The aim of this study was to review the Chinese translation errors in 31 English/Chinese bilingual children's picture books. While bilingual children's books make definite contributions to language acquisition, few studies have examined the quality of these books, and even fewer have specifically focused on English/Chinese bilingual books. (Available research on bilingual books is with English/Spanish bilingual books and refers only to general issues in those books.) In this study, Chinese translation and Pinyin errors were noted (in English/simplified-Chinese bilingual books, English/simplified-Chinese bilingual books with Pinyin, and English/traditional-Chinese bilingual books). Findings identified eight types of Chinese translation errors and five types of Pinyin errors. The authors conclude that there are numerous errors in translation, that translation skills need improvement, and that publishers need to look more closely at (and have higher standards for) translators.
