On March 1, 1948, the Communist Party of China issued an intra-party directive "On the Question of the National Bourgeoisie and the Enlightened Gentlemen". At the same time, it successively issued a series of directives such as "On Several Important Issues in the Current Party's Policy", "On the Policy of Industry and Commerce", "Correcting the" Left "Error in the Propaganda of Land Reform", in order to correct the "Left" bias such as the overbroad attack on land reform and party consolidation, the attack on national industry and commerce, the phenomenon of random fighting and killing, and the hasty resolution of the land issue in the newly liberated areas.
