Answer:
The standarization of non-alphabetic written script across all of China
Step-by-step explanation:
This replaced the previous regional scripts. This script was simplified to allow faster writing, useful for record keeping. The new script enabled parts of the empire that did not speak the same language to communicate together, and led to the founding of an imperial academy to oversee all texts. As part of the university effort, older philosophical texts were confiscated and restricted (though not destroyed, as accounts during the Han Dynasty would later claim).
