After the radical Cultural Revolution erupted in 1966, many Communist revolutionaries who had spent time in Kuomintang prisons, including Zhang's former prison mates Bo Yibo and An Ziwen, were denounced as traitors (known as the "61 Renegades") and persecuted. Zhang was posthumously labelled a traitor, and his ashes were exhumed and discarded. His name was cleared after the Cultural Revolution ended in 1976.
