In early summer, at the Red Army Square in Jinzhai County, Anhui Province, the Revolutionary Martyrs Memorial Tower shone brightly in the sunlight. In front of the tower, over a hundred students from a training class at the University of National Defense Technology lined up neatly, offering a flower basket to the martyrs and reliving their oath of joining the Communist Party. Jinzhai is the central area of the Hubei Henan Anhui revolutionary base and the main birthplace of the Red Fourth Front Army, the Red 25th Army, and the Red 28th Army... "Professor Zuo Lvmin from the Political Theory Teaching and Research Office of the Jinzhai County Revolutionary Museum carefully explained to everyone. Strolling through the exhibition hall and listening to the explanations, the students seem to be returning to that passionate era of war. In the Martyrs' Hall, oil paintings depicting the heroic deeds of the martyrs are touching; In the Revolutionary History Hall, the mottled Red Army Gongtian Stele and the snow-white Yongdian Quan Stele are thought-provoking. What role did revolutionary political work play in the Red Army? What inspiration did the struggle stories of our predecessors give us? "From the Red Army Memorial Hall to the Revolutionary Museum, from the Red Army Cemetery to the revolutionary site... Through pictures and cultural relics, students look back on the arduous and stirring years, searching for answers to the lingering questions. Thinking and pursuing along the way; Accept baptism and elevate the soul. In Dushan Town, Lu'an, the students stood in front of the main map of the Sujiabu Campaign and discussed the battle process of their predecessors' encirclement and support. Although there are many enemy forces, they do not belong to each other, which leads to numerous contradictions and is one of the reasons for defeat. "" At a critical moment, our General Reserve entered the battle, forming a pincer shaped attack, and victory lies in flexible command. "" A complete victory in the battle cannot be achieved without the broad masses of the people. They spontaneously took on tasks such as transportation, guidance, rescue, and building bridges and roads, forming a strong force to overcome the enemy. "... The collision of ideas, the more the argument, the more clear the truth. Under the guidance of the instructors, the students conducted discussions and exchanges around combat policies, commander abilities and qualities, and explored the winning mechanism of the Red Army. Experience the spirit of our ancestors in the depths of history, and experience the great changes of the present and the past in reality. Walking on the rural road in Dawan Village, listening to the stories of the people in Jinzhai getting rid of poverty and becoming rich, and watching the rural scenery of the new countryside, the students were filled with emotions. A drop of water reflects the radiance of the sun. The people of Jinzhai who have lifted themselves out of poverty and fled to a moderately prosperous society are a microcosm of the great changes of the new era, highlighting the original mission of the Communist Party. "Speaking of what Dawan Village has seen and heard, student Zhang Yuanyuan said with deep emotion. Red history is the best teacher, and revolutionary sites are the best classrooms. According to Fang Hua, the director of the Political Theory Teaching and Research Department of the college, during this activity, they combined the red resources along the way to explain the theoretical points learned in the classroom for students, guiding them to learn, think, practice, and comprehend through the combination of theory and practice. After studying the two 'answer sheets' on revolution and development in Jinzhai County, I have gained a clearer understanding of the original mission of communists. "After a few days of on-site teaching, student Kong Fanqiang gained a deeper understanding and insight into the struggles of his predecessors. He said that as a revolutionary soldier in the new era, we will inherit the legacy of our predecessors, draw on the strength of progress, pursue our dreams and light up our youth on the journey of building a strong military!
