As someone who's been to China, this is a little on the bizarre side. University students were once held in high esteem, and it was everyone's goal to send their kid to university. It was a sign of being an intellectual, and worthy of praise. That a group of 10 men would attack students in a university is extremely troublesome.
Moreover, the degree to which social cohesion is fraying in China will likely lead to more draconian efforts to create social cohesion, i.e. more human rights abuses. In particular, censorship of media is about to get a lot worse, and expect more hacks into emails of those who speak up.
