Jiang Xin plays Jin Cangliang, a female elite who has been transferred from a railway female soldier, from the chief of the security section to the driver of the electric locomotive. Tong Dawei plays Chang Hanqing, an electric locomotive engineer who has returned from studying abroad and has spent his life fighting for the dream of locomotives.

Jin Cangliang and Chang Hanqing, one is a "rich man" from a capital background, the other is an ordinary railway female soldier, from the initial mutual inability to see each other, and then to the heart of the heart after experiencing tempering together, the combination of the two people is not only the love of children, but also the concerted development of the railway and locomotive undertakings. The two people have struggled hard for their careers and dreams all their lives, which is admirable!
When the two people got married, the eldest son, Chang Junbo, was extremely pampered. Chang Hanqing and his sister Chang Hankun themselves are both returning from overseas and have advanced and enlightened thoughts, while Jin Cangliang is even more kind and upright, under the care of the three of them, Chang Junbo has shown cleverness and cleverness since he was a child, and he is likable. In that era, the background of the capitalists was actually very discriminated against, especially the power engine factory and Feng Shigao, who had been holding on to the Chang family and not letting up.
Suspecting that the Chang family was hiding gold bars, Feng Shigao ordered the Chang family to surround the Chang mansion and forbid anyone to enter and exit, especially to check the packages. Chang Hankun originally wanted to take the gold bars out through the reason of the family maid's return to his hometown, but Feng Shigao was really too strictly supervised and could only give up.
Feng Shigao is about to carpet search, in order to survive the crisis in the family, Chang Junbo took the initiative to ask for help, to take out the gold bars disguised as forged. Chang Hankun's heart was both touched and unbearable, afraid that he would be tired of Chang Junbo because of his own affairs.
Chang Junbo firmly said that there was no problem, Feng Shigao still wanted to embarrass Chang Junbo, but this little clever ghost was really too clever, he knew Feng Shigao's intentions and guessed, and said in a child's characteristic naïve tone, "Stupid, Uncle Feng, don't you just want to find gold bars, my mother's comrades in arms of the engineering battalion..." Chang Junbo's reminder made Feng Shigao suddenly realize, and then let Chang Junbo go.
Feng Shigao's attitude towards Chang Junbo is actually because Chang Junbo is Jin Cangliang's hard-won son, and the problem that Jin Cangliang could not have children at the beginning was that Feng Shigao specifically asked his mother to solve it. For Chang Junbo, Feng Shigao also has a kind of kindness and care for the elders, so he will easily believe the words in Chang Junbo's mouth.
Seeing such a witty and calm And unhurried Chang Junbo, Chang Hankun's tight heart finally let go, and there seemed to be tears in his eyes, and he said: "It is worthy of the Chang family's species"! Chang Junbo knew how dangerous and important the gold bars he carried were. Placed next to the railroad track that even Chang Hankun did not know and could not imagine, he successfully guarded the gold bars of the Chang family.
Growing up in such a family, in fact, from a young age, you can see that Chang Junbo's vision and pattern are by no means "mortal products". After growing up, Chang Junbo and Chang Hankun settled abroad to learn various advanced knowledge and technology. Finally, when he returned to China, his son inherited his father's business and took over the power locomotive business of Chang Hanqing and Jin Cangliang, constantly improving and researching and developing, and finally having an independent and advanced level of independent research and development and design.
