Authorities have tightened security around high school and college campuses in the wake of demonstrations in support of Tibetan language.Several hundred students and teachers from high schools in Chentsa county, in Qinghai's Malho Tibetan Autonomous Prefecture, took to the streets on Oct.24 in support of the continued use of Tibetan language in local schools.And in Rebkong (in Chinese, Tongren) county, security personnel prevented reporters from entering schools on Monday, as police and plainclothes security officials were on guard outside minority middle schools and high schools in the town.

A group of 300 teachers in Qinghai had sent a letter to the authorities appealing to stop any implementation of an only-Mandarin Chinese language policy.

Chinese authorities have already dispatched large numbers of security personnel to Tsolho and Rebkong, after the demonstrations spread there on Friday.
