During Xuanzang's travels, he studied with many famous Buddhist masters, especially at the famous center of Buddhist learning at Nalanda. When he returned, he brought with him some 657 Sanskrit texts. With the emperor's support, he set up a large translation bureau in Chang'an (present-day Xi'an), drawing students and collaborators from all over East Asia. He is credited with the translation of some 1,330 fascicles of scriptures into Chinese. His strongest personal interest in Buddhism was in the field of Yogācāra (瑜伽行派), or "Consciousness-only" (唯識).
