Tongyong Pinyin (Chinese:通用拼音; Hanyu Pinyin:Tōngyòng Pīnyīn; Tongyong Pinyin:Tongyòng Pinyin; literally: "Universal/General Usage Sound-combining") was the official Romanization of Mandarin Chinese in the Republic of China (ROC, also called Taiwan) between 2002 and 2008. The system was unofficially used between 2000 and 2002, when a new romanization system for the Republic of China was being evaluated for adoption.
