Savvy, Chinese internet users have been changing their Twitter avatars to pictures of empty chairs in support of the jailed Nobel laureate. Feng 37 posted, "Living truth and paying the price, empty chair for Nobel Prize." The Chinese for "empty chair" is kong yizi- a phrase that has been banned on China's social networking sites.
Yu Jie, an activist and good friend of Liu's, spoke with ABC News in August.
"If we stop fighting because we have been intimidated by the example the Communist Party has made out of Liu, then their purpose will have been achieved. We must continue to do what he has done. We must work towards conquering our fears."
But Yu has not been heard from since November 12th. And when an ABC News crew visited his house yesterday, security forces swatted their camera away, threatening to smash it, and warned them to go away.
Yet another heavy-handed move in this repressive operation.
