"Really, duckweed also has rhizomes and leaves, but the stems are degenerate." Lizhi smiled like a flower, nesting in Zhang Chun's arms and looking at the duckweed in his hand.

"There's degradation, there's evolution, you see they have air sacs in their leaves and rhizomes, and they can float on the water. You see it's just one kind, you see there's duckweed over there, the rhizomes are very light, they have to take root in the mud, so they have to grow very long. Because they are rich in nutrients, the leaves can grow very large. You can't do it in your hand, it's thin and small. Duckweed is a family because it looks somewhat like Araceae, and they can also be seen as a species of the order Araceae, monocotyledons, angiosperms. These plants are related to each other, but they are only close and far. Zhang Chun and Lizhi were face to face.

"Brother Tian, they're going to do this?" Lizhi rubbed it very comfortably.

"They should have noticed this, there are more rice fields, the soil of the rice fields is often ploughed, and the root system of the rice is also very developed, and other duckweed can't grab it, but you can't grab it in your hand. As long as there are enough nutrients in the water, they will multiply quickly. Brother Tian, if they want to figure out the plant environment of the rice field, they need to figure this out. ”

"Do they work, do they?"

"Yes, they grow fast and fix nutrients in the air very quickly, when the water in the paddy fields is drained, there is no water, they die, rot, and the fixed nutrients will increase the fertility of the paddy fields. Therefore, it is important to manage the water, fertilizer, and environment of the paddy field. ”

Yuan Fang, who looked at the little ones frolicking in the water with a smile, said with a smile: "Duckweed is a good medicine to get rid of dampness and heat, you are still young, and you will know it when you grow up and study medicine." ”

Yuan Fang is not worried about the children playing in the water, more than a dozen of the children are landlubbers from Henan, fortunately, this shallow beach is not deep, and there are local ghosts who grow up in the water all day long, so it is not dangerous.

"Oh." Lizhi replied casually, this girl is smart, but she hasn't been qualitative, she asks everything, and she agrees to everything. But in fact, I still don't understand it.

Yuan Fang is no longer surprised that the six-year-old child knows so much, because these two children always see what they learn in this way. If you don't understand, Zhang Chun will go to the book by himself, and he will observe and summarize. This is where Zhang Chun is powerful.

In May, Pastor Julian returned to Yunlong Town.

He brought a big trouble to Zhangjialing or the Yunlong Wu family.

After the third young master of the Wu family of Yunlong was broken in his leg by the troublesome peasants, he went to the foreign doctor in Hankou for surgery, but the effect was not very good. The Wu family asked Julian to treat his illness, but Julian brought the third young master of the Wu family to Zhangjialing, there was no way, only Zhangjialing had a qualified operating room, and except for Zhang Xiu, Julian could not find a qualified nurse.

The operation was very successful, but because the health center was full of girls, in the eyes of the third young master of the Wu family, they were all Zhang Chun's maids and maids. And these girls are all sixteen or seventeen years old, far more beautiful than the girls outside. After a few days, Wu Sangongzi began to move his hands and feet. As a result, he was driven back by Yuan Fang, and charged a hundred taels of silver for treatment, which was higher than the foreign doctor's fee in Hankou. was so angry that the Wu family swore not to come to Yuan Fang for treatment.

But Julian also got angry and didn't help him with a follow-up. The muscles and bones were injured for three months, because Wu Jiasanshao had the second operation, and the recovery was slow. The third young master was a restless master again, and his injuries recurred. But Yuan Fang, who was protecting the cubs, and the Wu family completely fell out. The third young grandmother of the Wu family came to invite her in person, and Yuan Fang sent her back.

After tossing for a while, the Wu family had no choice, and the old lady came to beg Zhang Chun in person, which was quite pitiful. For the sake of the old lady's old age, Zhang Chun came forward to reconcile, and Julian took Wu Sangongzi to the church and locked him up for two months.

Old man Julian was also surprised by the changes in Zhangjialing Mengxue, and resumed the habit of riding a donkey back and forth every day.

