한족
Duanfang was actually Han Chinese even though he was under a Manchu banner. Some Han Chinese joined Manchu banners directly, instead of joining the separate Han Chinese banners. Han Chinese in the Manchu banners became Manchucized. The Manchu White Banner were joined by some Zhejiang Han Chinese with the family name Tao who defected to the Manchus towards the end of the Ming dynasty. Their last name was changed to the Manchu sounding "Tohoro". Duanfang was one of their descendants.
