In 520 CE the Chinese monk Song Yun visited Gandhara and ancient Peshawar during the White Hun era, and noted that it was in conflict with nearby "Kapisa". The Chinese monk and traveler Xuanzang visited ancient Peshawar around 630 CE, after "Kapisa" victory, and expressed lament that the city and its great Buddhist monuments had decayed to ruin—although some monks studying Hinayana Buddhism continued to study at the monastery's ruins. Xuanzang estimated that only about 1,000 families continued in a small quarter among the ruins of the former grand capital.
