From NYT article about Du Daozheng, editor of the influential political-affairs monthly Yanhuang Chunqiu and the man who secretly recorded Zhao Ziyang's recently-published (posthumous) memoirs:

Mr. Du survives such skirmishes because he is 86, wily and quietly supported by certain party luminaries. He says as many as 100 former party officials back his magazine's attempts to draw lessons from the party's buried past and nudge it toward democratic reforms. Some current officials also sympathize with the effort, he suggests. "Nobody dares close it," he said, lest that provoke a reaction from "old cadres." Last year supporters promised him, "If the magazine closes, we will take to the streets," he said.
