What did Mao Zedong create that made agriculture more efficient?

Mao Zedong implemented the Great Leap Forward in 1958, which aimed to rapidly transform China from an agrarian society into an industrialized socialist state. This campaign included the establishment of collective farms, known as People's Communes, where agricultural production was intended to be more efficient through communal labor and resources. However, the initiative led to widespread mismanagement, resulting in significant agricultural failures and contributing to a devastating famine.
