This essay aims to explore and analyze the origins, meanings as well as
the emotional and pedagogical functions of the idiom “Ch’ing-jen yen-li
ch’uHsi-shih” (A beauty emerges from the eye of her lover), with additional comments on the idiom “Tung-shih hsiao-p’ing” (Aping a
beauty). After examining and studying relevant literature, I have uncovered that the idiom “Ch’ing-jen yen-li yu Hsi-shih” (A beauty exists
in the eye of her lover) originated in Chuang-tze in the 11th century, while both “Ch’ing-jen yen-li ch’uHsi-shih” and “Tung-shih hsiao-p’ing” came out in the sixteenth-century. In conclusion, inherent in the idiom
“Ch’ing-jen yen-li ch’u Hsi-shih” is the positive implication of
“beautification” and “discovery,” which, when used in the cultivation of the senses, could help one realize the importance of respecting and caring the significant others. The idiom is also useful both in teaching for inspiring a student to think or recognizing his/her merits and in research for initiating a novel topic or uncovering answers that have never been noticed. What has resulted from using these idioms would, in short, help provide answers and stimulation for teachers, students, and those who see much in cultivating emotional relationship with others.
