In the early 8th century, Vajrayana master Huiguo served as abbot and taught in the temple including many foreign monks, such as Japanese monks Kūkai, Ennin and Enchin, Korean monks Huiri and Wuzhen  and Indonesian monk Bianhong. Especially the Japanese monk Kūkai, who brought back his Buddhist teachings to Japan in the year 806 and his influence was part of what made Buddhism popular in Japan.
