Emperor Tang Taizong (599-649) invaded Goguryeo in 645 but failed to conquer her because of severe weather and strong resistance led by Yeon Gaesomun (603-666). This paper argues that official histories including Jiu Tangshu (Old Book of Tang) and Xin Tangshu (New Book of Tang) focus on Emperor Tang Taizhong's legitimacy to invade Goguryeo because Yeon Gaesomun's coup d'etat overthrew Yeongnyu-wang. These two histories also pay extra attention to Yeon Gaesomun's negative characters. Novels about Tang-Goguryeo War including Xue Rengui zheng Liao shi lue (薛仁贵徵辽事略), Tang shu zhi zhuan tong su yan yi (唐书志传通俗演义), and Shuo Tang hou zhuan (说唐后传) take a different approach to heal China's wounded pride. Instead of focusing on diplomatic and military legitimacy, these stories blur China's loss by creating a national hero Xue Rengui whose military skills, loyalty to Tang Dynasty, and dauntless rescue of Emperor Tang Taizong were constantly emphasized.展开更多

Based on Nida's "functional equivalence" theory as the theoretical basis of the study, two different English versions of five-character jueju"Jiang Xue were chosen as the research objects, and studied from two perspectives, namely romantic charm including artistic images and conceptions and artistic form including language employed and rhythms to examine whether the two English versions have reproduced the source poem as it was.
