When the new currency was adopted in Taiwan, unused stamps were immediately converted into new values to meet urgent requirements. At the same time arrangements were made for the printing of new stamps. The design of the first stamp issue in the new currency is the portrait of a patriotic hero General Cheng Cheng-kung copied from a drawing kept in the Taiwan Provincial Museum.The stamps bear his name〝延平郡王鄭成功〞(Yenping Prince Cheng Cheng-kung) inscribed under his portrait. 　　Those of 20￠and 50￠denominations were issued on June 26, 1950, while the other denominations were issued on September 26 of the same year.
