Gwoyeu Romatzyh


 

Gwoyeu Romatzyh ({{zh-stp|s=国语罗马字|t=國語羅馬字|p=Guóyǔ Luómǎzì}}), abbreviated GR, is a romanization (formerly used officially in the Republic of China) with complex spelling rules which allow for tonal distinctions (unlike most other Romanizations, which require additional diacritics or numerals).
