Xi Jinping proposed the "five-character tips" for doing a good job in investigation and research. He stressed: In conducting investigation and investigation work, leading cadres at all levels must maintain a realistic and pragmatic style.
The real situation and deep-seated problems are often covered up by appearances, and only by "piercing" can we "fish" up. Going deep into the front line and mastering first-hand materials has always been Xi Jinping's work style. In November 2011, at the opening ceremony of the second batch of students enrolled in the fall semester of the Central Party School, Xi Jinping mentioned the case of Mao Zedong's investigation into Ukraine.
