Qin Shihuang himself was the supreme decision-maker of "the same text in writing, the same track in carriages, and the unification of weights and measures." The specific implementation and correction work was the responsibility of specialized agencies and officials.
The executor of unified weights and measures
According to the edict issued by Qin Shihuang in the 26th year of his reign, "There are different laws and regulations, but they are all clearly defined." Prime Minister Wei Zhuang and Wang Wan are the main responsible persons at the central level. Governments in various regions have full-time officials and craftsmen who conduct "certification and calibration" of local weights and measures instruments according to central standards every year.
The agency that promotes unified writing
From the unearthed Qin bamboo slips and clay seals, it can be seen that the Qin Dynasty had official positions such as "Book Tongwen Cheng" and "Weights and Measures School", which were responsible for the standardization and promotion of writing, laws and regulations, and weights and measures. They could be regarded as the "correctors" of the country at that time.
Physical "correctors": imperial edicts and inscriptions
Cultural relics such as the copper imperial edict engraved with the imperial edict are themselves the physical standards for "correction". They not only correct the textual error in the "Historical Records" that the prime minister's "Kai Lin" was actually "Kui Sha", but also provide archaeological evidence for the Qin Dynasty's efficient implementation of standardization.
