China does advertise the success of their policies, but I don't think they do it nearly as often as they should.

I think some of the reasons might be because in Chinese culture, and the style of governance of the CPC, is "actions speak louder than words" and the government doesn't want people to become complacent with success or think that the CPC is always right or has the answer, or appear arrogant or all-knowing.

I think that even though Mao did alot of good, China is very reluctant to take influence from him and the Cultural Revolution, for obvious reasons. Not to say that China doesn't take any influence or lessons whatsoever from the classical Maoist era, though.

I also think that even though China does an excellent job at filtering out anti-communist and sinophobic propaganda, the government feels that no matter how well it presents counter-arguments against malicious lies and slander, the mere fact that the Chinese government is addressing things will make an unfortunately surprising number of people outright reject, deny or be skeptical of their claims.

Given how tech-certified and super-rational the CPC is, sometimes I think that they think that most Chinese people are just like them, and underestimate just how powerful irrational and emotional arguments can be to people who don't know any better, aren't politically involved, or don't research every single question about every topic they have. And there are only so many hours in a day.
