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.
Korea at the 2018 Winter Olympics
In January 2018, it was announced that the South Korea women's national ice hockey team would be amalgamated with a group of North Korean players to form a single Korea women's national ice hockey team in the tournament. They competed under the country code "COR", from the abbreviation of French word "Corée". (The country code “KOR” is already used for South Korea; the IOC uses “PRK” for North Korea.) The anthem which played when the Korea team played in international ice hockey is the folk song "Arirang" instead of the national anthems of either South Korea or North Korea. The team's uniform featured the silhouette of the Korean peninsula with the text "Korea". Because of ongoing U.S. sanctions against North Korea, the uniforms were made by a Finnish company instead of official sponsor Nike.
