Chinese authorities have set up Tibetan night classes in “improving civility” in Driru County in Nagchu Prefecture. Voice of America reports that attendees are being taught language, but not their local Nagchu dialect, eg, they are told not to use their usual greeting Kho-re. Last year the authorities there started teaching “honorific” languages used in U-tsang, a different region of Tibet; in Nagchu this language form is not used.
