Money, literature, both belong to China's weights and measures. According to historical records, the Yellow Emperor set five measures: degree, quantity, balance, centimetre and mu. Shun summoned the four kings to coordinate the seasons, rhythms and weights and measures of the tribes; Yu Xia used a ruler as a measuring tool, and his own length and weight as the standard of length and weight.
These legends, to some extent, reflect the germination of ancient weights and measures. The real token can be proved by the inscriptions in the Western Zhou Dynasty, which read "Ten Stems of Gold", "Three Stems of Silk" and "Ten Stems of Gold". Gold is copper, and "Jun" and "Jun" are the unit names of measurement. It shows that before or at the same time as the appearance of metal currency, there have been means to measure weight.
1930s, in order to be in line with international standards, unify China's weights and measures system, solve the obstacles brought by the differences of weights and measures in different regions to economic development, and promote economic development, the Nanjing government carried out weights and measures reform. In order to meet the habitual needs of the broad masses of the people, the "Kuping construction system" was reformed into a "market system".
In order to be in line with international standards, it is convenient to convert the "municipal system" into an international standard system. Specially change "a building scale" to "a city scale", which is equal to 33.33 cm = 0.3 m; One kilometer is equal to two cities. Changing "one kilogram" to "one kilogram" equals 500 grams =0.5 kilograms.
