Once safely outside of the PRC's reach, it's trivial to move the wealth around using corporate entity ownership (among other methods).
It's not trivial to move capital around using foreign corporate entities, when they track all of your communication within China. If they even so much as get a hint of that going on, and it bothers them in the least, they can do anything they like to you at that point. The hint of suspicion is more than enough, if it suits them. Being able to move capital around is meaningless, if you're not entirely physically free yourself as well.
Your scenario is only a sure thing, if you've escaped your capital and everyone you care about.
Think in terms of nobility: what’s more important, your head or your dynasty?
