A few days later, when Zhang Han went to Bian Dongzhuang again to do business, he picked up Li Xiaoer by the way. Li Shengzhong was very happy, but he behaved much more decently this time. Big and small he is also a character, if it is not too much pressure, he still has a set of ways to deal with people. Now that he has become Zhang Han's confidant, he has a certain guarantee for the future. Li Shengzhong has a bottom in his heart, so he is much more natural, not to mention calm, at least he has a basis for advancing and retreating.

Zhang Han went, and it was not only Li Xiaoer who picked him up.

At the beginning, Zhang Han's plan was very good - the wisdom of the working people is endless, and with effective experimental methods, I believe that it will be very effective. However, Zhang Han ignored a practical problem - there were very few literate people in the Han Kingdom. Therefore, research methods based on experimental records and analysis of experimental records simply do not work. Only in the glazed kiln that Zhang Zhao attached great importance to, he specially sent someone to record it, and this was reluctantly implemented.

After discovering this problem, Zhang Han didn't have much to do. It is difficult for a good woman to cook without rice, and she can't do anything without a hand. But the crucible experiment needs to be recorded; For smelting technology to develop, the original record is also very crucial; The same is true for other technologies. Therefore, every time he went to Bian Dongzhuang, as long as he had time, Zhang Han would gather the children of important craftsmen, such as Li Xiaoer and Wang Jiajun, and teach them literacy and simple calculations.

Fortunately, these records are very simple, and the words used are very limited, generally speaking, it is enough to learn three or five crosses. And the opportunity to read and write is so rare, the children are told by their parents, served with sticks, they are very attentive, and after spending a little time, they can make a simple record. However, Zhang Han did not stop, he has always insisted on education, and after more than two years of intermittent work, these children have also known hundreds of words, and they can simply add, subtract, multiply, and divide.

When giving lectures, Zhang Han did not limit the number of people to observe, but encouraged the craftsmen to come and learn. In a sense, Zhang Han was also the teacher of craftsmen such as Li Shengzhong. This also greatly increased Zhang Han's prestige in the iron-smelting workshop.

Wang Guanquan himself is old and embarrassed to come, but he has been very close to his grandson Wang Jiajun's study. Wang Jiajun once secretly told Zhang Han that his grandfather was also learning literacy behind his back. Zhang Han listened and laughed.

This time, Wang Guanquan contributed a lot to the improvement of steelmaking technology, and Zhang Han treated everyone equally, and took Wang Jiajun into the family study. In the study of clans, there were originally children of important tribal families who went to school. But Wang Guanquan's steward is still a little bit worse, and Zhang Han is now recruiting his children into school, which is both a reward and a bought. However, knowing this, Wang Guanquan could not refuse either.

Walking on the road on horseback, Zhang Han found that the two boys were a little quiet today.

Zhang Han is only fifteen years old this year, only three years older than Li Xiaoer and four years older than Wang Jiajun, but he has always been mature and steady, and he is full of prestige in front of this group of children. But after a long time, the children also know that Zhang Han is usually very talkative, and he is quite close to him, so he will not be so honest. It is estimated that he was 'intimidated' by his parents.

Zhang Han pretended not to know, and casually found a topic to talk to the two novels. Li Xiaoer and Wang Jiajun are both children, and after saying a few words, they slowly forgot their family's instructions and became lively.

The two have always lived in Bian Dongzhuang and rarely go out. When Li Xiaoer fled from Runan, he was still young and didn't remember much, so he was too far away. Wang Jiajun has only been to Bian Dong County at the farthest, and he is surprised to see everything along the way. Along the way, there is no time for the mouth to stop. Zhang Han ran around all day long, and rarely had such an opportunity to walk slowly, but he had no intention of answering these children's words, so he asked Liu Wenbiao to talk to him. Liu Wenbiao is Zhang Han's shadow, wherever Zhang Han goes out, he will follow him. has had more contact, and the two are no strangers to Liu Wenbiao. Liu Wenbiao had no choice but to be patient and talk to the two children.

Bian Dongzhuang and Bian Nanzhuang are in the same county, only more than 30 miles apart, although the ox cart is slow, there is an hour, but also see Bian Nanzhuang from a distance. Da Hei walked slowly all the way, feeling quite impatient, seeing the familiar scenery, he couldn't help but get excited, snorted, "sigh, ......", hissed, and trotted two steps.

