On the basis of unified calculation, what are the benefits of Qin's destruction of the six countries to the surrounding economic and cultural exchanges?

Measures to consolidate reunification: During the Warring States period, there were great differences in currency, weight and writing among countries, which affected the economic and cultural exchanges between different places. After the Qin dynasty destroyed the six countries, Qin Shihuang stipulated the unified use of round square hole copper coins throughout the country. At the same time, unified measurement has made unified regulations on size, bucket size and weight. The Qin dynasty also unified the characters, taking Xiao Zhuan as the national standard, and abolished the original six-country characters. Later, strokes were popularized.

In order to strengthen ideological control, Qin Shihuang accepted Lisi's suggestion and issued a book burning order, stipulating that except for the official government, only the people were allowed to leave books on medical skills, divination and self-cultivation, and all other books were burned: anyone who talked about Confucian poetry books in the future would be sentenced to death. He also buried a group of Confucian scholars who secretly criticized him in Xianyang. This is the "burning books to bury Confucianism" in history.

Qin Shihuang attached great importance to talents, adapting to the weather and people.
