In the 1920s, the Vietnamese alphabet became the country’s dominant writing system. By the 1930s, the use of Sino-Vietnamese characters was largely restricted to books with limited woodbock printings intended for the Buddhist clergy. In more recent times, the traditional characters have been used mainly in calligraphy, such as wedding decorations. In 2012, manuscripts in Classical Chinese were translated to support Vietnam's claim to the Paracel Islands.
