I'm guessing it is a "hand tuned" search result tweak because just appending "china" returns a few images:

(For those who don't see results, this is my screen grab of the above at 18:12 UTC : https://imgur.com/a/3tzPV49)

Also, "Tiananmen Square massacre" still returns some image results:

https://www.bing.com/images/search?q=Tiananmen+Square+massac...

Therefore, the tweak for "tank man" doesn't seem to make any sense since all the other phrases to get to the same sensitive topic are not suppressed.

Adding "tiananmen square" to "tank man" does return the photo as the 3rd result: tank man tiananmen square

Also, the misspelled version of Tianenmen that I first used worked as well.

OTOH "tank man tiananmen" is also censored. It's pretty clear that there are some specific queries being mishandled here.
