I used several days to do a survey in a high school with Chen Yu.
the surver's aim is to find waht's the level of Kazakh students(in China) use their mother language.
the result is not so bad when we did this--but we are not sure weather the things are changed or not now.
this is a not a simple question in a nation's history and culture,besides the Languages's disappearance is becoming more and more obvious in the whole world.
what can we do to face the fact?
recording,maybe that's all.
