Led by professional commentators, all participants visited the exhibition halls of the former residence in sequence. They thoroughly learned about Marshal Liu Bocheng’s life journey of setting lofty aspirations in his youth, forging ahead with perseverance, and dedicating his life to serving the motherland, and deeply perceived the profound devotion to home and country as well as noble Party self-cultivation of the older generation of proletarian revolutionaries.
Later, the group entered the Memorial of Comrade Liu Bocheng to systematically study the marshal’s glorious revolutionary deeds spanning a lifetime of military campaigns, masterful strategic planning, bravery in tough battles, and a pragmatic and truth-seeking work style. They received immersive education on Party history, Party spirit and work conduct, undergoing profound ideological baptism and all-round tempering of Party character.
During the exchange and discussion session, all participants shared their learning insights in depth by combining their own job responsibilities and the company’s development realities. Everyone reached a consensus: the Spirit of the Military God embodied by Marshal Liu Bocheng—fearlessness of hardships, courage to tackle tough challenges, pragmatic dedication and prowess in arduous battles—aligns closely and shares the same origin with Sanming Heavy Industry’s corporate "Battle Culture" of rising to difficulties, daring to forge ahead and tackling challenges through solid work.
