Hoang Gia Duc, a 77-year-old resident of Ha Long, Quang Ninh, recently received a document that rekindled memories of his harrowing experiences during the Vietnam War. This document, which he had not seen for over fifty years, serves as a powerful reminder of the sacrifices made during a tumultuous time in history.

In 1973, Duc was among thousands of individuals sent from North Vietnam to support the southern regions in their fight against American forces. The government had organized a comprehensive mobilization of party members, doctors, teachers, and cultural workers to bolster the revolutionary movement and maintain social life in liberated areas. Due to the sensitive nature of these missions, all personnel were required to leave behind their personal documents and belongings in the North.

Born in Quang Yen, Duc was exempted from military service due to his brother's involvement in the Quang Tri battlefield. After completing eighth grade, he was sent to China to study film projection technology and later worked at a state-owned film company. In 1972, he married Bui Thi Hien, who worked nearby. Just days after the birth of their first daughter, Duc received orders to depart.

His journey began with training in Ha Tay, followed by a mission in the southern region, where he faced the brutal realities of war. Duc's team was responsible for managing and building film projection units that served as cultural soldiers, bringing films and news from the North to the South. These screenings were often held in border areas, using lightweight equipment to reach communities still under enemy control.

Despite the dangers, including ambushes and harsh living conditions, Duc remained committed to his mission. Tragically, he lost a colleague, Le Dai Su, during a surprise attack disguised as civilians. Their mission was fraught with peril, but Duc persevered, believing in the importance of his work for the nation.

After the war, Duc returned to manage cultural activities in the region, but the emotional toll of his experiences lingered. Recently, a historical archive center in Quang Ninh discovered his long-lost service record, which was returned to him as a gift in honor of the 79th Anniversary of War Invalids and Martyrs Day. Duc expressed that while he may not possess physical mementos from his past, the document serves as a priceless reminder of his journey and the sacrifices made during the war.
