The transfer of families from Han Banners or Bondservant status (Booi Aha) to Manchu Banners, switching their ethnicity from Han to Manchu was called "Taiqi" (抬旗) in Chinese. They would be transferred to the "upper three" Manchu Banners. It was a policy of the Qing to transfer to immediate families (the brothers, father) of the mother of an Emperor into the upper three Manchu Banners and having "giya" 佳 appended to the end of their surname to Manchufy it. It typically occurred in cases of intermarriage with the Qing Aisin Gioro Imperial family, and the close relatives (fathers and brothers) of the concubine or Empress would get promoted from the Han Banner to the Manchu Banner and become Manchu. The Han Bannerwoman Empress Xiaoyichun and her entire family were transferred to the Manchu Banners due to her status as the mother of an Emperor and their surname was change from Wei 魏 to Weigiya 魏佳.
