You seem to be circling the issue. Corruption can mean anything from taking bribes to exerting influence that is outside Xi’s interests.
Or in authoritarian regimes it often means "stole from the party". As long as you only steal from the poor and give the proper bribes up the chain you are in no danger in most corrupt societies. Except possibly in the rare occasion where your corruption causes a disaster that embarrasses the people above you in the hierarchy.
Far too often when you see stories about how someone was persecuted for corruption it boils down to "he stole from rich people".
And far too people are aware that Xi is extraordinarily corrupt..
"Similarly, Xi’s siblings, nieces, and nephews held assets worth over $1 billion in business investments and real estate"
