Liu An (179-122B.C.) and Ssu-Ma Ch'ien (145-86B.C.) first praised Chu Yuan's personality in their literary criticism. Since then, the commentary of the Songs of Chu by the Songs of Chu by the scholars of the Han dynasty had been focusing on the point of the correspendence between the author's personality and the style of his works. At the end of the Western Han dynasty, Yang Hsiung (53B.C.-5A.D.) started to raise doubts about Chu Yuan's personality; however, he still followed the traditional pattern and commented on the Songs of Chu in term of the author's personality. During the Eastern Han dynasty, Han dynasty, Pan Ku (32-92A.D.) most vehemently criticized Chu Yuan by pointing out that Chu Yuan revealing excellent ability in his poems tended to display his own talent by complaining about the king and thus ignored to protect himself in a chaotic political situation. Although Pan Ku approached the works of Chu Yuan from different perspective, he still didn't get a correct understanding of the work, because the evaluated it with the criterion of the thoughts of Confucianism. Therefore, Pan Ku failed to appreciate the rich imagination that Chu Yuan provided in his poems. Later on, Wang Yih (?-163A.D.) based on all the different comments synthesized, he asserted that what Chu Yuan wrote while in exile was poems of gentle remonstrance not of complaining. Wang Yih was being able to make such a true, unique yet sympathetic interpretation was based on the fact that he had a deeper understanding Chu Yuan and his works. As he and Chu Yuan came from the same town, he knew that Chu Yuan and the king were of the same clan, and with loyalty in mind, Chu Yuan would not betray either his own home land or the king. Rather, in his poems he employed figurative speech with many metaphors and similes to imply his irony. Based on better knowledge of the author and his poems, Wang Yih proposed a well-constructed literary critical system. Thus, he was noted for synthesizing all the discussions of Chu Yuan's personality and poems, and providing decisive comments for scholars in Han dynasty and those after him.
