Besides Czech, other languages that are spoken here are Polish, Ukranian, German and Slovakian, influenced by the nations that border the Czech Republic. There is also a significant Roma population in Czechia, as well as other parts of Europe, who speak Romani, which is heavily influenced by the Indian Hindi language. Since many Vietnamese immigrants have been moving to Czechia since the communist era and make up one of the largest foreign ethnic groups in the country, Vietnamese is commonly spoken in some areas as well.
Czech banknotes included the 100, 200, 500, 1000, 2000 and 5000 korunas (Kč, or Czech crowns) and have many important figures on the bills. For example, on the 100 Kč , there is a picture of the Holy Roman Emperor Charles IV, the father of the Czech Republic and King of Bohemia in the 1300s. Many places in Prague are named after him, such as the Charles Bridge, Charles University and Charles Square. On the 500 Kč and 2000 Kč are two famous women who impacted Czechia, the famous writer, Božena Němcová and Emmy Destinn, an opera singer from Prague.
