During the Tianeman Square incident, troops were brought in from regions far away from Beijing precisely so they would have very little problem with shooting 'chinese'.
China likes to present to the world that it is one big happy family, but that really isn't true. The Hans don't much like the Manchurians who don't much like the Mandarins, etc etc. The CCP stays in power largely by playing one group off the other and trading in favors to the ruling classes.
Believe me the CCP would gladly starve 1/10th of their population to death in order to hold on to power. They've done it before and they won't hesitate to do it again if they must. All that matters to them is The Party.
The CCP has convinced itself that without the Party there is no China. That is a very dangerous mindset indeed.
