Mu Ying was a Chinese general during the Ming Dynasty, and an adopted son of its founder, the Hongwu Emperor. Mu Ying was one of the few capable generals who survived the massacre of Hongwu. According to Chinese Muslim traditions; Ma Hou, the first wife of Hongwu, was a Muslim; he also had Mu Ying an adoptive Muslim son. When the Ming dynasty emerged Emperor Zhu Yuanzhang's military officers who served under him were given noble titles which privileged the holder with a stipend but in all other aspects was merely symbolic. Mu Ying's family was among them. Special rules against abuse of power were implemented on the nobles. Yunnan remained in his family. Mu and his descendants guarded Yunnan, a province near Burma and Vietnam, until the end of the Ming dynasty. As late as the 1650s, his descendant Mu Tianbao was one of the main supporters of the Yongli Emperor, the last emperor of the Southern Ming, and accompanied the fugitive emperor all the way into Burma.
Bai explained that he failed to find any reliable proof of Mu Ying was a Hui Chinese. Thus, "it sounded unconvincing" to "identify him as one of Hui people". However, later, the biography of Mu was included in A History of the Chines Hui People, which was edited by Bai without further evidences. Michael Dillon wrote "There is no suggestion in most western accounts of Mu Ying's career or the Chinese sources on which they draw that Mu Ying was anything other than a Han Chinese by origin, yet he has been included in the major series of studies of the lives of eminent Hui as a Muslim without any comment. The surname Mu is also common among Chinese Muslims and is probably derived from Muhammad, although it is normally written with a different Chinese character. The character used to write Mu Ying's surname is the one associated with washing the hair and which appears on signs in every mosque in China as the first character of muyu the ritual baths to be used before prayer." He concludes that "He was probably descended from an old Muslim family but there is no evidence that he was a practising Muslim." Jonathan Neaman Lipman notes that Mu Ying is among a number of generals "unambiguously claimed as Muslim by Sino-Muslim scholars" mentioning specifically Bai Shouyi. He writes that "There is considerable doubt among non-Muslim scholars as to the “Muslim” identity of most of these generals, but Sino-Muslims assert their “Huiness” unequivocally. Tazaka, Chugoku ni okeru kaikyo, 861, for example, questions not only Chang Yuqun’s identification as a Huihui but that of many others as well. F. Mote, in Goodrich and Fang, Dictionary, 1079–83, indicates that we have no evidence that Mu Ying was born a Muslim, and the story of his adoption and upbringing in Zhu Yuanzhang’s intimate circle certainly indicates that he was not raised as one."
