I have seen this in my Twitter stream today, and I can't really believe it - does the PRC state media really try to re-brand the photos as a "celebration"?? https://twitter.com/libdave/status/516281577001590785 Then again, I think that's pretty much what they did with pictures from the Taipei student protests earlier this year...

This is a picture of a separate celebration event from the 26th (Friday). It's part of the celebration events leading up to 1st Oct.
