Wikipedia Overview

Xiandai Hanyu Cidian, also known as A Dictionary of Current Chinese or Contemporary Chinese Dictionary, is an important one-volume dictionary of Standard Mandarin Chinese published by the Commercial Press, now into its 7th (2016) edition. It was originally edited by Lü Shuxiang and Ding Shengshu as a reference work on modern Standard Mandarin Chinese. Compilation started in 1958 and trial editions were issued in 1960 and 1965, with a number of copies printed in 1973 for internal circulation and comments, but due to the Cultural Revolution the final draft was not completed until the end of 1977, and the first formal edition was not published until December 1978. It was the first People's Republic of China dictionary to be arranged according to Hanyu Pinyin, the phonetic standard for Standard Mandarin Chinese, with explanatory notes in simplified Chinese. The subsequent second through seventh editions were respectively published in 1983, 1996, 2002, 2005, 2012 and 2016.
