Qin was not the strongest country among the six countries, what did Qin Shi Huang rely on to unify t

He relied on his strong army, as well as many excellent senior generals, and he also knew how to disperse the cohesion of the six countries, and finally unified the six countries.

Several generations of emperors of the Qin State were conscientious, and they also implemented the Shang Dynasty Reform Law and made great efforts to lay the foundation for unification. Qin Shi Huang continued to cultivate talents, so that the military strength of Qin became stronger, and finally unified the six countries.

Qin Shi Huang's ingenuity, as well as the various systems he created, were all for the good of the people, brought benefits to the people, won the hearts of the people, and naturally unified the six countries.

I think it depends on talents, because the strength of each country is about the same, and the Qin State can go ahead of other countries, mainly relying on some changes, but these changes are all proposed by talents.

Qin Shi Huang unified the six countries is a very correct approach, only when the unification will there be fewer wars, and the people will live a stable life.

During the Xia, Shang, and Zhou dynasties, China's territory was not large. The territory of the Xia Dynasty was around present-day Henan, Shandong, Shanxi, Hebei, Hubei and other places. The territory of the Shang Dynasty was about the same.

The territory of the Zhou Dynasty was the largest, reaching the Liaodong Peninsula in the northeast, southern Shaanxi in the northwest, and the Yangtze River basin in the south.

After Qin Shi Huang unified the six countries, he did not stop the pace of expanding his territory.

First of all, Qin Shi Huang sent the national captain Tu Sui to lead an army of 500,000 to the south to conquer Lingnan. In ancient times, Lingnan was the place where the Baiyue people lived, known as the land of Baiyue, which is equivalent to the whole territory of Guangdong Province, Guangxi Province, Hainan Province, and the Red River Delta of Vietnam, with an area of about 500,000 square kilometers. However, Tu Sui's military campaign was unsuccessful.

Qin Shi Huang immediately sent Ren Huan and Zhao Tuo to lead a large army to attack Lingnan, and after four years of bloody battles, they finally enclosed the Lingnan area into the territory of the Qin Dynasty.

Qin Shi Huang set up Guilin County, Nanhai County and Xiang County in Lingnan, and continued to immigrate to Lingnan Lao Natong. These immigrants from the Central Plains brought with them advanced culture and agricultural and handicraft technologies, which made the economic, social and cultural development of the relatively isolated and backward Lingnan region at that time, and gradually kept up with the rhythm of the Central Plains.

When expanding the territory to the south and north, Qin Shi Huang also opened up the five-foot road between the Central Plains and the southwest region, so that the southwest region and the Central Plains were closely linked.

If Qin Shi Huang used the system of three princes and nine secretaries and the county system to achieve the unity of the country's political system, then he also used books and texts, cars and tracks, and unified weights and measures to achieve the unity of the economic system and ideology and culture.

Carriages on the same track - During the Spring and Autumn Period and the Warring States Period, the roads between the vassal states were of different widths and sizes. After the reunification of the country, this phenomenon seriously affected the transportation exchanges between various localities and restricted economic development. Emperor Tan Shi Huang of Qin ordered the construction of three galloping roads with Xianyang as the center, one to the east, one to the south, and one to the north, which is equivalent to the current national highway.

The rails on the track are 6 feet wide. At the same time, the distance between the two wheels on the carriage was changed to 6 feet, the same as the rails on the gallop road. In this way, it is conducive to the long-distance transportation of horse-drawn carriages.

Unified weights and measures - During the Spring and Autumn Period and the Warring States Period, the weights and measures of various countries were of different sizes, which was easy to cause confusion. Qin Shi Huang implemented a unified weights and measures, in addition to the same text of the book and the same track of the car, but also implemented a unified unit of coins, length units, volume units, and weight units.

Fourth, the construction of spiritual canals.

One of the oldest canals in the world, the Ling Canal is a great hydraulic project – but it is the product of military operations.

The six states unified by Qin Shi Huang were: Qi, Chu, Yan, Korea, Zhao, and Wei.

1. Qi State: Most of the area in the north of present-day Shandong Province and the south and east of Hebei Province are close to the sea.

2. Chu State: Roughly the current Hubei Province, all of Hunan, and parts of Chongqing, Henan, Anhui, Jiangsu, Jiangxi, Shandong, Shanghai, and Zhejiang.

3. Zhao Guo: Mainly in the southern part of present-day Hebei Province, the central part of Shanxi Province and the northeast corner of Shaanxi Province.

4. Wei State: In the territory of present-day Shanxi Province, there is a southwest, and extends into the southeast. In the territory of present-day Henan Province, there is a northern part and a part of the riverside land south of the Yellow River. In the territory of present-day Hebei Province, there are present-day Daimyo and Guangping. And there is now Guanxian County, Shandong Province.

5. South Korea: It mainly includes the southwest of Jinshan and the northern part of Henan.

6. Yan Kingdom: The territory is roughly all of today's Beijing and Tianjin, and part of Hebei, Liaoning, Shanxi, Inner Mongolia and North Korea.
