===Economic reforms===
Qin Shi Huang and [[Li Si]] unified China economically by standardizing the [[Chinese units of measurement|weights and measurement]]s. Wagon axles were prescribed a standard length to facilitate road transport.<ref name="Veeck" /> The emperor also developed an extensive network of roads and canals for trade and communication.<ref name="Veeck" /> The currencies of the different states were standardized to the [[Ban Liang]] coin.<ref name="Chang" /> The forms of [[Chinese characters]] were unified. Under Li Si, the [[seal script]] of the state of Qin became the official standard, and the Qin script itself was simplified through removal of variant forms. This did away with all the regional scripts to form a universal written language for all of China, despite the diversity of spoken dialects.<ref name="Chang" />
