[[Ancient Chinese coinage|In China]], early round coins appeared in the 4th century BC and were adopted for all China by Emperor [[Qin Shi Huang Di]] at the end of 3rd century BC.<ref>{{cite book |last1=Schaps |first1=David |title=The Invention of Coinage and the Monetization of Ancient Greece |date=2004 |publisher=University of Michigan Press |isbn=978-0472113330 |page=235 |url=https://books.google.com/books?id=pqINoVlD0RcC&pg=PA235 |language=en}}</ref> The round coin, the precursor of the familiar [[Cash (Chinese coin)|cash coin]], circulated in both the spade and knife money areas in the Zhou period, from around 350 BC. Apart from two small and presumably late coins from the State of Qin, coins from the spade money area have a round hole and refer to the ''jin'' and ''liang'' units. Those from the knife money area have a square hole and are denominated in ''hua'' (化).

Although for discussion purposes the Zhou coins are divided up into categories of knives, spades, and round coins, it is apparent from archaeological finds that most of the various kinds circulated together. A hoard found in 1981, near Hebi in north Henan province, consisted of: 3,537 Gong spades, 3 Anyi arched foot spades, 8 Liang ''Dang Lie'' spades, 18 Liang square foot spades and 1,180 Yuan round coins, all contained in three clay jars.
