【明報專訊】LIU XIA, the widow of Nobel Peace Prize laureate Liu Xiaobo, has regained her freedom at long last and arrived in Germany prior to the anniversary of her husband's death. Liu Xia did not break any laws. But she was deprived of her freedom of movement for a long time, was put in de facto house arrest for eight years and endured mental torture. The inhumane treatment she received was in obvious violation of the idea of "governing the country in accordance with the law". Now that Liu Xia has regained her freedom, a tragic chapter of Liu's family has closed. But by no means can the authorities wipe this ignominious taint from history.
