"No matter what "A black cat is a good cat if it catches mice." This is a famous saying by Deng Xiaoping, which is also a popular summary of Deng Xiaoping Theory. As for the origin of this sentence, there are different opinions. Two pieces of evidence are now provided.

First, this is a Sichuan proverb. There is a saying in Sichuan: "Yellow cat or black cat, as long as it catches mice, it is a good cat." Deng Xiaoping was a native of Sichuan, so he should naturally know this sentence. Deng Xiaoping and Liu Bocheng had been fighting for many years during the war years, and Liu Bocheng often liked to say this saying. Deng Xiaoping had a profound influence on it.

Second, this is a sentence from "Strange Stories from a Chinese Studio". There is this text in the third volume of the manuscript of "Strange Stories from a Chinese Studio", "Expelling Monsters": "Yellow raccoon and black raccoon, the one who catches the mouse is male!" Here, the raccoon is also a cat.

This sentence, translated into vernacular, is: "A yellow cat or a black cat is a good cat if it catches mice!" According to Ma Ruifang's article "Deng Gong and Liaozhai": "According to Zhuo Lin, Deng Gongxi When I read "Strange Stories from a Chinese Studio", I not only read it when I was in Beijing, but also asked the staff to make loose-leaf books when I was out, and read a few chapters in my spare time." It can be seen that Deng Xiaoping loved reading "Liao Zhai" and should have known this sentence.

On July 7, 1962, when Deng Xiaoping met with all the representatives of the Seventh Plenary Session of the Third Central Committee of the Communist Youth League, he said: "What form of production relations is the best? I am afraid we must adopt such an attitude. .

That is, whichever form is easier and faster to restore and develop production in which place; whichever form the masses are willing to adopt should be adopted, and what is illegal should be made legal. Get up." Then he said a saying: "It doesn't matter if it's a white cat or a black cat, as long as it catches mice, it's a good cat."
