"Mountains and Rivers" tells the story of Lu Yunshu, a textile industrialist who inherited his father's business from 1921 to 1938. In the troubled times when the national industry was in decline and invaded by foreign powers, he used technology to serve the country and save the country through industry. Lu Yunshu's growth is not a linear "upgrade", but every choice he makes in the conflict between technical ideals, emotional ties, and responsibility for his family and country. Her "big heroine" quality is not that she is born strong, but in the process of losing her father, losing her factory, and possibly even losing her life, she gradually realizes the weight of the four characters "" - the loom turns not only the yarn, but also the pulse of civilization maintained by the most primitive "spinning and weaving" of a nation at the time of survival.
