AFP The ruling Chinese Communist Party (CCP) has allowed public access to the grave of Jiang Qing, former member of the Gang of Four and widow of late supreme leader Mao Zedong, ahead of its centenary on July 1. “This was sent to me by a friend mainland China, and I am forwarding it here," former CCP Party School professor Cai Xia, who now lives in the United States, said via her Twitter account on April 5, the traditional grave-tending festival where people make long journeys to honor the dead. She said the move was in contrast with the state security police detail that guarded the grave of late ousted premier Zhao Ziyang, who fell from power after opposing the use of military force against unarmed civilians in 1989.
