The Qin dynasty (221–206 BCE) standardized the Chinese writing system as part of a broader effort to establish a unified empire under a centralized administration. This initiative, traditionally attributed to the minister Li Si, was essential for several key reasons:12

  • Administrative Efficiency: By creating a standardized script—known as xiaozhuan (small seal)—the government ensured that laws, customs, and weights and measures could be documented and understood consistently across the newly unified territories.12
  • Dissemination of Learning: The modification of characters into a uniform style facilitated a broader and easier dissemination of information, meeting the growing demand for documented records throughout the empire.1
  • Resolution of Ambiguity: Prior to this standardization, the writing system had become increasingly irregular and complex. The reform helped address character ambiguity by refining the system to better represent the language, ensuring that written communication was more intelligible and reliable for governance.13

This standardization laid the foundation for a unified Chinese state and influenced the development of the written language for centuries to come.24
