Abstract: The “Great Leap Forward” at the end of 1950 s and beginning of 1960 s is a movement launched by the Chinese communist party. The decision and policies of the movement are proved wrong. In the execution of the movement, the deviations as mechanical execution, savage execution, expand execution, etc. are widespread, which brought serious damages to the people and the country. In the analysis of the policies in the movement, we hope to show some enlightenments to our party in the decision-making.
