The place where the red flag is waving ahead is the National Defense Education Exhibition Hall built by Sun Deshan, a veteran of the Chinese People's Volunteer Army. In March, in Shenyang, with the chill still lingering, following the guidance of passersby, the reporter walked into a National Defense Education Exhibition Hall located in Jiuzhan Village, Gaokan Street, Hunnan District, Shenyang City, Liaoning Province. Patriotic education base, Party history learning and education base, moral education activity practice base... The narrow courtyard corridor is filled with plaques. I heard that you built this exhibition hall at your own expense? ”Yes, I built this museum to make more people remember the history of the Korean War. ”Sun Deshan in front of me is not tall, although he is 94 years old, he has sharp ears and eyes, and is energetic. He was born in Shenyang in July 1932, joined the army in January 1949, and crossed the Yalu River with the troops to participate in the Korean War in October 1950. He suffered multiple injuries to his head, abdomen, and legs, and left a lifelong disability in his right hand. After returning from North Korea in 1955, Sun Deshan returned to his hometown to farm. I am the only comrade in our class who is still alive, and everyone else has sacrificed their lives. ”Although he took off his military uniform, Sun Deshan never forgot his past years of fighting and his comrades who sacrificed themselves in a foreign land. Speaking of his comrades who fought side by side on the Korean War, two tears silently slid down his cheeks. Every year around the Qingming Festival, Sun Deshan goes to the Shenyang Martyrs Cemetery to pay tribute to his comrades in arms. On the eve of Qingming Festival in 2002, Sun Deshan, who was sweeping tombs, was surrounded by a group of high school students who came here to study and asked him to tell the story of the Korean War. When chatting with them, I found that many students were not very familiar with the history of the Korean War, and knew very little about the fighting heroes in the Korean War. ”Sun Deshan recalled. Since then, Sun Deshan has had the idea of building a theme exhibition hall for the Korean War to help more people remember this period of history. From then on, he began to collect information, photos, and cultural relics related to the Korean War. If his savings are not enough, he will tighten his belts, pick up junk, and sometimes go to the construction site to do odd jobs. Faced with the confusion of his family and neighbors, Sun Deshan always answers like this: "My comrades have sacrificed their lives for the country and have not come back. I must do something for them." In 2009, Sun Deshan took out more than 80000 yuan of savings and used the more than 1000 exhibits he raised to build an exhibition hall in his own yard, which was open to the public for free. The students from the surrounding schools came and their eyes turned red after listening to the story; The officers and soldiers of the stationed troops arrived and saluted Sun Deshan in unison after watching it; Visitors from all over the country left messages to pay tribute - "Respected Grandpa Sun, here I not only learned about the history of the Korean War, but also learned about the noble character of soldiers. I pay tribute to heroes and you." "The great Korean War, the great spirit of the Korean War, and the heroic soldiers of the volunteer army are worth remembering forever." "With the increasing number of visitors, Sun Deshan is even busier. In addition to his daily voluntary lectures at the exhibition hall, he has also been hired as an off campus counselor by several schools and invited to spread the word on campus. In 2023, with funding from a charity organization, Sun Deshan's education museum was renovated and expanded, and now it has become a well-known memorial site for the Korean War. As long as we remember, they will always be alive. ”At the moment of parting, holding Sun Deshan's calloused hand, the reporter suddenly understood that the exhibition hall in front of him was the "monument" erected by this veteran for his comrades?
