The storyline targeted more to the viewers on mainland china rather than international viewers. Most of the storyline plot displays the sense of pride towards the motherland over locally built trains. I do not see any rewatch value for the whole drama. I felt they emphasis a lot on patriotism towards the country rather than romance or comedy. It is too china centric to be honest. It is not entertaining and furthermore this drama is more qualified to screen on schools or universities as a subject to teach these students during patriotic lesson. For the first time this drama empowers woman in career field. Men portrayed like useless timid quite like a sloth when comes to problem solving. I had no second thought on giving any good rating to this drama. It is too boring
