In the intertwined world of roaring machine tools and flying chalk dust, a legend about inheritance and breakthrough is unfolding. Meng Rong, a mechanical apprentice who came from a poor background, started out as a handyman carrying parts, and worked hard in the field of precision processing. With the determination of "until the Loulan is broken, it will never be returned", he has cracked the technical bones in aerospace, high-end equipment manufacturing and other fields, turning the warmth of his hands into the power to change China's manufacturing. Yan Guo gave up the excellent development opportunities and resolutely devoted himself to the battlefield of vocational education. With innovative teaching concepts and warm educational feelings, he broke the society's prejudice against vocational education and cultivated batch after batch of seeds of "great country craftsmen" that shine in the international arena.
Their story is a fierce collision between traditional skills and modern technology, an epic of vocational education's struggle to break through amid doubts, and a microcosm of the rise of China's manufacturing industry from a pursuer to a leader. When the global supply chain crisis hits, when technology blockade and talent bias loom like dark clouds, Meng Rong and Yan Guo work hand in hand to ignite the fire of hope with ingenuity and let the light of Made in China illuminate every corner of the world. This is not only a legend of the struggle of two people, but also a passionate group portrait of countless Chinese technicians and vocational education workers, witnessing how the "craftsman spirit" is passed down from generation to generation and creates brilliance in the tide of the times.
