The Great Leap Forward was a colossal failure on the part of the Chinese Communist Regime.
Explanation:
Mao Zedong's scheme of the Great Leap forward relied on the labor on common land and ablution of private property in China.
The workers were to make the country into an industrial powerhouse to bring general prosperity in the nation.
