The article focuses on the philological study of Xuanzang’s translations in his later years. It examines the change of the translation conditions, including the decrease in the number of assistants and stylists of the translation team. Through the sample analysis of the comparison between the Sanskrit text and the Chinese translation of Praj āpāramitā sutras, it can be seen that in spite of the change of conditions, Xuanzang’s translation is still faithful to the Sanskrit texts. Further, to better follow the Chinese translation tradition and spread the newly translated scriptures, Xuanzang adopted the rendering of other scriptures to adjust his translation. The reason behind his persistence on the translation style has been revealed as his desire of improving Chinese Buddhist thoughts and atmosphere through the sophisticated logical thinking of Indian Buddhism, especially the Yogācāran thoughts. Besides, all of his political activities, including his socializing with royal families, served to his translation and propaganda purposes.
