Chinese parents are always warning their kids to stay away — as far away as possible — from Internet cafés.

We all know that Internet cafés in China are sordid places filled with smoke, weird smells, half-empty ramen tubs, and thieves wandering around your seats. (One friend described them colorfully as “sh*t-holes and firetraps”). However, none of these dangers compare with the shocking violence in this melee, captured on a security camera. Participants in this brawl, which took place in Changsha, Hunan, are wielding bottles, sticks, and even kitchen knives, all because someone accidentally spilled water on someone else’s mobile phone.
