《詩經》身為五經之首，自古以來就是中國極重要的經典，不僅具有文學的價值，亦是研究周代歷史、社會、文化、名物制度以及語言文字的極重要資料。然而，《詩經》由於著成時代甚早（西周至春秋中期），後來又有儒家《詩序》之自成一說，以及今文三家詩和古文毛詩之爭議，加上歷代學者對於《詩》義之爭論，《詩經》文字義理之複雜繁瑣，堪稱五經之最。 然而，《詩》之難讀，多半是時代差距所造成的，若要探究其義，選取時代相近的經籍文獻以及古文字資料相互驗證，所謂「以經驗經」、「以古文字證經」可說是較為明確的研究方式，加上近幾年來學界對《詩經》的考釋日新月異，亦增加吾人研究之佐助。個人有鑑於此，乃選取《詩經》中的幾處疑難字詞，如〈大明〉「涼彼武王」、〈桑柔〉「民之未戾」、〈雄雉〉「不忮不求（咎）」等，作深入之探討，以求釐清經文的真正意旨，而能還原古經本來的面目。

"The Book of Odes", one book of the Five Classics, has been an extremely important classic in China since the ancient time. It not only has the value of literature, but also is important information for studying history, society, culture, systems, languages and characters of Chou Dynasty. "The Book of Odes" was written earlier during the period of Western Chou Dynasty and the middle Spring and Autumn Period. Later, the "Preface to The Book of Odes" of the Confucian school had their own unique style of interpretation. The controversies over "The Three Schools of the Songs" (an up-to-date classic writing) and "Mao Poetry" (an ancient writing) plus the arguments of scholars about the meanings of "poetry" in the past have made "The Book of Odes" being regarded as a classic with the most complicated meanings and philosophical connotations in the Five Classics. However, the difficulty in understanding "The Book of Odes" is mostly because of the different backgrounds of times. to probe into the meanings of those ancient songs in "The Book of Odes", one may compare the books and literature written during the similar period with the information in the ancient writings for mutual authentication, which is the so-called "interpretation of classics with classics" or "interpretation of classics with ancient writings". Moreover, the examination and interpretation of "The Book of Odes" changed with each passing day in recent years. This would be somewhat of help to our studies. In view of this, the author selected several difficult words from "The Book of Odes", such as "Liang Pi Wu Wang" in "Ta Ming (大明)", "Ming Chih Wei Li" in "Sang Jou (桑柔)", "No damage (忮) No disaster (咎)" in "Male Pheasant (雄雉)", for in-depth study in order to clarify the true meanings of those odes and restore the true colors of the classic.
