The world of film and television starts from the flow of money

Education has received unprecedented attention among the people. Because the imperial examination has become an important way for common people to advance, every family hopes that their children can read and write.

Private schools sprang up in towns and villages, and the sound of children reading aloud could be heard everywhere. The academic atmosphere among the people was strong, and various academic groups and schools emerged one after another, exchanging ideas and learning from each other, injecting new vitality into the cultural development of Daqin.

In the military, the Qin elite still maintained a strong fighting capacity. Although it experienced the turmoil of the aristocratic rebellion, under the rectification of Yi Huawei, the Qin quickly recovered. The military merit system was still the basis for the bravery of the soldiers, and with the entry of talents from the imperial examination into the military field, new developments in strategy, tactics and equipment construction were achieved.

The Xiongnu, Western Qiang, Donghu and other places were all incorporated into the territory of Daqin, which greatly extended Daqin's border line and Daqin made new deployments in these areas.

In the northern border, facing the invasion of the remaining Xiongnu, the Qin army no longer just passively defended, but took the initiative to attack and build fortifications. A series of strong fortresses were built in the border area. At the same time, the Qin army also organized elite cavalry to carry out raids deep into the hinterland of the Western Regions, so that they dared not easily go south.

In terms of equipment construction, the development of iron smelting technology provided the Qin army with more sophisticated weapons. The Qin army's swords were sharper and their armors were stronger. At the same time, military logistics support was also strengthened, and the transportation of food and grass became more efficient. The Qin Hu Ben became famous in the surrounding areas.

After Xiqiang County accepted the exiles from the Meng, Xi and Bai tribes, the imperial court did not leave them alone.

On the one hand, control was strengthened to prevent them from rebelling again; on the other hand, they were actively guided to integrate into local life. The court sent a large number of officials and craftsmen to Xiqiang County to help develop the local economy and culture. By reclaiming farmland, developing animal husbandry, and building roads and houses, Xiqiang County gradually changed from a desolate place to a vibrant frontier area.

The same was true for Liaodong County. Although the migration of Feng Quji and Feng Jie's family caused some fluctuations in the early stage, it gradually stabilized over time. The court encouraged people from the Central Plains to migrate to Liaodong County and bring advanced agricultural technology and culture.

The Qin Dynasty's writing, laws, technology, etc. were spread to surrounding areas through envoys and merchants.

Due to the extensive cultural knowledge required by the imperial examinations, various academic studies were carried out in depth. In terms of historiography, the government organized the compilation of detailed history books of the Qin Dynasty, recording important events and figures since the founding of the country, providing valuable information for future generations to understand the history of the Qin Dynasty. Literary creation was also very active, with rich and colorful literary forms. Many excellent literary works emerged from the folk, reflecting the lives of the people.

Social order remained stable during these ten years. With the disintegration of the power of the aristocracy, public security has been greatly improved. The various conflicts caused by the aristocracy in the past have gradually decreased. The popularization of laws has also made the people more aware of the law and law-abiding. The Qin law system has been continuously improved during these ten years, with more emphasis on fairness and justice.

At the same time, the social welfare system also began to take shape. The imperial court set up orphanages, nursing homes and other welfare institutions in some wealthy areas to take care of the disadvantaged groups who had no one to rely on.

Perhaps because Confucian scholars had to undergo ten years of training (three years of study, three years of travel, and four years of living in remote counties) before they could enter the court and become officials, Confucianism did not become a prominent school of thought.

The development of science and technology is like riding a rocket because of Yilan.

In the past decade, the introduction of high-yield crops such as corn, sweet potatoes, and potatoes has changed the agricultural landscape of Daqin, and with the passage of time, agricultural technology has further developed on this basis. First of all, the irrigation technology has been deepened, and the new irrigation system is no longer limited to simple channel water diversion.

Junior engineers trained by Yilan independently designed a more complex and efficient waterwheel irrigation system. These waterwheels can not only use the water power of the river to operate automatically, but also can be assisted by animal or human power to achieve large-scale irrigation, greatly improving irrigation efficiency, so that even highland farmland far away from water sources can get sufficient water.

