In April, Deng began the political rehabilitation of those who were formerly labeled "rightists" and counter-revolutionaries, a campaign led by Hu Yaobang that pardoned the wrongly accused, restoring the reputation of many party elders and intellectuals who were purged during the Cultural Revolution and other campaigns going all the way back to the Anti-Rightist Movement in 1957. Prominent politically disgraced people including Peng Dehuai, Zhang Wentian, He Long and Tao Zhu were given belated rank-appropriate funerals at the Babaoshan Revolutionary Cemetery. Liu Shaoqi was given a large state funeral in May 1980, when the country was asked to mourn the former president eleven years after his death. During this time, the CCP also established rules for an orderly succession of state and government leaders. Deng Xiaoping proposed mandatory retirement ages despite some protests from party elders and also guidelines were put in place that CCP members who lost their posts or were removed from office could not be jailed or subjected to physical harm. In this regard, Deng borrowed much from Soviet leader Nikita Khrushchev when the latter had ended Stalin's terror state and established the practice of using more peaceful methods to dispose of his political rivals. To that end, CCP figures such as Hua Guofeng were merely demoted to unimportant posts, but otherwise retained their party membership and state pension.
