Wang Hongwen, who helped lead China's bloody Cultural Revolution as one of the infamous Gang of Four, has died of a liver ailment at age 58, the official Xinhua News Agency reported Tuesday. Mr. Wang's youthful bravado, good looks and radical politics caught the eye of Mao Tse-tung's wife, Jiang Qing, in 1967 and led to his meteoric rise from factory worker to Communist Party vice chairman. He fell from power with Mrs. Jiang and other gang members in 1976, less than a month after Mao died. He was sentenced to life in prison. Xinhua said Mr. Wang died Monday of a liver ailment, but gave no details.