Julian gave each child a physical examination at the health center, and praised Zhang Xiu's mass prevention and treatment and public sanitation work. Julian often wears a long robe and a horse coat, and if it weren't for his white skin, yellow hair and blue eyes, you would have thought he was an old Chinese man. Julian was in his fifties, and Europeans seemed to age quickly, and with a full beard, one thought he was sixty or seventy years old. Because this old man is diligent and speaks Chinese quite slipperily. He is often pulled by Zhang Chun to give lectures to children, so he is very popular with children. Often Zhang Chun just said bad things about him, and it was immediately spread to his ears by the children. The old man yelled every day to find Zhang Chun's theory.

Julian didn't come alone this time, he also brought five white-skinned, male-eyed children between the ages of four and eight. And these children don't speak the same language, it turns out that South Africa was the Boer War between Britain and the Netherlands for a colony. These children were war orphans of the Boer War, French, Portuguese, Dutch, and British children. Germany was neutral in the Boer War, so the orphans adopted by the church were brought to China by Julian.

The five children, all girls, were changed by Julian to Chinese names, all with the surname Zhu. Originally, he was going to be educated in a church school in Hankou, but Julian felt that Zhang Chun was very good here, and there was no rejection of Julian as a foreigner, so he directly brought these five children over.

Five dolls were placed in each grade to read with everyone, and soon they mingled. Because the teachers, including Hu Dengping, often explain world geography, and Julian also talks about the history of some countries around the world, all the children in Mengxue Hall do not think that the dolls are anything special, but because many of them are orphans, they take special care of the five little girls.

Julian loved the atmosphere of the school.

But I always feel that Zhang Chun is an unteachable person, and I often stare at Zhang Chun by blowing his beard. This is something that no one else dares to do.

Zhang Chun also found it interesting to tease this rigid and stubborn old man, so he buried this foreign devil in and out of class. Zhang Chun also deliberately observed how the five dolls reacted, and found that the five dolls smiled more happily than the Chinese children.

Julian had the unique German sense of admitting death and earnestness, which was not very dissatisfied with Zhang Chun's insistence on using backward earthen looms, and directly called the door to "theoretical", but in fact he was "coldly treated" by Zhang Chun and Lizhen.

Still Julian was used to it, and he sat quietly at the table. While drinking the dragon well he brought, he watched Lizhi carefully eat peaches. In front of him, in addition to a plate of peaches, there was also a plate of apricots. It was just sent by someone from Henan Village.

"Mister Chun, why not use an advanced loom, know that it is a revolution, fast and good. Don't tell me that you don't have any money, you spent a thousand taels of silver to buy the Wu family's land. You also bought a generator and a lot of medical equipment, which is much more expensive than a loom. Julian was very unhappy with the old loom.

Zhang Chun peeled the peaches for Lizhi. Without raising his head, he said: "Julian, this kind of peach is very delicious, you don't just drink tea, eat one." ”

Julian shook his head: "I'm full, I've already eaten a few, and I can't eat anymore." ”

Zhang Chun said with a smile: "That's right, my aunt and they weave enough cloth for everyone to wear, so there is no need to change the loom for the time being." You know I have a lot of people here, everybody has to work, and if I don't work, my aunt doesn't know what to say about me. And they're used to it, it's their life. ”

"You don't want to make money?" Julian asked, surprised.

"Who said I don't want to make money, I'm poor to death, and I don't have any money in my hand."

Julian smiled: "It would be nice to change the loom, you can weave a lot of cloth and earn a lot of silver." ”

Zhang Chun shook his head: "The loom has to be replaced." But I have to make sure that my aunts have something to do and that they are doing well. Cotton is needed for weaving, and the yield of cotton here is too low to be enough. Increasing the planting area is not suitable now. ”

"You can buy cotton, and the profit in the middle is very large."

