The blue sky of the motherland will not be forgotten - to understand the spirit of "serving the country by air" of Shen Fei's workers, President Xi wrote back to the members of the "Luoyang Youth Commando" of AVIC Shen Fei on November 12, encouraging them to continue to carry forward the spirit of "serving the country by air", to think together, to make efforts in one place, to climb bravely in promoting the self-reliance of aviation technology, and to take an active role in promoting the high-quality development of aviation industry, We should strive to be a good youth in the new era with ideals, courage to take on responsibilities, ability to bear hardships, and willingness to struggle, and make new contributions to building a socialist modern country in an all-round way and promoting the great rejuvenation of the Chinese nation in an all-round way. After receiving the reply from President Xi, Shen Feijun's workers were very excited and deeply felt the great responsibility. In combination with the recent study, publicity and implementation of the spirit of the Twentieth National Congress of the Communist Party of China, everyone said that we must keep in mind the earnest instructions of President Xi, continue to work hard, devote ourselves to serving the country, and lift up the war hawk with the strength of youth, so as to make new and greater contributions to building China into a world science and technology power. Entering the J-15 aircraft assembly workshop, the roar of the machine was endless, and it was a busy scene. Under the eye-catching slogan of "holding the national property in one hand and the life of comrades in arms in the other hand", "all for fighting effectiveness, all for service fighting effectiveness", the staff of Shenyang Aircraft Co., Ltd. focused on operating equipment on the assembly line. "Compared with pilots flying eagles, military workers rarely appear in the spotlight." Sun Cong, the chief designer of J-15, said that they are the shadows of "knife point dancers" and the heroes behind the heroes. The blue sky of the motherland will never forget that these ordinary military workers have worked hard for China's aviation industry with their blood and youth, and accumulated the strength to build a strong military in silent years. A photo testifies to the heroic feat - everyone is a drop of water, and the sea with great power gathered together. On November 23, 2012, China's shipborne aircraft J-15 successfully landed on the "Liaoning Ship", and China's aircraft carrier development ushered in a historic breakthrough. While everyone was excited about the J-15's perfect landing, Luo Yang, as the commander in chief of the fighter plane development site, fell on the triumphal road of the "Liaoning Ship". After the death of Luo Yang, the media found it difficult to find the video materials of the hero who burned his life for the aviation industry when interviewing his deeds. There is only one photo of Luo Yang and the "Liaoning Ship". At that time, Luo Yang's old mother made a request to Shen Fei: "The child is usually so busy at work, I don't know what he is busy about. Can you sort out his achievements and honors for me?" Hearing this sentence, everyone present was moved. Shen Fei Company made a commemorative album for the hero's mother. The title of "model of serving the country by air" and the "golden award of serving the country by AVIC Aviation"... Looking through this album, the old mother saw a "strange and familiar son" - it turned out that his son had done so many important things and won so many awards in recent years. "The sky has not left our footprints, but the birds have flown." His parents have never seen what Luo Yang has done, and his wife and children have never known it.
