When somebody defected from the Czechoslovak Socialist Republic, his/her relatives would be punished by being fired from good jobs and forbidden to take new ones; usually they had to do some harder and worse paid work. Unless they were members of the Party; in that case, their position was a bit shaken by a defection in family, but they usually could survive in place.

And yeah, their kids were either banned from studying interesting majors, or at least their education became more complicated.

This even concerned highly qualified people such as surgeons.

That is why we should have treated ccp as Soviet Union.

If CCP is as you described, and Peng Shuai worry about her family, she wouldn't speak in the first place. There was nothing happening for her before she made the post online.
