Fake protest for Western consumption
I do not think that it is a fake protest, but rather the displeasure of most Chinese citizens chafing under his rule.
As explained by a former missionary to Wuhan, most government officials simply do not share their opinions on Xi, or on any official at all.
If they support the official and he is overthrown, then they may be at risk personally.
If they seem too enthusiastic, then they will be perceived as being an ally of the official.
Whomever this person is, knows what the CCP army and CCP police supporting Xi will do. He is disappeared.
And the people that were associated with him will be questioned.
Fake poster - you.
