Muslims represented the largest religious minority within Song China, although there were many others. There was a community of Kaifeng Jews who followed the exodus of the Song court to Hangzhou once the Jurchens invaded the north in 1126. Manichaeism from Persia was introduced during the Tang; during the Song, the Manichaean sects were most prominent in Fujian and Zhejiang. Nestorian Christianity in China had for the most part died out after the Tang dynasty; however, it was revived during the Mongol invasions in the 13th century. Followers of Zoroastrianism still had temples in China as well. Prospects of studying Chinese Chan Buddhism attracted foreign Buddhists to China, such as Enni Ben'en (圓爾辯圓; 1201–1280) of Japan who studied under the eminent Chinese monk Wuzhun Shifan (1178–1249) before establishing Tōfuku-ji in Kyoto. Tansen Sen states that Buddhist monks traveling from India to China and vice versa during the Song surpassed that of the Tang dynasty, while "Indian texts translated under the Song dynasty outnumbered those completed under the preceding dynasties."
