Hokkien, especially Taiwanese, is sometimes written in the Latin script using one of several alphabets. Of these the most popular is Pe̍h-ōe-jī (traditional Chinese: 白話字; simplified Chinese: 白话字; pinyin: Báihuàzì). POJ was developed first by Presbyterian missionaries in China and later by the indigenous Presbyterian Church in Taiwan; use of this alphabet has been actively promoted since the late 19th century. The use of a mixed script of Han characters and Latin letters is also seen, though remains uncommon. Other Latin-based alphabets also exist.
