Qin Shihuang: In 22 1 year BC, the unification of China was inevitable. From 230 BC to 22 BC1year, Qin Shihuang defeated Korea, Zhao, Wei, Chu, Yan and Qi in1year, ending the 500-year feudal regime in China since the Spring and Autumn Period and establishing the first unified dynasty in China history.

Qin Shihuang's policy after reunification

Books are the same, cars are the same track, unified measurement:

If Qin Shihuang realized the unification of national political system with the system of "three publics and nine nobles" and the system of counties and counties, then he also realized the unification of economic system and ideological culture with the same book, the same train and unified measurement.

During the Spring and Autumn Period and the Warring States Period, the vassal states went their own way and used different languages. If this phenomenon is left unchecked in the Qin Dynasty, it will bring great inconvenience to the implementation of government decrees, economic and trade exchanges and cultural exchanges. To this end, Qin Shihuang ordered Prime Minister Li Si to sort out these words.

On the basis of Qin script and combining the advantages of six scripts, Lishu created a unified font as the official standard script. At the same time, on the basis of Qin Zhuan, we simplified it and developed another font of official script for daily writing.

Cars are on the same track-during the Spring and Autumn Period and the Warring States Period, the width of roads between vassal states is different, and the size of wagons is also different. After the reunification of the country, this phenomenon has seriously affected the traffic between places and restricted the economic development.

Qin Shihuang ordered the construction of three equator centered on Xianyang, one to the east, one to the south and one to the north, which is equivalent to the current national highway. The track in the driveway is 6 feet wide. At the same time, the distance between the two wheels on the carriage will be changed to 6 feet, which is the same as the track on the chidao. In this way, it is beneficial to the long-distance transportation of carriages.
