Why did Manchu and Mongolian get married?

Man (then neither called Man nor Jurchen) came from Tunguska and lived in Changbai Mountain. He claimed to be the Jurchen of Jianzhou (borrowing the name of Jurchen to get Ming's asylum), and the number was too small. So he recruited Jurchen (Hercynian Jurchen Association, Wula and Hada) to join in, robbed Daming, and Ramon joined in, but the number of Mongols was large (after taking office, the method of using Guo Jia to support most Mongolian men as monks was greatly reduced). ), afraid to rob to rob to cause infighting uneven distribution of spoils, so get married. Later, the soldiers of the Ming Dynasty were incorporated and surrendered, and Huang Taiji ordered that they should no longer be called Nuzhen, but be renamed as the flag bearer (similar to Dangyuan), who could enter the flag with military merit. The flag bearer was later called Manchu, and now 90% of them are Han Chinese (except the descendants of the Eight Banners of the Han Army who made meritorious deeds). In the 1980s, in order to enjoy preferential treatment, the whole village, township and even county changed the immigrants from Shandong and Hebei to Manchu), and many of them were Mongolians (Eight Banners and Yehe Department, and Yehe Department in Cixi was the Tumote tribe in Mongolia).
