Laoshan,
Now it is the begining stage of Culture Revolution, i.e., fighting in words. Fortunately, we are in US and it is unlikely Chinese will fight in fists in America. In China, we may soon see fist fightings.
In any sense, it is clear that now China is in RED terror under Xi Jinping. No matter fist fighting happens or not, it is Xi Jinping's version of Culture Revolution.
