Yang Xu's charter was quickly submitted.

Renamed Yang Wu as the king of Qi, Zhen Guanggu, Yang Hong as the king of Huai, Zhen Huaibei, Yang Hui as the acting king, Zhen Dai County, all three of them all ate 5,000 households, Yang Wu Yang Hong guarded 500 armor soldiers, Yang Hui guarded 1,000 fine horses.

The other princes were too young to be divided, so they stayed in Daxing for the time being.

Without the emperor's edict, he was not allowed to leave the fiefdom without reason, nor was he allowed to return to Beijing without authorization.

In Yang Xu's design, the power of a prince is equivalent to that of a county taishou.

The feudal kings of the border areas focus on governing the army and guarding the borders, while the feudal kings of the inland focus on governing the people and can also supervise the localities.

The power of the prince is not eternal, and it will be affected by the decree of Tui'en, and if he has several sons, he will divide the food into as many shares.

Their next generation can take the imperial examination, can be in the army, can enter the ranks, and do their best.

However, they were also very strictly controlled, listing 12 felonies, 27 minor sins, and the worst of which was to be punished by death, or degraded to commoners, expelled from the clan, exiled to the frontiers, and the lightest was to cut down on the food estates.

The regulations are very detailed, and even the residences, clothing, and cars of the prince, heir, and prince have strict regulations, which cannot be overcome.

Such a detailed thing is obviously not the result of him alone.

In addition to Zhang Jun, Wen Ji, Beigong Chun and others selected by Yang Zheng, there is also a group of staff members around the prince.

Although the king is bound by the imperial court, he has a certain amount of real power, and he will not sit big, nor will he be kept in captivity like Cao Wei and have nothing to do.

In addition to these, Yang Xu also imitated the ancestor of the Han Dynasty, who was not the king of the Yang family, and the world attacked him!

If Cao Wei had imitated the Han system, he would not have been exploited by the Sima family.

The Sima family was overkill, and the clan was sealed, and it was only thirty years before and after, and the Eight Kings Rebellion came out.

Yang Xu's charter is just right, and the clan has a certain amount of power in its hands, but it will not pose a threat to the center.

Yang Zheng looked at it carefully twice and felt that there was no big problem, so he handed it to Zhongshutai, Shizhong Temple, and Shangshutai to go through the process, and if there was any unreasonableness, they would pick it out.

Since the establishment of Zhongshutai, Shizhong Temple, Shangshutai, as well as the six departments of officials, households, rites, soldiers, criminals, and workers, the upper structure of Daqin has become more and more perfect, the division of labor among various official positions is clear, and the efficiency has been greatly improved compared with before.

It also lightened the burden on the emperor and allowed him to spend his mind elsewhere.

The new dynasty naturally has a new atmosphere, and all civil and military officials are hard-working.

In addition, Yang Zheng has always been right about things and not people, and his promotion depends on his political performance, so that the officials can work hard and practically, instead of putting all their minds on infighting.

The greatest advantage of doing nothing is that it creates a relaxed political environment.

If the government and governance are relaxed, the culture will also be relaxed.

Cao Wei had three Cao and seven sons, and his cultural level developed to a peak.

However, the Sima family has no bottom line, and the upright scholars have avoided the world and rejected the Sima family's conquest, and the wind of pure talk and metaphysics has become more and more intense, divorced from reality, and the clean talk has become empty talk, and the social atmosphere is unprecedentedly impetuous, and there are people who sell their fame and reputation everywhere.

In fact, various academics were very active in the Wei and Jin dynasties.

It was during this period that Buddhism was combined with Chinese civilization, especially Dunhuang and Guzang.

Taoism also gradually appeared on the stage of history at this time, from the Taiping Dao to the Wudou Mijiao, and evolved into the Heavenly Master Dao.

Ma Jun, Liu Hui, Huangfu Mi, Pei Xiu, Zu Chongzhi, Li Daoyuan, Ge Hong, etc., mechanical, medical, geography, astronomy, mathematics, hydrology, chemistry, etc., have quite high achievements.

