Around noon on May 4th, 2012, Song Ze received a phone call in which the caller said someone who had been put in a “black jail” [an illegal prison used mostly to detain petitioners, disempowered citizens who went to Beijing to file a complaint about his/her local government] hoped for help, and asked Song Ze to meet him in the lobby of Beijing South Railway Station at 2 o’clock. Same as ever, Song Ze did not hesitate to respond.
