Yes, you will hear all kinds of opinions when you go outside of China. But will you be able to hear any different voices inside China? Nope, thanks to CCP's top of the world censorship and oppression for different opinions. Although CCP is lamenting the spread of the corruption among its leaderships and asking for public monitoring to help stopping the spread of the corruption. But if you don’t let people speak, how could you expect transparency or public monitoring? If there's no relative freedom of speach, how can you expect people to speak up and to help stop the corruption? A corrupted party will eventually lose public’s trust and CCP knows it too.
