The king of Qin swept the six rivers, and the tiger was powerful! Swords make clouds, and princes come to the West. ? A poem by the poet Li Bai, ancient style? "The King of Qin Sweeps Liuhe" vividly depicts the majestic power of Qin Shihuang to unify the six countries. What did Qin Shihuang achieve after unifying the whole country? Firstly, it is expounded from the political and economic aspects: politically, it has realized the five unification, strengthened the centralized rule and resisted the invasion of Xiongnu; Economically, attach importance to agriculture, build transportation and build water conservancy.

First of all, politically, Qin Shihuang realized the unification of the six countries, unified writing, unified currency, unified measurement and unified rutting. After the six countries were destroyed, the county system was adopted to strengthen centralized rule. From Lintao in the west to Liaodong in the east, the Great Wall was built to resist the Xiongnu attack. As the first king of feudal society, Qin Shihuang's achievements during his reign are of epoch-making historical significance. First, unify the six countries, end the perennial wars of separatist forces, and lay the foundation for further strengthening the rule of imperial power. The unification of writing, currency, weights and measures and ruts further promoted economic and cultural exchanges and accelerated social prosperity. Second, in the political system, the imperial power is supreme, and the prime minister and Qiu are directly responsible to the king, which constitutes the central power. Qin Shihuang adopted Lisi's suggestion and implemented the county system, with 36 counties in the local area and another county under the county. These measures effectively strengthened the rule of imperial power. Third, during the reign of Qin Shihuang, Xiongnu often harassed the border. Qin Shihuang sent Meng Tian, a general, to seize the Hetao area, open up wasteland to defend the border and build the Great Wall, which strengthened the frontier forces of Qin.

First of all, in agriculture, since the Shang Yang Reform in Qin Xiaogong, abandoned mining areas have been developed into buildings, and feudal private ownership of land has been established. After Qin Shihuang unified the six countries, the people paid taxes according to the number of fields, which improved the farmers' enthusiasm for production. Secondly, in terms of transportation, on the basis of the original six countries' chariots and horses, Qin built a chi road with uniform width, which facilitated land transportation. Thirdly, in terms of water conservancy, Qin Shihuang first sent troops to conquer the southern state of Yue, and then sent people to the local area to build Lingqu, which opened up the Yangtze River and Pearl River basins. Convenient for waterway transportation and farmland irrigation.
