In 1930, when Comrade Mao Zedong was investigating in Xunwu County, he directly held an investigation meeting with the masses from all walks of life, and obtained a large amount of first-hand materials, such as the output and prices of various products in the county, the number and proportion of personnel in various industries in the county, the varieties and incomes of various shops, the amount of land and income of the peasants in various localities, and the political attitudes of various groups of people. This kind of in-depth and pragmatic style is worth learning from.

In the National Museum's "Road to Rejuvenation" exhibition, there is a precious lithograph, which is Mao Zedong's "Investigation Work" written in Xunwu in May 1930, and later the title was changed to "Against Originalism". It was in this article that Mao Zedong proposed for the first time that "there is no investigation, no right to speak" and that "the victory of the Chinese revolutionary struggle depends on the Chinese comrades understanding the situation in China". The investigation is a glorious example of our party's investigation and research in the sense of revolutionary guidance and scientific research.

The investigation was the largest social survey of Mao Zedong during the Agrarian Revolutionary War, and it was also the first time that the investigation focused on the cities. In May 1930, Mao Zedong led the Red Fourth Army from Huichang, Jiangxi Province to Xunwu. Xunwu is located at the junction of Jiangxi, Guangdong and Fujian provinces, and is the main distribution center for commodity circulation. In Mao's view, "I did not have a complete understanding of the kulak question in China, and at the same time I was a complete layman in the state of business, so I made great efforts to do this investigation." So, taking advantage of the opportunity for the troops to mobilize the masses to carry out the agrarian revolution in the nearby counties, he began to investigate the commerce of Xunwucheng.

"Which tofu is the best and easiest to sell? And which ones do the best? "Before the investigation, Mao Zedong asked a few questions to the local cadres. He led the comrades who participated in the investigation to visit 47 local shops and 94 handicraft shops, and worked together with the masses and had heart-to-heart exchanges...... Based on this investigation, the Red Army set the policy of the city as "abolishing excesses and miscellaneous taxes and protecting merchants' trade", correcting the "leftist" mistake and solving the supply problem.

As a report, the "Investigation of the Search for Wu" is divided into five parts: political division, transportation, commerce, old land relations, and land struggle. The report includes both data statistics and historical evolution; There are both industry surveys and class analyses. Specifically, the 131 kinds of foreign goods operated by grocery stores, the operation of jewelry and clock repair shops, and how to divide grain and meat during festivals in rural ancestral halls are all reflected in detail in the report. The meticulous possession of materials, scientific analysis and comprehensive research have become the most distinctive features of the "Investigation of the Search for Wu".

"Investigation and research is the foundation of seeking things and the way to achieve things. Without investigation, there is no voice, let alone decision-making. "Xi Jinping has always attached great importance to investigation and research, advocating an in-depth and realistic style, and has distinctive style characteristics. Citing the example of Mao Zedong's investigation into finding Wu, he exhorted leading cadres to do a good job of investigation and study, and they must come from the masses and go to the masses, extensively listen to the opinions of the masses, and gain a correct understanding from the social practice of the masses.

Many classes of the Central Party School have special investigation and research teaching arrangements. At the opening ceremony of the second batch of advanced courses in the fall semester of 2011 of the Central Party School, Xi Jinping gave special lectures to the students of the Party School on investigation and research. In this speech, he put forward many important judgments and work requirements, such as: Investigation and study is not only a work method, but also a major issue that has a bearing on the success or failure of the cause of the party and the people; The key to judging whether the investigation and research is done well or not is to look at the actual results of the investigation and research, the application of the research results, and whether or not the problems can be solved well.
