Manchu[aka Man, Mandschurisch, Mandschu]
The official number [of the ethnic population] has fluctuated greatly depending on the ethnopolitical circumstances in the country.
Degree of speakers' competence: mainly rudimentary, with some non-fluent individuals still preserving a passive knowledge of the language; the knowledge of Written Manchu is somewhat more common among educated individuals, but Chinese is the sole everyday language used for both oral and literary purposes.
Originally scattered all over historical Manchuria, China, with small remnant groups of speakers today preserved in the Aihui region (in the middle Amur basin) and Fuyu county (in the Nonni basin) of the province of Heilongjiang, as well as, possibly, in some localities within the province of Liaoning; linguistically assimilated groups and individuals identifying themselves with the Manchu nationality are registered in all parts of China.
Among the urbanized Manchus, the language is no longer spoken but it is still studied in an ongoing literary tradition.
