On the evening of October 16, 2022, Jingxi Hotel. It was late at night. Yu Hong, the representative of the 20th National Congress of the Communist Party of China and a professor of the Army Engineering University, closed the computer, exercised her shoulders, and went to the window to open the curtains. Outside the window, the dazzling China Millennium Monument shows more poetic beauty in this day destined to be recorded in the annals of history. On this day, from morning to night, Yu Hong's heart was surrounded by uncontrollable emotions. At the moment, she felt more firm and steadfast. Professor Yu Hong is an expert in the army's expert pool of ideological and political education, and also the leader of the group of political instructors (hereinafter referred to as the "Spark" group) who preach the "Spark" theory in the Army University of Engineering. Some people regard them as "fire sowers", because along with their preaching services, the Party's innovative theory, like a spark, is constantly spreading in people's hearts, constantly igniting new fighting passions, and constantly giving birth to new chapters of progress. On November 22, 2022, in the hot atmosphere of learning, publicizing and implementing the spirit of the 20th CPC National Congress, this group was awarded the title of "Model of the Times" by the Central Propaganda Department. This textbook is full of learning experience. The pages of the book, which have been turned and wrinkled, seem to be telling the innumerable spiritual dialogues between it and its owner. The owner of this textbook is Professor Guo Youmao from the "Spark" group. "Can you see such a small character clearly?" "Not bad. The main purpose of making notes on books is to facilitate. You can link the contents of the notes naturally to the place you are talking about. It is easy to find them elsewhere." Professor Guo held his glasses and said with a smile. The eyes behind the lenses make people feel the special focus of a scholar. Professor Guo Youmao, 59 years old, has worked on the platform of ideological and political education for more than 30 years. When he was a student, he used to be nicknamed "Lao Fuzi" because he was very strict and serious in his study and life, and often looked very serious. Now, after years of military training, it is hard to feel how much "old man" temperament he has. In speech and behavior, there are more veterans' unique passions, teachers' easy-going and modest, and the casual focus. That day, in his office, we saw several similar textbooks, either published two years ago or just a while ago. In these textbooks, there are also many experiences. In his opinion, this is just a habit he has developed over the years, and there is nothing special about it. The key to theoretical preaching is the effect, and the effect first depends on the comprehensive quality of the speaker. As a speaker of the Party's innovative theory in the new era, what kind of literacy should I have? How can I improve my literacy? What is the sense of urgency to learn and the sense of awe of theory? The answers to these questions seem to be contained in a textbook full of notes. Last year, Professor Guo Youmao, as a member of the Propaganda Group for the Party History of the whole army, delivered more than 30 lectures in the organs and units of various war zones, services and arms. In life, Professor Guo Youmao has a habit of leaving his boarding pass as a souvenir every time he takes a flight, just like many of us
