Erya is the first annotation book in China and the first Chinese dictionary. It collects more than 4,000 characters, words, dialects, and proper nouns and is thus a major source referenced in Pianzi leibian, which contains more than 1,000 pieces of information from Erya. Quoting Erya provides clear information of word origins and offers direct meanings. The contents cited in Pianzi leibian are not identical to those in the existing Erya, and some has even been lost. Pianzi leibian has retained a considerable amount of text of Erya and thus is of high research value. However, Pianzi leibian did not do a comprehensive job in citing Erya, and the gaps must be noted when using Pianzi leibian as a reference book. This study aimed to enhance the reader' understanding of Pianzi leibian.