And the Confucianism of this era did not rest on its laurels, there was a certain progressive significance, many scholars were more omnipotent, Ji Kang, Du Pre, Wei Xuan, Suo Jing, Pei Xiu, Zhang Hua, etc., were not powerless sour scholars.

As long as the Jin Dynasty of the Sima family is not too stretched, the Chinese civilization will enter a new stage four hundred years in advance.

It's a pity that the Sima family not only pulled their hips, but also......

"Your Majesty, the children of Qingying found excellent rice seeds in Jiaozhou last year, and this year's trial planting was successful, and the yield per mu increased by one percent!" Zhao Aqi excitedly came in with a small sack of rice.

"Oh?" Yang Zheng was overjoyed.

After so many years of investment, I finally see the results.

In this era, according to the records of the "Historical Records, River Canal Book" and "Food and Goods Chronicle", one mu can produce three stones, eight buckets and four liters of millet, that is, about two hundred and eighty-one catties of corn in later generations, and two and a half stones of rice per mu of rice in the south.

An increase of one percent may not seem like much, but it cannot stand the large base of the country.

And it's a good start.

If we want to increase the population, one is to increase grain production, and the other is to lightly reduce the income.

The two are actually interconnected, reducing their survival pressure, survival pressure is high, running around for a livelihood every day, they can't support themselves, how can they still be in the mood to have a baby?

In fact, Yang Zheng personally doesn't like to eat corn very much, the taste is not as good as wheat and rice, and the main thing is to boil porridge.

However, the yield of corn is high, it can be stored for nine years, rice and wheat for up to five years, and corn is also an excellent feed for war horses, so it has become the mainstream in the north.

The guards opened the sack and inspected it before presenting it to Yang Zheng.

The rice is more slender than that of later generations, but it is not as full as that of later generations.

This may be due to the absence of various chemical fertilizers.

"Extensive farming in the south, if it is intensive, the yield will increase again." Loose cavalry often serves Wang Jundao.

"Shiji also knows about farming?" Yang Zheng has never been to the south, and the southernmost place he has been to is Hanzhong.

However, Wang Jun's words opened up an idea for Yang Zheng to improve yield, excellent rice seeds are one thing, cultivation technology is also one thing, and the other is the improvement of farming tools.

The Quyuan plough and composting method in Guanzhong have not yet been extended to the whole country, and many places still use stone ploughs and wooden ploughs.

"There are many descriptions in classics such as the Book of Poetry, Guanzi, and the Four People's Moon Order, and the minister traveled to Jingxiang in his early years, so he knows one or two." From any point of view, Wang Jun is a real scholar, who can go into battle, understand history, and govern one side.

Yang Zheng secretly thought in his heart, Yizhou Thorn History is Zhang Fu, his strength is to fight Haoqiang, not afraid of power, in Shuzhong for so many years, Haoqiang was subdued by him, a large number of scholars Haoqiang in order to avoid him, took the initiative to move to Nanzhong, these people to Nanzhong, enslaved the local natives, enclosed land and robbed people, and the local natives cut each other, busy and happy, but became the pioneer of the development of Nanzhong.

In the four or five years of Shuzhong's great governance, the population has increased by more than 400,000!

In addition to the people born and raised, there are also Ba Yi and other ethnic groups who go down to the mountains for the people, and the Qiang people on the plateau are attached.

Zhang Fu's political achievements in recent years have surpassed Yang Huan and Yang Jun, ranking first.

It is not suitable for this kind of talent to stay in Shuzhong, and according to the regulations of Great Qin, Zhang Fu should either be transferred to the center and be a Shangshu, or he should be appointed elsewhere.

It just so happened that the Central Plains was in the bag, and although the Shandong Shi clan Haoqiang was shaved a wave, he still had a lot of strength, and he needed someone like Zhang Fu to cure it.

To govern the country is to make the best use of people.

"I promoted you to the history of Yizhou, save grain and grass, build a warship, and prepare for the war of Wu!"

"Commanded!"

Wang Jun is the history of the Yizhou assassin, and Zhang Fu is the history of the Qingzhou assassin, ready to take over Wei Xuan.

The dock fort in the Central Plains was almost demolished, and there was no need to leave Daqin's Shangshu Order there.
