Early in the 14th century, a Persian Al-Qudsan Al-Dhaghan Nam (伊本·庫斯·德廣貢·納姆) was sent to Quanzhou by Külüg Khan for assisting grain transportation by sea.

It was politically expedient to claim they were descendants of Guo Ziyi in order to be better accommodated by local people and later the Ming dynasty government.

[6][7] The Chinese government's Historic Artifacts Bureau preserved tombs of Arabs and Persians whom Hui are descended from around Quanzhou.

[8] Many of these Hui worship their village guardian deities and are non-Muslims; they include Buddhists, Taoists, followers of Chinese Folk Religions, secularists, and Christians.

[15] They were then distressed and disturbed at the fact that their claim of descent from Guo Ziyi contradicted their being Hui, which required foreign ancestry.
