.

"It doesn't hurt!"

Eleven Lang's eyes were sparkling, and he said viciously.

Looking at his childish and cute appearance, Li couldn't help but smile a little.

……

Zhang Shen returned home. As soon as I entered the General's Mansion, I was taken aback, and I saw that the mansion was in a mess. I don't know what's going on. Reaching out to grab Liu Laifu who hurried by, Zhang Shen asked:

"Uncle Liu. What's going on? ”

"Is the eldest prince back?"

Liu Laifu looked up and saw that it was Zhang Shen, so he hurriedly saluted. Zhang Shen grabbed his arm and held him:

"Uncle Liu, what are you polite to me? What's going on? ”

“……”

Liu Laifu refused to obey his orders, forcibly gave a half-salute, and explained the matter again:

"The eldest prince came back just in time, let's check it together!"

……

"Big brother, big brother!"

The two were talking. Eleven Lang saw Zhang Shen and hurriedly drove his beloved fruit to dismount. Burst through with a puff of smoke and raised his bleeding fingers high.

Zhang Shen pinched his brother's little face, took his white and tender fingers in his mouth, sucked it, and blew again, "Does it hurt?" ”

"It doesn't hurt!"

Zhang Shen laughed and picked up his younger brother from the horse, lifting him half a day high. As the saying goes, an eldest brother is like a father. If he had been married early, his son would have been so old. Guan Xuan leaned in the carriage, watched her husband hug Eleven and kissed and kissed, and smiled sweetly with his hand on his lower abdomen -- this book is reprinted on the literary network -- After four years of marriage, she was finally pregnant.

"Here, this is the ...... your eldest brother bought for you"

Guan Xuan casually stuffed a crystal ball into Shilang. The crystal is crystal clear, and the price is not expensive, but the carefully polished 128 sides sparkle in the sun, which is extremely beautiful.

"Where is my land? What about mine? ”

Eleven asked eagerly.

"You can't do without it!"

Guan Xuan touched Eleven Lang's cheek with her fingers. There was a dimple on the baby's fat little face, Eleven Lang dodged, "Gege" smiled, but the two big eyes stared at her without blinking, indescribably cute.

"You!"

Guan Xuan touched it in her sleeve and took out a verdant jade apple. The apple was so lifelike that Eleven Lang swallowed and foamed at the mouth when he saw it.

"What are you doing down again?"

Zhang Shen carefully blamed his wife, he hated to take his wife in his mouth.

"I can't sit in the car all the time when I'm not home......"

Guan Xuan's heart was sweet, and she softly persuaded her husband not to worry.

"Eldest Prince, this is ...... I'll say hello to the two of you, it must be a young son, and Mrs. Ruo will be very happy......"

Liu Laifu is a clever person, and he quickly saw the details.

Zhang Shen was happy in his heart and smiled:

"Uncle Liu, accept your auspicious words, I brought a few mountain cocoons back, it's not a good thing, and please Uncle Liu don't dislike it......"

The mountain cocoon is the silk woven from silk, which is a specialty of Donglai, very tough, and not a precious thing. But many people are not to blame, Zhang Shen brings something up and down the house every time he comes back. After a long time, the top and bottom are very acknowledged by his affection.

Liu Laifu's eyes narrowed into a slit:

"Eldest prince, how embarrassing is this......"

……

"Good! Good! Bring the wine! That way, your mother can rest assured......"

Experience is the most cultivateable, Zhang Yu has a huge amount of money, and has dealt with all kinds of people for several years, and he has long been immature. Looking at the eldest son who was calm and gentle, Zhang Han was in a good mood. The eldest is married but has no children, the second child refuses to get married, Zhang Han doesn't mention it, and he has been thinking about it for a long time in private.

After drinking two glasses of cider with his son, Zhang Han asked him about his recent situation.

"Father, I'm not the same as before, I camp every day, and I'm busy for a few small money......"

Under the careful care of Xiang Feng, Sihai Qianzhuang has developed rapidly, and has been in 74 branches each. East to Qingzhou, west to Sanfu, south to Jiaozhu, north to Yan Dynasty, all the counties and cities under Zhang Han's influence have the semicolons of the four seas.

"Oh?" Zhang Han smiled and said: "You kid, if you earn a little money, then who else makes a lot of money?" ”

"Naturally, there are, for example, grandfathers......"

Zhang He holds the fleet, monopolizes most of the overseas trade, and has various workshops in his hands, with an annual income of between three and a half million yuan. Zhang Shen's business is big, and he met his grandfather, but it was Xiao Wu who met Da Wu.

When it came to his father, Zhang Han couldn't help frowning slightly. Zhang He has become more and more stingy in recent years, and even he, as a son, has difficulty getting money from him. I don't know why Zhang He saved so much money.

Zhang Han frowned and was relieved, no longer thinking about this headache. Zhang Shen naturally knew that there was a mustard between his father and ancestors, and it was not his turn to make irresponsible remarks about this matter, so he would not be bored with himself. There was a moment of silence in the room.

As soon as Zhang Han stretched out his hand, Zhang Shen hurriedly poured a glass of cider for his father. The sunlight shines obliquely, the white and delicate porcelain cup is as warm as jade, and the turquoise wine is like a flawless jade, which is very beautiful:

"Shen'er, I heard that Delong and a few other money banks had a run not long ago, and everything is okay in the four seas, right?"

