On April 8, 2013, the state-sponsored Global Times published an article entitled "Rise to the Occasion," with a photo captioned: "Dock workers and their supporters demand a 20-percent pay rise in the largest strike in Hong Kong in six years on Sunday."
These screenshots, taken on April 15, 2013, show that Sina Weibo was censoring searches for "Hong Kong Dock Workers Strike" (香港码头工人罢工), but not for "Dock Workers Strike" (码头工人罢工).
By April 20, Sina Weibo had stopped this censorship.
