The revised “Chinese Comprehensive Dictionary” (Second Edition) still contains citation errors, primarily in the form of omissions, additions, transpositions, and misquotations in the cited texts, as well as errors in the sources of citations (including both the main text and the “List of Cited Works”). These errors range from individual category oversights to comprehensive mistakes, creating “serious flaws” in the citations that significantly affect the compilation quality of the “Chinese Comprehensive Dictionary”. In the past, citation errors have been generically attributed to the “negligence” of the compilers, a view that lacks specificity. This paper points out 21 examples of citation errors in the “Small” and “Mouth” radicals of the “Grand Dictionary” and uses them as a basis for a targeted exploration of the causes of citation errors in the “Grand Dictionary”. Corresponding revision suggestions are proposed.
