Let me put it bluntly. There is a closeup of a woman with only half a head. It comes as a surprise as the first images are not as bad, and the article's content draws you in. I had to stop there even though I wanted to continue reading.
However, you do correctly point out how this article appears to draw people in and then goes for maximum shock effect. I'm sure that whoever created this article did that on purpose. Even if the cited numbers happen to be accurate, this kind of tactic is rather typical for propaganda. The same can be said about producing "facts" that are either hard or impossible to verify.
To be clear: I am not saying that this is propaganda, but it does at least raise a few red flags about potentially being just that. Further research needed.
EDIT: to be even more clear: I have no doubt that the CCP have committed horrible crimes. But that will not make me just believe whatever somebody might write about it.
