In 1982, Qin Fu, who was ridiculed as a "little workhorse", was saving money to buy cream for her seriously ill mother, but unexpectedly showed off her skills in a machinery factory. Lin Wenbo, a cold-faced technician, originally thought she was squeamish and unmotivated, but during repeated confrontations, he was moved by her hard work of designing on a sewing machine and running the entire factory. From floral skirts to overalls, the two worked together to overcome difficulties and embrace reforms, letting gears and needles weave the glory of the times, and turning prejudice into heartbeats.
