Therefore, it was decided to divide the world into 36 counties until the end of the Qin Dynasty, and a total of 54 counties were placed, and each county was set up with a county guard (in charge of civil affairs), a county lieutenant (in charge of military affairs), and a county supervisor (in charge of supervision), appointed by the central court, not hereditary, and must report to the court on taxes, household registration and public security.

Qin Shi Huang decided to adopt a three-level administrative division system in local governance, and built a vertical pyramid control system of central-county-county-township-pavilion-li-shi-wu-household to strengthen local control.

Under the county, the "township pavilion system" (also known as the township system) was implemented, and "townships" were set up, and the specific methods were to set up "three elders" at the "township" level to be in charge of education, "husbands" to hear lawsuits and collect taxes, and "wandering" to detect thieves.

In addition, below the township level, the use of civil power to govern, a township jurisdiction of ten pavilions, set up a pavilion chief, a pavilion jurisdiction of ten miles, set up "Likui" (also known as Lizheng), one mile jurisdiction of a hundred, five for the family, ten for what. This system gave the Qin Dynasty great mobilization power, even though when Cyrus the Great of Persia founded the empire more than 300 years ago, the Achaemenid dynasty had only provinces (Satrapi) and counties as administrative divisions.

In addition, the Huaiyi and Siyi that had been entrenched in the Huai River valley had long since become civilian households, and after Qin Shi Huang unified the world, he set up Minzhong County in the area of present-day Fujian Province.

Because Qin Shi Huang believed that Minzhong County was far away from the Central Plains, it was a "country of deserted clothing" and was located in a remote area. The mountains were high and the roads were dangerous, and the Yue people were so strong that it was difficult to rule, so they did not actually send officials to Fujian, but only abolished the throne of the local chieftain Wuzhu and Shasha, and replaced it with the name of "Jun Chang" to let him continue to rule the place.

After the implementation of the county system throughout the country, it was marked that there would no longer be princes who supported the army and divided the territory, elected their own officials, and were financially independent. In addition, the place of origin of the people is no longer the vassal state to which they belonged. For example, the people of Chu, Qi, etc. are used as identification. Instead, it is identified by the name of the county in which it is located.

However, after Qin destroyed the Han Dynasty, Liu Bang, the ancestor of the Han Dynasty, believed that after the Qin royal family implemented the county system, it died due to the lack of clan and domain. So the county system was introduced. The children of the Liu clan were crowned kings. However, it led to the rebellion of the Seven Kingdoms of Wu and Chu in the future. Therefore, successive rulers have tried to strike a certain balance between the county system and the feudal system in order to maintain the national ancestry.

In order to prevent the remnants of the Six Nations from rebelling. Qin Shi Huang ordered to collect the world's weapons, gather them in Xianyang and melt them, cast them into a big bell and twelve bronze figures, each weighing 240,000 catties, and placed them in the court.

In 215 B.C. (the 32nd year of Qin Shi Huang), Qin Shi Huang carried out the second parade, passing through Jieshi, announcing the demolition of the original city outline and embankment built by the six countries of the Kanto region, called "falling city outline, breaking embankment, and destroying danger obstacles", and carved a stone monument at the Jieshi Mountain Gate, the inscription is as follows:

"Then the division and brigade were revived, and there was no way to kill, and they were destroyed for the reverse. The martial arts are violent and rebellious, Wen Fu is not guilty, and he is obedient. Benefit on merit, reward cattle and horses, and enrich the soil area.

Emperor Fenwei, the princes of De, the first Taiping. Corrupt the city, break through the Sichuan defense, and raze the danger. The terrain is established, Li Shu has no rope, and the world is salty.

Men enjoy their domains, women cultivate their careers, and everything is orderly. Hui was all produced, and he came to the field for a long time, so he was not disturbed. The ministers recite the martyrs, please engrave this stone, and hang the etiquette.

Translation: The emperor raised troops and used troops to destroy the unrighteous king, and to put down the rebellion. Eliminate the rioters by force, rehabilitate the good people in accordance with the law, and the will of the people will be submissive. On meritorious deeds to reward the ministers, benefit Ze Shi and cattle and horses, the emperor's grace is all over the country.

The emperor was invigorated by his might, and the princes were annexed with virtue, and the world was unified and peaceful. Demolish the old castle of Kanto, dig up river embankments, and raze obstacles. Now that the terrain has been flattened, and the people are not subject to servitude, the whole world must be pacified.

