Why did Mao launch the Great Proletarian Cultural Revolution?

The Great Proletarian Cultural Revolution was China’s answer to this question.
Was the Great Proletarian Cultural Revolution a power struggle between the elite behind a façade of an imaginary mass movement?
On the contrary did Mao Zedong launch the Great Proletarian Cultural Revolution in order to keep China on the socialist path? Or did he launch the revolution to restrict the class differences bequeathed from the Confucius system of the old society and thereby stave off any Imperialist ideology and prevent a capitalist class from developing within the Socialist society Mao yearned to create, in a comprehensive attack on the four elements found within Chinese society of ‘old customs, old habits, old culture, and old thinking’ (Spence, 2013, 543). Dependent on perspective, there are various outlooks as to why Mao Zedong launched what was to be known as the ‘Great Proletarian Cultural Revolution’. Historians and Scholars are often divided on the reason. The four elements were an ethical and philosophical system, which had evolved from the teachings of the Chinese philosopher Confucius, into the state ideology of China.

The big is beautiful approach of Stalin contributed a lot of elements to the Leap Forward although there were slight differences in parallel to Stalin approach. “a desperate Maoist attempt to break through economic constrictions and to reassert the centrality of revolutionary change-stood in opposition to the Soviet Union’s more cautious approach to economic development and mass mobilisation” (Spence, 2013, 523)
The general consensus of increasing socialism via an economic growth was introduced, therefore if the population could have credence in and be enlightened via Mao ideology and the state’s resources used more effectively, this would result in simultaneous growth of industry and agriculture. This approach saw the party adopt a mass mobilisation of the proletariat and organisations.
Mao’s decision to focus on the Great Leap Forward was based in
