Korean currency
In 1902, won was introduced as the official currency unit replacing yang at 1 won = 5 yang. The bank of Korea was established 1909 but soon after in 1910, Imperial Japan annexed Korean Empire. Under Colonial rule, the country was made to use the currency unit "yen" in the name of Korean yen, which took over the Korean won at par. After the division of Korea, the state of South Korea was established and recognized in 1948, and won was again made the official currency of the new state. "jeon" was made the subunit of the currency that divided it into 100 equal parts. Bank of Joseon issued the currency for independent South Korea for the first time that too in banknotes only.
Yuan (currency)
The symbol for the yuan (元) is also used in Chinese to refer to the currency units of Japan "(yen)" and Korea "(won)", and is used to translate the currency unit "dollar" as well as some other currencies; for example, the United States dollar is called "Meiyuan" () in Chinese, and the euro is called "Ouyuan" (). When used in English in the context of the modern foreign exchange market, the Chinese yuan (CNY) refers to the renminbi (RMB), which is the official currency used in mainland China.