Men are happy to farm, women are red, and everything is in order. The emperor's grace covers all industries, and they work diligently to cultivate the fields, and they are all happy to live in peace. The ministers salute the great cause, please engrave this stone, and leave the model rules forever. - "Historical Records of Qin Shi Huang Benji"

As for the demolition of the embankments built by the former six Kwantung countries, the reason was to eliminate local divisions, and this was due to the irrational design of the embankments in each country. According to the records of Mencius's Confessions, Bai Gui, a famous water conservancy expert and businessman of Wei, once pointed out to Mencius that his level of flood control was better than that of Dayu, but Mencius did not think so, accusing Bai Gui of only using his neighbors as a gully to store water, that is, leading floods to other countries, which made the people disgusted.

In addition, according to the records of the Hanshu Gou Xun Zhi, at that time the two countries of Qi and Zhao Wei were bounded by the Yellow River, and the two countries of Zhao and Wei were located in the upper reaches of the Yellow River, with higher terrain, and the terrain of Qi was low, and when the Yellow River flooded, the disaster suffered by Qi was more serious, so Qi first built an embankment 25 miles away from the Yellow River along the Yellow River to prevent the flooding of the Yellow River.

Since the Qi state built an embankment along the Yellow River, causing the overflowing water of the Yellow River to rush towards the Zhao and Wei countries, the Zhao and Wei countries also built an embankment along the Yellow River 25 miles from the river. From the above records, it can be seen that the princes of the Warring States used water conservancy facilities as a means to weaken the enemy state, so Qin Shi Huang emphasized the adoption of measures to "break through the defense of the river".

In addition to preventing the remnants of the Six Nations from causing chaos, measures such as "falling down the city, bursting the embankment, and destroying the danger" also played a role in facilitating transportation and promoting trade.

After the destruction of the Six Kingdoms, Qin Shi Huang ordered the relocation of 120,000 wealthy families from the Six Kingdoms of the Kwantung region to Xianyang, among which the wealthy from Qi and Chu were the mainstays. This is because the land of Qilu advocates "Qilu Studies", advocates gathering people to give lectures, and pursues elegance, which is completely different from the mainstream thought of the Qin State "Three Jin Studies", which advocates seeking prosperity and strength, still utilitarianism, and pragmatism.

However, compared with the Qi State, Qin Shi Huang was more worried about the hometown of the Chu State, for example, during his inspection of the hometown of the Chu State, the historical records can be seen in the records of his digging in Jinling, Dantu, Qu'a and other places in Jiangdong to dislike the spirit of the heavens, and the saying "the death of Qin will be Chu" also reflects the strong desire of the Chu people for revenge. Therefore, it became natural that the migrants should be the master of the land of Qichu.

On the other hand, the relocation of the rich had other political intentions, in addition to prospering the capital, and also to avoid collusion between the rich and the nobles of the six countries. In addition, the local instability caused by the local annexation of land by the wealthy and usurious loans, and the migration of them to Xianyang also helped to eliminate local tensions.

After Qin Shi Huang unified the world, he learned that the scripts of the six countries were different, and decided to implement the policy of "writing the same text", according to Li Si, who was the court lieutenant at the time, abolished the original script of the six countries of Kwantung, and simplified the large seal of the history to the small seal (also known as the Qin seal), as the common font of the whole country Fifteen articles, but now the world calls Li Si the originator of the small seal, and its legendary books have "Mount Tai carved stone", "Langya Tai carved stone", "Lingshan carved stone" and "Huiji carved stone" and so on.

During the Western Han Dynasty, the calligrapher merged the three chapters with six crosses into the Cangshou Chapter, with a total of 55 chapters. During the Western Han Dynasty, it was also called "Cangqiu", "Zhan History", and "Erudition" as the three cangs, but for a variety of reasons, most of the texts of the "Cangqi Chapter" were lost.

On the other hand, according to the book "Shu Xuan" written by Zhang Huaiqian of the Tang Dynasty, Cheng Miao (character Yuan Cen), a native of Xiatai (present-day Weinan City, Shaanxi Province) of the Qin Dynasty, spent ten years in prison to create official scripts, which were appreciated by Qin Shi Huang and appointed as the imperial historian.

Because the small seal is difficult to use in an environment with a lot of work, the font invented by Cheng Miao is quite popular, and because the Cheng Miao font was originally used exclusively for official service, this book style is called Lishu, but there is no record of Cheng Miao's life in the official history.

Weights and measures are traditionally a general term for units of length, volume, and weight. Degrees are used to calculate length, quantities are used to measure volume, and weights are used to calculate the weight of objects. During the Warring States period, different weights and measures were used in various countries, which made the conversion process very confusing. (To be continued......)
