The English language edition of One Lesson One Exercise series is based on the latest Chinese edition of the Yi Ke Yi Lian series， a multiple award-winning bestseller， published by East China Normal University Press. Since it first appeared in the early 1990s， the Chinese edition of the Yi Ke Yi Lian series has been regularly revised and used by millions of students in primary and secondary schools all over Shanghai and beyond. The awards it has won include， for example， an official listing by an authoritative organization of China's book industry in 2009 as one of the China's "300 Most Influential Books in the 30 Years since Reform and Opening Up" （1978 - 2008）， and in 2015， the series was awarded the title of "Shanghai Famous Trademark" by the Shanghai Administration for Industry and Commerce for the third time， the only book （series） awarded the honour by the Administration.
To keep the originality and authenticity of the Chinese edition， the English language edition is essentially a direct translation of the Chinese edition， so the loss of meaning in translation is kept to a minimum. When it is not possible to have a direct translation， necessary adjustments or changes have been made. For example， in Chinese， a Deng Shi is different from a Fang Cheng; however in English， the word "equation" can apply to both a Deng Shi and a Fang Cheng. In this case， the questions in the Chinese edition were slightly changed when possible or deleted otherwise in the English language edition. When appropriate， a footnote has been added to remind the readers of the difference from the original Chinese edition. For readers' convenience， a Chinese-English mathematics glossary is also added in each book of the English language edition.
