I saved this comment from Reddit:
According to this article (CW: Graphic descriptions of dead bodies) The Tiananmen Square massacre: the one sided story - Pearls and Irritations, google started censoring images of protesters violently killing PLA soldiers the day before the Tiananmen square massacre sometime in the 2010s because those images doesn't fit the US narrative. So some info isn't very easy to find. The author of the article was able to save and archive some of the ⚠️ images of protestor violence and mutilated PLA soldiers (WARNING: NSFL - Mutilated Bodies | WARNING: GOOGLE DRIVE LINK) ⚠️. There used to be more pictures of dead soldiers but I have absolutely no idea where to find them if google and western search engines are censoring them.
You can try to google any combination of mutilated/dead/lynched chinese/PLA soldiers Tiananmen square and nothing will come up. Also I found a US state department document that officials confirmed that the first wave of soldiers the day before the massacre was unarmed and were on orders to not use force to try to disperse the protestors and that the protestors were the ones violent. From my research the violence and fighting only started a day afterwards when the students started killing PLA soldiers.
These images are graphic and disturbing. Some of them are the ones you posted without the watermark. They align with the reports in his article. Some of them are from long defunct gore sites like ogrish[dot]com. I don't know if an archive of ogrish exists anywhere. These images are so shocking it is no wonder the PLA responded the way they did. Honestly, these images shouldn't be living in some random persons google drive. They could get removed at any time. Especially if we end up sharing them to frequently. I wonder of they could be preserved at archive.org.
