This is actually a biased evaluation which results from a misinterpretation of the theory. The present study considers that the neighbor-syllable (傍紐) defect in the theory actually refers to avoiding characters of the same consonant and vowel within ten continuous characters, and the minor-rhyme (小韻) defect means to prevent homophonous characters between two continuous sentences. The four types of defects should be avoided because multiple characters of similar phonetic sounds arranged closely in a literary work would make it difficult to pronounce and identify the words. Examining the phonological phenomena in available literature, the neighbor-syllable defect has already been raised as early as around the end of the Han dynasty, far prior to Shen Yue and his followers.983359 bytesapplication/pdf八病、韻紐四病、歷史音韻、詩病(the eight defects, the four rhyme and syllable defects, historical phonology, poetic defects）journal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/282312/1/0053_201606_1.pdf
