Chang Yuchun and Hu Dahai are Hui people according to folklore.
There are also legends that Li Shanchang and Xu Da are also Hui people. In China, especially the Hui people's settlements, Zhu Yuanzhang and Ma Huanghou, the Ming emperors, and the civil servants and military commanders who helped Zhu Yuanzhang create the world in the Ming Dynasty, are mostly Hui people, such as Li Shanchang, Xu Da, Chang Yuchun, Feng, Hu Dahai, Aquamarine, Tanghe, Deng Yu and Huayun. Before the uprising, they not only knew each other, but also became brothers of the Hui people, so the people had "ten". The official history of the Ming Dynasty did not mention Zhu Yuanzhang's clan and religious beliefs, but only recorded that he was a "monk" before the uprising, without including the clan and religious beliefs of military commanders such as Chang Yuchun, Hu Dahai, Li Wenzhong, Ding Dexing, Huayun and Mu Ying.
Before and after the establishment of the Yuan Dynasty, Mongolians went to the Western Ocean many times, and recruited a large number of Arabs and Central Asians to form a "pro-army in the Western Region" to enter China. Among them, craftsmen, businessmen, militarists, farmers, scholars, dignitaries and scholars were regarded as "Hui people" in the Song Dynasty. These people married and settled with Han and Mongolian women, formed their ancestral home in the western regions, and integrated into the Han descent and cultural customs.
In fact, it is a modern thing that the Hui nationality is listed as a nation alone. Distinguish between religions in Ming and Qing dynasties, discriminate against their religions, and discriminate against their life traditions under the influence of religions. In other words, it is not regarded as a blood alien, but as a heresy different from China's traditional cultural customs.
As far as blood relationship is concerned, ancestral home does not represent a nation. Since ancient times, many nomadic people outside the frontier have merged with the Han nationality. At present, there is a great genetic gap between the Han nationality in the north of Huanghuai and the Han nationality in the south of the Yangtze River. Because the north has been led by other nationalities for a long time, ethnic integration is very common.
Among the Hui people, there are also such cases, many of which were later joined because of forced or voluntary religious beliefs. For example, in the northwest, a descendant of Confucius is the Hui nationality. Others are directly called Hui people, because their ancestral home is in the Middle East, and they are probably not religious. For example, many people may be like this in the late Yuan Dynasty and early Ming Dynasty.
