It is believed that the marriage of the Hormuzian Persian girl to Lin Nu which accompanied his conversion to Islam is what caused the other branch of the family to change their surname which is why the same family uses two surnames, Lin and Li, since they were extremely xenophobic to foreign religions and marriage to other ethnicities in the atmosphere after the Yuan dynasty collapsed.[23][24] The biography of Lin Nu says he married a Semu girl and converted to Islam at a mosque in Hormuz in 1384 before coming back to China.[25] Li Guangqi said his uncle Lin Nu's marriage to the foreign girl and conversion to her religion caused his branch of the family to exclude his uncle's descendants from the genealogy because they practiced Islam and change the surname of his own branch of the family to Li to disassociate them from the Lin surname.[26] Li Guangqi attacked the religion and customs of the Semu including Islam and other foreign religions saying they were incompatible with Chinese culture and that their language sounded like owl screeching and their script resembled worms.