"I don't have enough here, and it's the same outside, we have to increase the area of cotton planting, and if there is more cotton, there will be less food, and many people will starve to death. Do you know how many people starved to death from the drought last year? It is caused by the expansion of the cotton area. China is different from your Germany, if you look at me here, there is a lot of land of more than 3,000 acres, but I have hundreds of people here, and the per capita land is not enough, and people will really starve to death. ”

"You really have a little more people here, but they are all your servants, you don't need to be so nice to them." Julian said casually, but found that Zhang Chun was glaring at him, and quickly changed his words: "You can't reject advanced technology for this reason." ”

Zhang Chun smiled: "I did not reject advanced technology, but everything must have a reasonable basis, and if the cotton yield increases, the loom will naturally be replaced." However, the new loom is machine-driven, and it is not only a problem with cotton. There will be other problems, such as pollution, your oil is polluted, at least I can't make farm manure. Maybe I won't be able to survive the fish in the pond, and there will be problems with the yield of the rice fields. In general, there are also problems such as steel, coal, and so on. No pollution occurs in steel manufacturing? Same. So it's a system problem, you know the system problem? ”

Julian's face was confused: "Mister Chun, your theory is not right, industry and commerce have their own laws, they will give birth to science and technology, bring huge profits, you can't exclude them, you are a conservative." ”

Zhang Chun shook his head: "I'm not conservative, I just think long-term." The bottom line is that I'm too small here, my capacity is limited, and I can't upset the balance. ”

Julian smiled: "You ignore the self-healing ability of nature, and if you zoom in a little bit, there will be no problems you say, and the great Germany, the first in the industrial world, will not appear the problems you say, the same mountains and rivers are beautiful." ”

"How many people are there in your country? Don't talk about that, you must know that I said that your Western medicine is a low-level medical thing. You know why? ”

"I know, there's some truth to what you're saying."

"You don't know, do you know how to treat appendicitis?"

"It is often inflamed, and it can be surgically removed, and it does not do much harm to the human body."

"Haha, I know that this is the problem of your Western medicine, you don't understand the system problem. The appendix is the trachea that digests crude fiber, and herbivores are well developed. In fact, it is a very important part of the body's immune system, it is very sensitive to foreign substances entering the stomach and intestines, directs the stomach and intestines to speed up digestion, and at the same time gives the body the ability to resist some toxins. In the theory of traditional Chinese medicine, it is a part of the function of guarding qi, it is easy to become inflamed, but it is also inflamed to resist external evils. The most important thing is that a large part of the reason for his inflammation is because the human body does not supply it with blood and nutrients, and it cannot resist external evils, so it can only die. This means that there is a problem with the body's nutrient supply system. Traditional Chinese medicine treatment can reduce the invasion of external evils through taboos, invigorate qi and blood, and improve the body's nutrient supply. Not only does the appendix not need to be removed, but it is also fully functional. Unless it's completely necrotic and can't be used. That's why I say that your Western medicine is a low-level medical skill. ”

"Mister Chun, what you said is not so clear in your Chinese medicine books, you can't prove that what you said is correct, although I can't refute you, but I can't agree with it." Julian is still so stubborn. This is probably the character of the Germans.

"It doesn't matter if you agree with it or not, I'm explaining this so that you can understand the system. It is a link that restricts and promotes each other to become a whole. If you break one link, the whole system will change unforeseenly. God will come and correct you, and in China it is called the Way of Heaven. The way of heaven is divided into gains and losses. Western medicine is based on the word loss, and Chinese medicine recommends the word benefit. Going back to what you said about the textile industry, if it is built on destruction and exploitation, it is wrong. But if I can increase cotton yields and keep the textile scale from above that. That's right. ”

"You're going to lose a huge amount of profit."

"There is a saying in China that a gentleman loves talent and takes it in the right way." Zhang Chun fed the peach in his hand to Lishi's mouth.

Li Zhi said: "The way of heaven is not the way of the road. ”

Zhang Chun shaved on Li's little face. "That's smart."

Lizi smiled so hard that she lost her eyes.
