In December 2012, this blog noted that Sina Weibo had begun censoring searches for "Xinhua PS," apparently as a result of Internet users in China speculating that Xinhua had published a photo that had photoshopped Li Keqiang and several others into a photo. See http://blog.feichangdao.com/2012/12/web-sites-censor-speculation-that.html
These screenshots show that, some time after this allegation began to circulate, Xinhua removed the photo in question.
