The Xu Shaozhan they said about Xuan Hugong and Zhang Han is the famous Xu Guangqi in the later generations, this person was indeed a demonic existence in the late Ming Dynasty, in the early years for Xiucai to travel around to teach scriptures, in the middle of the Wanli Dynasty, after raising people, he became interested in agriculture and water conservancy, began to study astronomy and mathematics, laid a solid foundation in mathematics, Zhongjin Shihou and Matteo Ricci, a missionary from Taixilai, studied mathematics, translated geometric works, and words such as "parallel lines", "triangles", and "diagonals" and "right angles" in Chinese, Xu Guangqi took a lot of effort to translate it, even if the descendants also inherited a lot of benefits from this old man, this duke not only studied by himself, but also recruited many students in the court and the people, and at the same time encouraged missionaries to give lectures in the south hall to teach Chinese geometry and arithmetic, which is a benign development, by the time of Chongzhen, there were already quite a few scholars with a high level of arithmetic and geometry, among which the representative figure was Sun Yuanhua and others.

It can be said that Xu Guangqi's miscellaneous level is a well-deserved first person in this era!

However, among the scholars, those pedantic people were very dissatisfied with Xu Guangqi's efforts in astronomy and arithmetic, including geometry, and in the minds of the scholars, studying water conservancy and agriculture was a waste of time, and spending their energy on astronomy and geometric arithmetic was almost a plaything, and encouraging young scholars to learn these things was simply deviant.

Of course, this level of attack was only an academic dispute, and no one wanted to ban Western learning, and even had a very tolerant attitude towards missionaries whether they were preaching or lecturing, and China had not yet lost its self-confidence, which was completely different from the situation hundreds of years later.

As a student of Xu Guangqi, Kong Minxue has some grievances in his heart.

"Brother Zhizhi's academics, which part is mainly in it?"

Only then did Zhang Han understand that it was no wonder that Kong Minxing looked interested in his iron field blast furnace, it turned out to be Xu Guangqi's subordinate, if it was an ordinary scholar, I am afraid that there are really not many people who are interested in this kind of thing.

"I'm ashamed......" Kong Minxing said with a smile: "I have a strong interest in agriculture, in addition to arithmetic, if you want to talk about geometry and water conservancy or tools, although I am interested, but I don't have a deep dabble." ”

Xu Guangqi's academics are indeed too strong, and his disciples also have their own specializations, Sun Yuanhua is specialized in making weapons, and built a large number of Hongyi cannons in Dengzhou, but when Kong Youde mutinied, he coerced the Hongyi cannons and the technicians who made them, including the technicians who made fires and guns.

This Kong Minxing is good at agronomy, and he expects that Zhang Han will not have any interest in agronomy, whether it is the iron yard or the various businesses with Yusheng, all of them have nothing to do with agronomy.

Unexpectedly, after Zhang Han heard about it, he said solemnly: "Brother Zhizhi, the younger brother has something to ask, I don't know if it can be?" ”

Kong Minxing said with a smile: "What's wrong with this, let's talk together, we can talk about anything." ”

Li Shenming protested at this time and shouted: "Wen Lan, are you going to make us stay on an empty stomach all the time?" ”

Zhang Han laughed when he heard this, and hurriedly asked someone to send a table of wine and food, this is a trivial matter, it was done in an instant, while waiting, the three of them have been watching the drizzle and the surrounding scenery under the pavilion, Zhang Han's courtyard is to buy a squire's old house, decades of old mansion, the flowers and trees in the courtyard are scattered, there are some strange stones placed in the pavilion gap, the moss climbs along the mountain stone and the courtyard wall, the greenery is full, and the rain and smoke are hazy, it is actually an ordinary mansion, but people are in it, and the eyes feel particularly refreshing.

"We are all worldly people." Li Shenming spoke first: "I have been working hard all day long, and I don't know how to sit down and meditate." ”

Kong Minxing said with a smile: "If you don't make a plaster plan, how can you have this mansion to live in, and how can you have such a view?" ”

Zhang Han also said: "There are a lot of people outside who are carrying wet firewood to sell, and there are also people who pick up wontons, you say that they don't want to rest in this weather, talk and laugh with their children at home, no way, don't eat a day, Brother Zunlu, you are hypocritical." ”

"Don't you allow me to be hypocritical?" Li Shenming scolded with a smile: "You vulgar hateful. ”

Zhang Han said: "Then your vulgar cuteness is...... Well, let's sit and drink and talk. ”

These three people, Zhang Han and Li Shenming are exchange brothers, the friendship does not need to be detailed, and Kong Minxing is still meeting for the first time, but there is already a very tacit understanding between each other, the intersection of people, in fact, lies in whether the aura is integrated, of course, there are interests between each other can be exchanged, this is the basis of communication, on the basis, whether you can really establish friendship and friendship, it depends on whether each other's aura is integrated.

Fortunately for Zhang Han, he and Kong Minxing should be able to establish a preliminary friendship.

"This is chopped pepper fish head, the younger brother made it with a secret method, you two can taste it first."

