Fanqie (反切) is a traditional method of indicating the pronunciation of a Chinese character by using two other Chinese characters, one having the same consonant as the given character and the other having the same vowel (with or without final nasal) and tone. There are seven problematic aspects regarding Fanqie (反切) phonetic notation of polyphonic characters in The Grand Chinese Dictionary, 漢語大詞典. The first, the cited Chinese characters used as phonetic notations are wrong; the second, the attributions of phonological status about some polyphonic characters are not correct; the third, one or two phonetic notations are missing among several pronunciations of the polyphones; the fourth, the materials for phonetic evidences are neglected; the fifth, the evidences of some ancient sounds are lagging because of not finding the earliest evidence in citing ancient sound; the sixth, the main sounds and the secondary ones are reversed; and the last, the selected Chinese characters are not appropriate in some Fanqie phonetics.
