An excellent set of reviews of recent translations of chinese poetry by Madeleine Thien HERE in the New York Review of Book.
It includes the following explanation.
The essential experience of Chinese poetry is all but untranslatable. Eliot Weinberger, Lucas Klein, Burton Watson, Stephen Owen, and David Hinton, among others, have set down superb translations, while noting that, in bringing Chinese poetry into English, more things go missing than in translations from other languages. Word-for-word translations, writes François Cheng in his masterful Chinese Poetic Writing (1977), can give “only the barest caricature.” Ha Jin describes a particular Li Bai poem as obtaining a beauty that “can be fully appreciated only in the Chinese.” Hinton observes that a particular line, severed from its radically different philosophical context, “fails absolutely in translation.” But the incommensurability of Chinese (logographic) and English (alphabetic) written systems begins the moment a mark is made. Chinese ideograms are composed of strokes, and each of the brushstrokes references others. Cheng gives this line from Wang Wei as an example, followed by its literal translation:
木 末 芙 蓉 花
branch end magnolia flowers
The character for “branch” 木 begins to transform at its tips 末 and bud into life. In the third character, 艹 (the radical for “grass” 艸 or “flower”) bursts forth from the crown of the words 芙蓉 (magnolia) and ends in 花 (flower). Further, in a simultaneous layer of images, the third character, Cheng writes, “contains the element 天 ‘man,’ which itself contains the element 人 ‘Man’ (homo),” or person. “Face” 容 is visible in the fourth ideogram, and the fifth contains 化 (transformation). Thus the line also records a human trajectory: spiritual metamorphosis and then mortality embedded in nature itself.
