In page Deng Xiaoping:

"

Deng quoted the old proverb "it doesn't matter whether a cat is black or white, if it catches mice it is a good cat." The point was that capitalistic methods worked.[1] Deng worked with his team, especially as Zhao Ziyang, who in 1980 replaced Hua Guofeng as premier, and Hu Yaobang, who in 1981 did the same with the post of party chairman. Deng thus took the reins of power and began to emphasize the goals of "four modernizations" (economy, agriculture, scientific and technological development and national defense). He announced an ambitious plan of opening and liberalizing the economy.[2] On Deng's initiative, the CCP revoked the position of Chairman and made the General Secretary the ex officio leader of the party.[citation needed]
