"Constantly studying new situations, solving new problems, summarizing new experiences, and exploring new laws," making the process of investigation a process of deepening the understanding of the Party's innovative theory, a process of maintaining flesh and blood ties with the people, and a process of promoting career development. Recently, the General Office of the Central Committee of the Communist Party of China (CPC) issued the "Work Plan for Promoting Investigation and Research in the Whole Party", emphasizing that "investigation and research are the heirloom of our Party", It is required to "vigorously carry forward the glorious tradition and fine style of the Party" and "inherit and carry forward the fine style of investigation and research conducted by the older generation of revolutionaries at the grassroots level". For the vast majority of Party members and cadres, implementing this directive requires us to learn from revolutionary predecessors and constantly enhance our ideological, political, and action consciousness in conducting investigation and research, so as to truly practice the basic skill of investigation and research. President Xi Jinping profoundly pointed out that "investigation and research are the foundation of planning and the way to success.". Looking back on the history of the Party, it is not difficult to find that no matter during the revolutionary war years, older generations of revolutionaries such as Mao Zedong, Zhou Enlai, and Liu Shaoqi understood China's national conditions and explored the path of revolution; During the period of peace building, a group of party members and cadres cannot find the "golden key" to solve various problems encountered in the process of reform, development, and construction without investigation and research, which is an important work link. The scientific practice contained in these valuable experiences still gives people wisdom and inspiration today; The ideological and working methods contained therein, as well as the moral cultivation and work style embodied therein, are also worthy of being well summarized, refined, learned and developed. An important purpose of investigation and research is to investigate the truth and overall situation of the matter clearly and create good conditions for subsequent work. This requires us to adhere to the principle of proceeding from reality in everything, listen to the truth, observe the truth, and ensure that the information we grasp is true, objective, and comprehensive. In 1961, Comrade Zhou Enlai came to Boyan Commune in Wu'an County, Hebei Province to conduct investigation and research. During this period, he organized seminars many times to encourage everyone to "just say what you have to say, and it doesn't matter if you're wrong", thereby mastering the disaster situation of Boyan Commune and the problems existing in public canteens. Also in the same year, Comrade Chen Yun came to the Xiaozheng People's Commune in Qingpu County, Shanghai to investigate. His consideration for coming here is: "This is the place where I engaged in the peasant movement in 1927. After liberation, there have been frequent contacts, and local cadres and the masses can tell the truth to me.". Practice has repeatedly proven that only by persisting in seeking truth from facts and conducting research can we ensure that the starting point and foothold for thinking, making decisions, and doing things conform to objective reality, and can withstand the test of the masses, practice, and history. In conducting investigation and research, Party members and cadres should always adhere to the principle of seeking truth from facts, adhere to the principle of Party spirit, be honest, do honest things, and be honest people, resolutely eliminate formalism and bureaucracy, and refrain from conducting research like show shows, bonsai, or skimming on water. Instead, they should "go wherever they are near or far, look at the good or the bad, and listen to the praise and criticism of the cadres and the masses" to truly understand the situation, Ensure that the process and results of each investigation and research are authentic, credible, and reliable. To learn from revolutionary predecessors in investigation and research, we must firmly adhere to the mass position of worshipping the people as teachers. President Xi pointed out that "the practice of the masses is the most abundant and vivid practice, and there is tremendous wisdom and
