Until 1987, Gansu was rendered in the postal romanization and Wade-Giles as Kansu, which was gradually replaced by pinyin starting in 1958. The spelling of the province is also spelled in Mandarin Phonetic Symbols II (1986) and Tongyong Pinyin (2002) adopted by Taiwan, who would later adopt Hanyu Pinyin in 2009.
