Warring States, Western Han, and Song dynasties for height and width measurements

Using online collection data from Chinese museums and archaeological reports, the study selected ten trousseaus from each of the Warring States, Western Han, and Song dynasties for height and width measurements。The selection was not based on any specific criteria regarding rank, region, or craftsmanship; rather, it was intended to reflect the dimensional ranges of trousseaus in each period.The purpose is to better demonstrate that trousseau height increased significantly over time, while diameter decreased in the later period.
