Forty-seven years ago today, on September 16, 1978 (August 14, 1978 in the lunar calendar), Deng Xiaoping criticized the "two things" in Jilin. On September 16, 1978, during his inspection in Jilin Province, Deng Xiaoping made a speech while listening to the report of the Standing Committee of the Jilin Provincial Party Committee and criticized the "two things" again. He said that how to hold high the banner of Mao Zedong Thought is a big problem. Now many people inside and outside the party, at home and abroad, are in favor of holding high the banner of Mao Zedong Thought. "Two things" is not really held high, it is a formalist high, it is a false high. If this continues, it will damage Mao Zedong Thought. The basic point of Mao Zedong Thought is to seek truth from facts, that is, to combine the general principles of Marxism-Leninism with the specific practice of the Chinese revolution. The essence of Mao Zedong Thought is the four characters "seek truth from facts". We hold high the banner of Mao Zedong Thought, which means that when dealing with various principles and policies, we must adhere to reality. Deng Xiaoping also pointed out that the "two whatever" viewpoint is incorrect, and if Mao Zedong were alive, he would definitely not agree.
