On the afternoon of March 11, the reporter saw an astonishing scene at the Bulong Highway in Hebei Village, Longgang District of Shenzhen: a man in black held a shiny kitchen knife and rushed to a man in gray. The man in gray couldn't avoid him, and was cut under the left armpit with blood flowing. Subsequently, the injured man held a stone and scolded at the knifeman. The knifeman was full of anger, pointing his finger and cursing loudly, wanting to rush forward again. Fortunately, a woman in blue hugged the man in black tightly.
