Qin Shihuang's merits and demerits?

First, Qin Shihuang's achievements: In the central government, three posts and nine departments were implemented to manage state affairs. The enfeoffment system was abolished at the local level and replaced by the county system. At the same time, books are written in the same language and cars are on the same track. Unified measurement. Attacking Xiongnu in the north, conquering Baiyue in the south, building the Great Wall of Wan Li, building Lingqu and connecting the water system.

1, Qin Shihuang implemented the county system, which made China truly unified. The greatest civilized achievement of the county system is the complete abolition of the so-called hereditary aristocratic system, which has created a new and fairer way for the emergence of nobles.

2. Qin Shihuang realized the unification of writing and weights and measures, which greatly strengthened the cultural integration and economic exchange and development among all ethnic groups. For more than two thousand years, no matter how far apart, from a few kilometers to thousands of kilometers, people in different regions have different living habits and languages, but as long as they are literate, they can achieve barrier-free communication. All this is due to the unified writing of Qin Shihuang.

Qin Shihuang built a straight road all over the country, which opened the way for human beings to build expressways. Besides straightening roads, Qin Shihuang also dug canals to connect the Yangtze River and the Pearl River. After a short trip to the frontier, the territory of China was basically laid.

Second, Qin Shihuang's experience: seeking immortality, harming the people, killing the people's wisdom and shaking the foundation of Qin Dynasty's rule.

Burn books and bury Confucianism. Burning books and burying Confucianism is an extremely cruel event in the history of China: a large number of ancient books and documents in the pre-Qin period were set on fire, which caused great losses to China culture; Since the end of the Spring and Autumn Period, the flourishing spirit of free thought has been dealt a fatal blow. Set a bad example for later generations to implement the policy of cultural autocracy.

Extended data:

Qin Shihuang's establishment of the Chinese Empire is unparalleled, and his infamous reasons are as follows:

1. Because Qin Tussah was too short, no one wrote a fair history for the first emperor. At least, it can be said with certainty that no one will use imperial scholars to whitewash and beautify their ancestors and fabricate history, as emperors did in previous dynasties. For example, Liu Bang, who was born in poverty, actually invented the story of "White Snake Uprising", and attached that Liu Bang was the son of Chi Di and killed White Snake, the son of the ruling white emperor, in order to raise Liu Bang's identity.

2. The new system initiated by Qin Shihuang made the aristocratic adherents of the six countries at a loss. They think that rites and music have collapsed since three generations, so they do not hesitate to oppose it to the end to express their inner fear and helplessness about the disruption of the old order.

3. The changes implemented after Qin Shihuang unified the six countries just harmed the interests of the nobles and the waiting countries to the maximum extent, so they were strongly resisted and opposed by the poor nobles in the six countries. The first emperor was attacked on the way out for the first time, which was initiated by the North Korean aristocrat Sean in Bolangsha. Sean later became an important counselor of Liu Bang and made great contributions to the Western Han Dynasty.