Zhang Han Anran first took a pair of chopsticks, and then drank a glass of wine, the wine is not strong, soft and has a long aftertaste, which is suitable for diluting the spicy feeling in the mouth, in the eyes of Kong Minxing and Li Shenming, of course, there is nothing unusual, the fish head is mixed with green pepper and red pepper, steamed, it looks like it is colorful, making people's index fingers move, both of them are not polite, each took a big chopstick and sent it to the mouth.

"Ahem, ahem......"

"What does this taste like......

Both of them swallowed the fish meat in one bite, but this time they were guilty, Li Shenming stood up and jumped to his feet, Kong Minxing's fair face instantly turned red, Zhang Han laughed while asking the two to drink, and sure enough, after each of them had two large glasses of wine, the feeling of burning in the mouth was reduced a lot.

Li Shenming put up his brother's stand at this time and shouted: "Wen Lan, you are too mischievous. ”

Zhang Han was afraid that Kong Minxing would misunderstand, so he hurriedly explained: "This is a chili pepper, the seeds are rare, I still sent someone to Shandong to find some, left some seeds, and some took them out to entertain the two brothers, how can it be a prank...... I took a big bite myself. ”

Kong Minxing was originally a little angry, but then he understood, nodded his plate, and said, "This is from Nanyang, right?" ”

Zhang Han said: "Exactly, like corn and sweet potato, they are all passed down from the South Seas. Originally, I should have explained, but in order to leave a strong impression on the two brothers, I had to pretend to be stupid first. ”

This can be regarded as a companion, Kong Minxing and Li Shenming also laughed, the two of them picked up chopsticks again, this time they were prepared, but they felt okay, the feeling of spicy aftertaste, suddenly conquered these two people, blindly fish head, and it didn't take long to eat it up.

"What I was about to ask Brother Zhi just now is about Nanyang crops...... Zhang Han said to Kong Minxing at this time: "The chili pepper just now is a preemptive." Spicy taste, in fact, is only used to boost people's appetite, and it is impossible to use it as a staple food. However, corn this crop is very drought tolerant, the fertilizer requirements are not high, the corner of the house in front of the mountain, can be planted, and after grinding into flour, although the taste is poor, but it can also be used as a staple food, the least, with wild vegetables wintering, can make people have no hunger to death, such a good thing, how can the yield be too low, the little brother's manor also has thousands of acres of land, can be planted corn in a lot of places, there are intentions to try to plant this crop, people say that an acre of land only collects about one stone, it is better to plant some millet sorghum or beans, sweet potatoes are also this truth, the requirements for the land are not high, Not only do you not need to fertilize the field, after planting sweet potatoes for two years, the land is more fertile than before, but the yield is only lower than that of corn. ”

Kong Minxing sat still, the leisurely elegance of the scholar when he met had disappeared, and was replaced by a solemnity to the guest, which was a courtesy to Zhang Han, with Kong Minxing's status, even if Zhang Han's net worth was not expensive, in fact, there was no need to do so, this attitude only represented his personal importance to Zhang Han.

After listening to Zhang Han's question, Kong Minxing's face showed bitterness, and he hesitated for a long time before he replied solemnly: "Wenlan's question is really a big article, to be honest, it is enough to answer it in a thousand words." But here, naturally, I can't answer in such detail, I can only say that things are made because of people, and things are wasted because of people. ”

"Brother Zhi is saying that what Xuanhu Gong did in Tianjin, he will be successful, and if he is not there, it will be abolished?"

"Pretty much." Kong Minxing said: "In fact, there are many constraints, the teacher not only has to do civil affairs, but also care about the court, last year because of the incident of the Dongyu, the teacher was also awarded by the emperor to train the new army, in the past half a year, most of the energy will be focused on the training of the army, the matter of the farm, naturally abandoned, no one presides, the matter of agriculture is not favored, and no one cares, most of the efforts spent before, most of them are wasted. As for the low yield of sweet potatoes and corn mentioned by Wen Lan, the teacher has been trying to plant them all these years, and there are several problems with sweet potatoes, one is that the seeds are not easy to survive the winter, and the south is easy to plant in the north, and the land in the south is fertile, the rice yield is high, and he does not pay much attention to sweet potato planting, and only uses this kind of thing as a snack, so it is not widely planted. Second, it is necessary to select good seeds, the same as corn, after careful selection, the yield will increase by at least three percent, and then select good seeds among the good seeds of all parties, and the yield will inevitably increase greatly, but there is no court to take the lead in doing such a thing, and the strength of the teacher and I is limited, how can there be such a possibility? In fact, I have followed the teacher for many years of planting, the teacher has described some sweet potato planting improvement and yield increase methods in the book of agricultural administration, such as turning vines, cutting stems, cold bed seedlings, cutting stems breeding, seedling wintering, cellaring dry storage methods, and then can widely select good seeds, sweet potatoes are widely planted in the north or done, if you can really promote sweet potato planting along the nine borders, it is really a good thing for the benefit of the country and the people, but it is a pity that the teacher's appeal to the court and the emperor do not pay attention, it is really a pity. ”――

There is a bit of a problem with the update in the past two days, I'm really sorry, the main thing is that the cold is too heavy, groggy every day, snot constantly, four people in the family have a cold, and others have long been cured, I'm really a tragedy.
