It was reported that among Banner people, both Manchu and Chinese (Hanjun) in Aihun, Heilongjiang in the 1920s, would seldom marry with Han civilians, but they (Manchu and Chinese Bannermen) would mostly intermarry with each other.[81] Owen Lattimore reported that during his January 1930 visit to Manchuria, he studied a community in Jilin (Kirin), where both Manchu and Chinese bannermen were settled at a town called Wulakai, and eventually the Chinese Bannermen there could not be differentiated from Manchus since they were effectively Manchufied (assimilated). The Han civilian population was in the process of absorbing and mixing with them when Lattimore wrote his article.[82]
