I hope this isn't an endorsement of serpentza or laowhy86, bitter expats with middle school mandarin proficiency flunking out of China are not insightful sources. There are millions of Chinese diaspora who lived in both Chinese and western cultures with much more useful things to say.

Here are recent studies on how domestic and foreign Chinese propaganda works.

How the Chinese Government Fabricates Social Media Posts for Strategic Distraction, not Engaged Argument https://datasociety.net/events/databite-no-94-jennifer-pan/

Beyond Hybrid War: How China Exploits Social Media to Sway American Opinion https://www.recordedfuture.com/china-social-media-operations...

Overlapping findings of both reports is that Chinese propaganda focus on overwhelmingly positive, benign messaging i.e. it placates and downplays instead of argue, attack or antagonize. Both also suggest 50c doesn't operate outside of China. Again, I wouldn't be surprised if Chinese foreign influence has expanded. I hope it would at least be closer to meme-able Baghdad Bob than whatever low-effort campaign that twitter alleges.
