However, up to now there are still very few comparative studies on its translations, and among the very few comparative studies on Gitanjali, Bing Xin's version is regarded by most scholars as more popular and readable. In order to analyze the differences between the two Chinese versions by Bing Xin and Bai Kaiyuan in an objective and scientific manner, thispaper makes a corpus-based comparative study on the two versions. The results show that, compared to Bing Xin's version, Bai Kaiyuan's version boasts greater words diversity, stronger readability and deeper emotions. The differences between these two versions can be explained by the development of Chinese vocabularies and rich modifiers which are used by Bai Kaiyuan.展开更多
