A couple of weeks ago in the city of Kunshan which is between Suzhou and Shanghai there was a bit if road rage that saw one person getting killed with a rather large machete. The guy on the bike was cycling in the bus lane when the driver of the BMW decided to drive down it too and bike and BMW collided.
The driver was furious and got out his car wielding this huge machete and chased the guy on the bike, but after a bit of a struggle he dropped the machete. The other guy got hold of the knife and struck the fatal blow to the car driver and justice was served cold and swift.
No charges were laid against the guy on the bike, after all he was only defending himself.
