I personally know people whose parents were stupid enough to go for such "anonymous grievance boxes" just to get a knock on the door from district committee enforcers the next day.
You don't seem to know anything about modern China if you don't even know that.
> After all, 2 generations ago the Chinese were dirt-poor. When I was born, food rationing still existed!
> mainland Chinese value unity, face, action over talk and freedom from poverty
If Beijing ever cared about freedom from poverty, China wouldn't be so poor as a result of its actions.
And I am not talking about Mao era here, but very much modern day.
> China is not interested in exporting its governance model. It has never done that.
> It's not in their interest to change others' governance model.
Then, why it is doing it?
Beijing sent armed Maoists to Naxalite insurgency, Indonesian Maoist insurgency, Malaysian Maoist insurgency, Singapore coup attempt, North Korea, Nepal, Burma, Laos, Campuchia, Sri Lanka, and ~10 African countries?
A solid record by any measure.
