When Anna's fans recovered their composure, they realized that something was wrong. They couldn't put up with this.
And so the live audio feed featured a face-off between Anna's fans, who appeared to have squeezed every last ounce of energy left in them and cried hysterically, and the mayhem brought on by Fang Zhao's fans and the photographers.
Neutral parties wondered who they should support. Forget it, I'll just chant what the person next to me yells.
In an atmosphere like this, one would feel bad not taking a side.
Eventually, the mood hit its ultimate climax. At that point, words became meaningless. A simple cry of "ah" sufficed.
So shouts of "Fang Zhao" and "Anna" eventually blurred into one loud chant of "ah."
