Latinxua Sinwenz

Latinxua Sin Wenz (Chinese: 拉丁化新文字; pinyin: Lādīnghuà Xīn Wénzì; 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 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.