At the same time, agricultural tools also saw innovation. Based on the improvement of iron smelting technology, blacksmiths created a tougher and more durable iron plow. The shape of the plowshare of this new iron plow was carefully designed, which could plow the land more deeply and make the soil finer, which was conducive to the growth of crop roots. In addition, new types of manual seed drills and manual harvesters were also invented.

The seeder can sow seeds at a certain spacing and depth to ensure even distribution of seeds and improve germination rate; the harvester uses simple mechanical principles to quickly harvest mature crops, saving a lot of manpower and time.

In terms of agricultural fertilizers, students and teachers of the College of Agriculture began to study the effects of different types of fertilizers on crop yields. In addition to traditional farmyard manure, some special minerals and animal and plant residues can also produce good fertilizer effects when mixed. As a result, special fertilizer workshops were established in some agriculturally developed areas. These workshops collected raw materials and made fertilizers according to scientific formulas and supplied them to surrounding farmers, further increasing crop yields.

As an important pillar of Daqin's industry, the iron smelting industry has made significant breakthroughs in this decade. New blast furnaces were designed, which can better control the furnace temperature and improve the reduction efficiency of iron ore. The molten iron smelted by this blast furnace is of higher quality and has fewer impurities. At the same time, in order to meet the military and civilian needs for different qualities of iron products, craftsmen have mastered the basic principles of steelmaking technology and are able to produce steel with higher hardness and toughness. These steels are widely used in the manufacture of weapons, agricultural tools, and building materials.

The textile industry was not far behind. Textile machinery was improved, from simple hand-cranked spinning wheels to pedal-operated spinning wheels, which improved the efficiency of spinning. Moreover, in terms of dyeing technology, Daqin's craftsmen developed more vivid and long-lasting colors through research on different plant and mineral dyes. This made Daqin's silk and cotton cloth more competitive in the international market, and its colorful textiles became the object of competition among nobles from all countries. The construction industry has undergone earth-shaking changes. Yilan "invented" a new building material - cement.

Buildings built with cement are stronger and can withstand stronger natural disasters. Large palaces, city walls and bridges began to use cement as the main building material, and some of the iconic buildings became symbols of the technological strength of the Qin Dynasty. For example, a river-crossing bridge built near the capital Xianyang is more than one mile long. The bridge foundation is made of solid cement and boulders, and the bridge body adopts a new type of wood structure combined with cement. It can carry a large number of pedestrians and vehicles, greatly facilitating transportation.

In terms of land transportation, Daqin built roads on a large scale across the country. These roads are no longer the simple dirt roads of the past, but have adopted a multi-layer structure. The bottom layer is compacted earth and stone, the middle layer is a mixture of gravel and sand to increase the stability of the road, and the top layer is a hard road surface paved with cement. This kind of road is not only flat and wide, but also able to withstand long-term trampling by carriages and horses. In order to improve transportation efficiency, the design of the carriage has also been improved. The wheels of the new carriages use stronger wood and iron hubs, and the axles have also been reinforced, allowing the carriages to carry heavier cargo and travel faster.

In terms of water transportation, Daqin's shipbuilding technology has made a qualitative leap. Drawing on the shipbuilding experience of fishermen in coastal areas and combining new wood processing and connection technologies, larger and stronger ships were built. The hulls of these ships are made of multi-layer wooden boards and sealed with iron nails and tung oil, which have good waterproof properties. At the same time, the ships are equipped with advanced sail systems that can adjust the angle of the sails according to different wind directions to increase sailing speed.

The merchant fleet of the Qin Dynasty was thus able to sail to further places. In addition, in order to improve the conditions of inland waterway navigation, the Qin Dynasty dredged and rectified some important rivers and built water conservancy facilities such as locks, so that ships could smoothly pass through areas with large water level differences.

Military technology has always been one of the key areas of development for the Qin Dynasty. In terms of weapon manufacturing, in addition to the high-quality steel mentioned above for swords and armor, crossbow technology has also made new breakthroughs. The new crossbow has a longer range, higher accuracy, and faster loading speed. The crossbow arrows are also better made, with special shapes and materials for stronger penetration.

