"At 10:30 on May 18, 1980, the instrument cabin of the carrier rocket splashed down, and I salvaged the helicopter at full speed to the target, passing through the thick cumulus clouds that are difficult to bypass on the route..." In early December, Lv Yunxing, a retired cadre and a member of the volunteer propaganda group of the Qingdao Retired Cadres Service Center of the Armed Forces in Shandong Province, walked onto the podium of Mount Huangshan Primary School to tell the story of his participation in salvaging the instrument cabin of the carrier rocket. Give full play to the residual energy of veterans and tell the story of national defense well The leaders of the center introduced that they, together with Wangtai Street, fully utilized their own advantages and selected more than 80 retired military cadres with profound theoretical knowledge and rich military experience to form a volunteer preaching team. They went to local primary and secondary schools and communities as planned to preach national defense stories. To ensure the effectiveness of the presentation, they strictly review the content of the presentation, cooperate with the members of the presentation team to search for information, edit relevant short videos, and create teaching materials. The author saw in Mount Huangshan Primary School that Lv Yunxing, with the title of "Inheriting the Red Spirit, Reviving the Power and Having Me", combined with his 33 years of flying in the sea and sky, more than 20 times of major tasks, and more than 2700 hours of safe flight experience, guided students to strengthen their ideals and beliefs, study hard, and contribute to society when they grow up. I used to only learn about heroes in movies and TV dramas, but I didn't expect heroes to come to us Some senior students expressed, "Listening to Grandpa Lv's story of struggle, I am particularly moved. I must study hard, grow up, and serve the country." Since the beginning of this year, volunteer preaching teams have visited schools and communities more than 80 times, with an audience of over 30000 people. (New Society)
