The
Song Dynasty hired Muslim warriors from
Bukhara to fight against
Khitan nomads. 5,300 Muslims from
Bukhara were encouraged and invited to move to China in 1070 by the Song emperor
Shenzong to help battle the
Liao empire in the northeast and repopulate areas ravaged by fighting. The emperor hired these men as mercenaries in his campaign against the Liao empire. Later on these Muslims were encouraged to settle between the Song capital of
Kaifeng and Liao capital of
Yanjing (modern day
Beijing) in order to create a
buffer zone. China's northern and northeastern provinces were settled by Muslims in 1080 when 10,000 Muslim women and men were invited into China. They were led by the Amir of Bukhara, Sayyid "So-fei-er" in Chinese. He is called the "Father" of
Chinese Islam. Islam was named by the Tang and Song Chinese as the "law of the Arabs" ( ). Su fei-erh gave Islam the new name of "the religion of the
Huihui" ( ). ==Descendants==
