When Wang Mang usurped the throne from the Han dynasty and established the Xin dynasty, he followed the standards of the past and had the measures recast, which were known by the name Chia liang (measures). This Chia measure is a combination of five such measures. The main body is a hu. Turned over, it becomes a tou. The left measure is a sheng, and the right one is a ho, below which is a he. Two he equal one ho, ten ho equal one sheng, ten sheng equal one tou, and ten tou equal one hu. The inscription explains the origins, individual parts, and dimensions of the individual parts.
