This type of attack is impossible in China. At my old high school, the school was gated, and there were security guards were outside the school doors. The school lead out to the local university, which was again, gated with guards.

Thus, external attacks like this, where the attacker was not in the school would prove to be impossible. This is why we heard of kindergarten attacks a few years ago, the outside madman can't really attack students at high schools, so they attack kindergartens without security.

As for internal attacks within the student body, a significant amount of students live in residence on dorms at the middle school to high school level in which it would be impossible for them to attack the school.

Now for the rest of the students, I've identified a few more reasons, why attacks like this are far less common. If media (video games, gangsta rap, violent movies, etc) do make you more violent, than Chinese students have little time to actually consume any of it.

Also, a large number of attacks are ideologically motivated, and again, that won't happen. All schools have political science teachers. Teenage anger and rebellion? what is that? It surely never happens in China.
