Although most of the simplified Chinese characters in use today are the result of the works moderated by the government of the People's Republic of China in the 1950s and 60s, character simplification predates the republic's formation in 1949. One of the earliest proponents of character simplification was Lufei Kui, who proposed in 1909 that simplified characters should be used in education. In the years following the May Fourth Movement in 1919, many anti-imperialist Chinese intellectuals sought ways to modernise China. In the 1930s and 1940s, discussions on character simplification took place within the Kuomintang government, and many Chinese intellectuals and writers have long maintained that character simplification would help boost literacy in China. In many world languages, literacy has been promoted as a justification for spelling reforms. The People's Republic of China issued its first round of official character simplifications in two documents, the first in 1956 and the second in 1964. In the 1950s and 1960s, while confusion about simplified characters was still rampant, transitional characters that mixed simplified parts with yet-to-be simplified parts of characters together appeared briefly, then disappeared.
