With careful study of the Chinese Nomenclature of Organic Compounds (2017), the major changes in the new regulations compared with the 1980 edition are summarized, including the order of main characteristic groups, the listing order of substituent groups, the numbering order of main structure, the location of substituent group and main group numbering, and the "order rule" in stereochemistry. In order to provide a reference for the study and teaching of Organic Chemistry in a concise and clear way, this paper summarizes the aspects.

Key words: Organic compounds nomenclature, Characteristic group, Substituent group, The lowest order rule, Cahn-Ingold-Prelog sequence rule