"It's all right, father! Delong Qianzhuang's black eyes only saw silver, and no matter how much capital he had, he issued money tickets indiscriminately, and then the turnover was not effective. The mishandling led to a panic and all the depositors flocked to the place, wanting to withdraw their money......"

Qian Zhuang is very profitable, and naturally many people are optimistic about this cake. Of course, the capital of ordinary people is not as strong as that of the four seas, but there are still a lot of rich people, and several families get together, and this capital is about the same. Arguably. Sihai has encountered many strong competitors in its development. However, money comes quickly, and many people get carried away. Sihai Money Village has always had one money and issued two money tickets. In other words, the reserve for the Four Seas Money Ticket is 50%. And many money banks only have 30% or even 20% of their reserves. Once there is a credibility crisis. A run occurs. It is not possible to repay the cash in a timely manner. As a result, the credibility deteriorated, more depositors were run, and the turnover was insufficient, so they were forced to declare bankruptcy.

In the spring of this year, Delong, Guangfu and other money banks closed down one after another, which greatly affected the credibility of money tickets, and various money banks had runs of different scales. Fortunately, the reserves of the Four Seas Money Village are relatively high, and the treasury has been connected to Zhang Han's treasury. With Zhang Han's strong support, Sihai survived a short period of embarrassment. It is completely deposited and exchanged, and it has set up a golden signboard for full cash. Instead, they took the opportunity to expand their business. No, the run has passed. Zhang Shen now has free time to go home.

"That's good! That's good! ”

Zhang Han was thoughtful. If Sihai Qianzhuang is really embarrassed, Zhang Han will definitely help. He knew it and wasn't worried. But the collapse of Qianzhuang is widely implicated and is also a problem.

"Father, Qian Zhuang has a great influence, I think it is still necessary to regulate it......"

In Zhang Shen's view, the management of various money banks is chaotic. The impact of wanton issuing money tickets is too bad. He suggested. Establish a special agency to manage all money banks in a unified manner. For example, the reserve must be set at 50 per cent, and when the money bill is issued, the reserve must be handed over to the institution. After verification, the issuance will be granted.

“……”

Zhang Han nodded, and these words went to his heart. The establishment of a central bank is necessary. But how to proceed in the end, Zhang Hanxin didn't count. However, he also knew that it would definitely not work to let Sihai Money Bank manage it.

……

The two talked a few more words, and then they got to the point of Zhang Shen's visit today. It turns out that the development of Sihai Qianzhuang is booming, and the money is not enough. 100,000 yuan is a huge amount of money, but a peasant household that has reclaimed land has to borrow 10,000 yuan, and peasant households in various places need 35,000 yuan to borrow at a time, and this amount of money is about to be borrowed. As for the main business of the bank, it was able to collect some money, and the bank took the opportunity to issue a batch of money bills. That's how it persevered. Today, after the rapid development not long ago, Sihai Qian Zhuang is short of money. It is also unrealistic to ask Zhang Han to keep throwing money into it. Zhang Shen was willing to act as an agent for the distribution of military salaries, and gave extremely generous conditions.

"What? Shen'er, you said you don't want any fees, but really? ”

Zhang Han couldn't help but be surprised. At this moment, the military salary is mainly five baht and five baht gold. Long-distance transportation is not thousands of miles, requires a large number of people to escort it, and the cost during this period is also considerable.

"Father, can I still lie to you?"

Before Zhang Shen came, he had already discussed with Xiang Feng. Because transportation takes time, Dasi Nong Xu Ling will pay the generals into the money village some time in advance. In this way, there is a time lag between receiving the military salary from the money village and issuing the military salary. It is equivalent to saying that the money bank can use the military salary as its own money during this period. Moreover, the credibility of the Four Seas Money Bank is booming, and now the Four Seas money ticket can be directly used as a money messenger. Presumably, some soldiers will be willing to accept money tickets from all over the world, and they will be able to win over some depositors in the army. In addition, the payment of military salaries by the bank will further consolidate the credibility of the four seas and enhance the confidence of depositors. Inside and out, Sihai is equivalent to adding a lot of money turnover for nothing, and there are too many things that Qianzhuang can do. No matter how you calculate it, you won't lose money. However, without Zhang Shen's relationship, Sihai did not think of the idea of paying military salaries. This thing was boldly handed over to others, and Zhang Han couldn't rest assured.

The money bank is mainly engaged in foreign exchange, and the reputable money bank can be used as a money maker. Due to the convenience of money tickets, over time, merchants often trade directly with money tickets instead of withdrawing cash. In this way, the merchant's savings are equivalent to those of the bank. Money banks often use some of them as reserves to issue money bills, and then resell them to lend money to make profits.

In vain, the credibility of the money bank can be used as money.

Zhang Han came back to his senses in an instant, and looked at his son with a smile:

"Shen'er, you don't have any money, right? I don't have money and don't go to your grandfather, but I came to fight my idea......"

"Father's eyes are like torches......"

Zhang Shen smiled all over his face and slapped his father's ass. Grandfather was rich, and he didn't think much about it, but it was so easy.

Zhang Han's heart was happy, he laughed, and drove his son away:

"Less? Suck! If you have time to pat my ass, why don't you go see your mother...... I have to think about the military salary, and then I ......"

Although they are close relatives of father and son, it is related to the army, and Zhang Han cannot take it lightly. What will be the impact of whether Sihai Qianzhuang can take on this important task...... Zhang Han has to think about it one by one.
