Latinxua Sinwenz

Latinxua Sin Wenz (Chinese: 拉丁化新文字; pinyin: Lādīnghuà Xīn Wénzì; literally: "Romanized New Script"; also known as Sin Wenz, Latinxua Sinwenz, Zhongguo Latinxua Sin Wenz, Beifangxua Latinxua Sin Wenz or Latinxua) is a little-used romanization system for Mandarin Chinese. It was usually written without tones under the assumption that the proper tones could be understood from context.

Latinxua is historically notable as being the first romanization system used in place of Chinese characters by native Chinese speakers. It was originally developed by groups of Chinese and Russian scholars in the Soviet Union and used by Chinese immigrants there until the majority of them left the country. Later, it was revived for some time in Northern China where it was used in over 300 publications before its usage was ended by the People's Republic of China.

The work towards constructing the Beifangxua Latinxua Sin Wenz (北方話拉丁化新文字) system began in Moscow as early as 1928 when the Soviet Scientific Research Institute on China sought to create a means through which the large Chinese population living in the far eastern region of the U.S.S.R. could be made literate, facilitating their further education.

This was significantly different from all other romanization schemes in that, from the very outset, it was intended that the Latinxua Sin Wenz system, once established, would supersede the Chinese characters. They decided to use the Latin alphabet because they thought that it would serve their purpose better than Cyrillic. Unlike Gwoyeu Romatzyh, with its complex method of indicating tones, Latinxua Sin Wenz system does not indicate tones at all.

The eminent Moscow-based Chinese scholar Qu Qiubai (1899–1935) and the Russian linguist V.S. Kolokolov (1896–1979) devised a prototype romanization system in 1929.
