The Yi script (Yi: ꆈꌠꁱꂷ nuosu bburma [nɔ̄sū bū̠mā]; Chinese: 彝文; pinyin: Yí wén) is an umbrella term for two scripts used to write the Yi language; Classical Yi (an ideogram script), and the later Yi Syllabary. The script is also historically known in Chinese as Cuan Wen (Chinese: 爨文; pinyin: Cuàn wén) or Wei Shu (simplified Chinese: 韪书; traditional Chinese: 韙書; pinyin: Wéi shū) and various other names (夷字、倮語、倮倮文、畢摩文), among them "tadpole writing" (蝌蚪文) (Wikipedia)