In terms of military communications, the Qin Dynasty established an efficient communication network based on beacon towers and post stations. The layout of beacon towers was more scientific and reasonable. They were not only widely distributed in border areas, but also set up in important strategic locations and transportation routes in the country. The transmission signals of beacon fires were more complex and diverse. Different combinations of beacon fires could convey different information, such as the number and direction of enemy troops. Post stations were equipped with well-trained postmen and fast horses, which could quickly deliver important intelligence to the court and military commanders in various places.

The medical field has also made new developments in the past decade. Under the guidance of Yi Huawei, doctors in Daqin began to conduct more in-depth research on the structure of the human body and the mechanism of disease, providing an important theoretical basis for the development of surgical operations. At the same time, doctors have also achieved some results in drug research. They systematically classified and experimented with Daqin's native herbs and discovered some new medicinal values.

In addition, there were innovations in medical instruments. Simple surgical instruments such as scalpels and tweezers were manufactured. Although these instruments were still relatively crude, they were able to meet some basic surgical needs. Moreover, Daqin also established some special medical clinics, which not only provided medical services to the people, but also became a place for doctors to exchange academic knowledge and train apprentices, laying a talent foundation for the further development of Daqin's medical technology.

The astronomical calendar also made important progress during this decade. The astronomers of the Qin Dynasty improved the accuracy of astronomical observations by improving astronomical observation instruments, such as the armillary sphere and the gnomon. They had a deeper understanding of the laws of celestial motion and were able to more accurately predict astronomical phenomena such as solar and lunar eclipses. Based on these observations, the calendar of the Qin Dynasty was further improved. The new calendar was more in line with the needs of seasonal changes and agricultural production, providing more accurate guidance for farmers to arrange their agricultural activities.

Mathematics, as the foundation of scientific research, also made great progress during this period. In the process of calculating practical problems such as land area, grain output, and engineering materials, the mathematicians of Daqin developed some new calculation methods and mathematical theories. They had a deeper study of the properties of geometric figures and were able to solve some complex geometric problems. These mathematical achievements were widely used in various fields such as architecture, agriculture, and commerce, providing important theoretical support for the development of science and technology in Daqin.

In order to ensure the sustainable development of science and technology, Yi Huawei increased the emphasis on scientific and technological knowledge in the education system. Courses related to agriculture, industry, astronomy, medicine, etc. were opened in both official and private schools. Scholars were encouraged to write science and technology textbooks, which detailed various scientific and technological knowledge and technical principles and were equipped with a large number of illustrations and examples to facilitate students' learning. At the same time, in order to encourage scientific and technological innovation, the court established special awards to give generous rewards, including money, official positions and honorary titles, to individuals or groups who made major scientific and technological inventions and discoveries.

In terms of technological inheritance, each industry has established its own master-apprentice inheritance system. The old masters imparted their skills and experience to young apprentices without reservation, and encouraged the apprentices to innovate in practice. In addition, the court also organized exchanges between craftsmen and scholars from different regions and industries, which promoted the dissemination and integration of scientific and technological knowledge across the country, laying a solid foundation for the further development of Daqin technology.

The development of science and technology has profoundly changed the social structure and people's lifestyles in Daqin. Driven by agricultural technology, the rural population has further increased, and some originally poor areas have become wealthy due to agricultural harvests. The living standards of farmers have been significantly improved, and they have more food and wealth to improve their living conditions, educate their children, etc.

At the same time, with the development of industry and commerce, the scale of cities continued to expand, and emerging industrial cities and commercial cities became places that people yearned for. More job opportunities appeared in cities, attracting a large number of rural population to influx, forming a prosperous urban economy.

In terms of culture, the development of science and technology has enriched the cultural connotation of the Qin Dynasty. Various scientific and technological inventions and innovations have become the subject of literature, painting and other art forms, and artists have used their works to show the charm of Qin's science and technology. Moreover, the spread of scientific and technological knowledge has also allowed the people to no longer be limited to traditional concepts and begin to pursue scientific knowledge and innovative spirit.

In terms of social class, the status of scientific and technological talents gradually improved. They were no longer regarded as lowly craftsmen, but were respected and recognized by society. Many scientific and technological talents became officials of the court or local celebrities through their own efforts, setting an example for the development of science and technology in Daqin.

These ten years are the golden period of Daqin's technological development. Although it is still in the foundation-laying stage of technological development, it has laid a solid technological foundation for Daqin's future development.