Zhang Han rarely walked quietly, and it felt just right. Patting the horse's neck and appeasing Da Hei, Zhang Han straightened his body and strolled around, browsing the scenery around. Without the destruction and pollution of industry, the mountains and rivers of Dahan are beautiful and the air is fresh, which is far from being comparable to later generations.

Having lived in Bian Nanzhuang for more than two years, Zhang Han is already familiar with this place. Coming down from the avenue, the group turned into the road of Bian Nanzhuang's self-cultivation. The roads used by the house are often repaired and are very smooth, but they are not as wide as the avenues. Bian Nanzhuang has a large number of people coming and going, but the fifteen-step wide road is enough to cope with it.

Every two steps along the road, a tree is planted. Instead of the elms, locust trees and green pines that are often planted on both sides of the avenue, deciduous oaks and ginkgo trees are planted here.

Ginkgo biloba, also known as ginkgo tree, is soaked in water with ginkgo leaves, which is very good for the health of the elderly. After Zhang Zhao tried it, he felt that the effect was good, and ginkgo tea became one of his daily drinks. Ginkgo seeds are also a very good health food, and the taste is excellent after being fried, and Zhang Zhao often drinks wine.

The young leaves of the deciduous oak can be used to feed silkworms, and the old leaves are used as fodder, and oak is an excellent quality wood, which can be used to make bows, crossbows, furniture, floors and ships. However, according to Zhang Han's meaning, he prefers cork oak, which is a cork oak after the bark is peeled off, which is cork and has many uses.

Zhang Han just thought about these thoughts in private. If Zhang Han really had to call the shots, there would only be shrubs such as lilacs and alfalfa on the hillsides, and he didn't want to plant trees outside his city to make it easier for the besiegers. However, Zhang Han can't be the master, and this can't be said on the surface.

The wheat fields on both sides of the road have been harvested, but they are not empty. The Zhang family's treatment of slaves is not bad, and when the farm is busy, the rice is full, no worse than that eaten by ordinary poor households. They did not have to pay the poll tax and all kinds of levies, and they did not have to worry about food and clothing in the event of a disaster. In a way, their lives are easier than those of the poor. However, they also have more work throughout the year. In October, when the other family's farming work is over, the Zhang family still has to plant some green beans, adzuki beans, sesame seeds and weeds in the field. These things need to be planted in the middle of the wheat in advance so that they can be harvested in November. Because sowing seeds in wheat fields can only rely on manual labor, it is very troublesome and requires a lot of labor. Therefore, many times, the Zhang family waits for the wheat to be harvested before sowing the seeds. In this way, it is naturally impossible to harvest, just turn the whole seedling into the soil, purely as fertilizer.

"What is that, sir?"

Zhang Hanzheng was fascinated, but a voice came from his ears, and when he turned his head, it turned out to be Li Xiaoer, he pointed to the other side and asked in surprise. Liu Wenbiao didn't know whether this question should be answered, and after a little hesitation, Li Xiaoer thought he didn't know, so he asked Zhang Han directly.

"Qu Yuan plow! Haven't you seen it? ”

"Qu Yuan plow, I have seen it. But I haven't seen this ......."

Li Xiaoer's voice was much quieter, but he refused to admit that it was Qu Yuan Li. It was a very strange plow, like a zigzag plow, with two boxes on its back, and some miscellaneous things in the back. A man was leading an ox and pulling the strange plow to plough the ground in a clearing.

"That's a zigzag plow, you'll know later."

Zhang Han laughed and didn't explain much. Han Laoqi is experimenting again, and I don't know if he has made progress.

In terms of farm tools, Zhang Han did not waste his thoughts. Limited to conditions, mechanized agricultural machinery is definitely not used. It can be used as a reference for the old-fashioned farm tools he used when he was a child. Zhang Han relied on his memory to sketch farm tools such as quyuan plows.

The iron ploughshare of the Han Kingdom is very common, it is a kind of straight plough without a bed, that is, two oxen carry a plough together, including a plough wheel, a plough tip, a plough bottom, a ploughshare and a plough wall, which is very heavy and inconvenient to turn. However, in the Kanto region (referring to the east of Hangu Pass), a kind of cocoon plow, that is, a three-legged cocoon, can complete the task of ditching, planting, and covering at one time.

In the reclamation of wasteland, the simple version of the curved plough is well received, but the cultivation efficiency is not as good as the plow, so naturally it is not possible to talk about the popularization and application. Daily farming, the Zhang family used, or the plow, until a large number of reclamation in recent years, Quyuan plough used more.
