The honor wall of a sailor team of a navy detachment in the Northern Warfare Zone is equipped with four theme plates of "loyalty", "victory", "sunshine" and "peace". It comprehensively displays the sailor team's struggle history, fine traditions, meritorious deeds and honors in the form of physical objects, pictures, poems, paintings, Paper Cuttings, etc., and builds a lively classroom to strengthen the struggle spirit and stimulate the striving force. The 12 big characters on the honor wall of a certain crew of a naval detachment in the Northern Theater Command shine brightly, with the words "indomitable, invincible in all battles, and refined into steel". The leader of the crew told reporters that this is their "three hundred spirit". The text is surrounded by scattered waves, symbolizing the determination and action of the sailors and soldiers to promote the "Three Hundred Spirit", to break through the waves and defend the motherland's borders. "Since its establishment only one year ago, Sergeant Shen Guoxiang has completed installation, sea trials, ship delivery, and enlistment, and has successfully carried out multiple tasks such as long-distance combat patrols, exercises, and weapon equipment testing. Strengthening our skills and advancing towards battle has always been our unchanging pursuit..." At the educational activity site with the theme of "Inheriting the Red Gene to Forge Underwater Pioneers," Sergeant Shen Guoxiang stood in front of the wall of honor, telling his comrades the glorious history of the crew. On the wall of honor, there are medals and photos recording the extraordinary achievements of the sailors' team, namely, the exemplary organization of the Navy's "four irons", the "exemplary organization of war preparation", the "exemplary organization of talent building", the "national outstanding Communist Youth League cadres", Zhao Yue... A model is a flag and an example is a benchmark. On the anniversary of the establishment of the submarine unit every year, the crew invites the older generation of crew members to tell stories of their struggles and lead the new generation of officers and soldiers to relive the turbulent times. In front of the Honor Wall, the exchange and dialogue between new and old submarine soldiers have increased the enthusiasm of officers and soldiers in the new era to cherish honor and strive for progress. There are still some gaps on the honor wall of the crew. Explanator Liu Yisheng introduced that keeping the Honor Wall in an "incomplete" state is to motivate officers and soldiers to shoulder the red flag and compete for honor when they see it, in order to win more honors with better results. Whenever carrying out major tasks, the crew will organize education and mobilization, and the officers and soldiers will come to the front of the Honor Wall to sign oaths and challenge themselves. After completing the task, they promptly selected advanced models and their touching deeds that emerged from the task, and displayed them on the wall of honor. "Promote the deeds of exemplary soldiers and carry out the activities of striving for excellence, so that officers and soldiers can have models, learn from them, and strive for goals." The leader of the submarine crew said that they hope to take various measures to create a strong atmosphere of work and entrepreneurship, strengthen the spirit of progress and struggle, and enable officers and soldiers to focus all their energy on preparing for war, continuing to write the glory of the submarine soldiers in the new era.
