At least a thousand Tibetan high-school students have protested against the increasing use of Mandarin in their lessons, at the expense of their Tibetan.
Between 1,000 and 7,000 students in the town of Tongren, in Qinghai province, took to the streets on Tuesday, chanting slogans against the replacement of Tibetan with Mandarin Chinese.
According to Radio Free Asia, which obtained fuzzy video images of the protest, marchers from six schools in the area took part. Many of them were wearing their blue-and-white school tracksuits.
