食貨　初虞夏商之世。幣金有三品。或黃或曰或赤或錢或布或刀或龜具。至是太公望乃立九府圜法。錢圜凾方。輕重以銖。布帛廣二尺二寸為幅。長四丈為匹。故貨寶於金。利於刀。流於泉。布於布。束於帛（漢食貨志）。

Treatise on Food and Money: Formerly, in the eras of Yu, Xia, and Shang, currency and metals had three grades: yellow, white, or red, whether coins, spade money, knife money, or tortoise shells. At this time, Grand Duke Wang established the round currency system of the Nine Treasuries: coins were round with a square hole, their weight measured in zhu; cloth and silk were two feet two inches wide for a bolt, and forty feet long for a piece. Thus wealth was valued in gold, made advantageous through knives, circulated through coins, distributed through cloth, and wrapped in silk (Hanshu, 'Treatise on Food and Money').
