When she woke up, Su Lan, who had just received the title of senior engineer, transformed into a glorious female technician at the Red Star Machinery Factory in the 1980s. Good news: I have an iron rice bowl, including food and accommodation, and a huge monthly salary of thirty yuan! Bad news: The maintenance workshop where she works is at the bottom of the contempt chain of the whole factory. The equipment is outdated and the people are unmotivated. It is about to be beaten to death on the beach by the wave of reform. To make matters worse, she was the only woman in the entire workshop, so she was nicknamed "Little Vase". The old masters held cigarettes in their mouths and looked at her sideways: "Xiao Su, there is a lot of oil here, so don't stain your braji (dress)." Competitors were angry: "Women, just do the logistics, what can you do in front-line production?" Even her blind date advised her: "For girls, it's hard to work in the factory, so why not get married early and I will support you." Su Lan wiped the oil on her hands and smiled. Feed her? Sorry, she just wants to support this workshop that is about to close down and the group of hard-spoken and soft-hearted old masters inside. Later - the "foreign equipment" imported from abroad was not adapted to the local environment, and the whole factory was helpless. Su Lan took a piece of hand-drawn paper and spent three days and three nights to get it started again. The factory was engaged in technological innovation, and everyone was scratching their heads. The transformation plan submitted by Su Lan directly quadrupled the production efficiency, which shocked everyone. The blind date who once advised her to get married was so regretful that her intestines turned blue when she saw the headline "Technical pacesetter Su Lan" in the newspaper. And the thorn-headed master who always loved to quarrel with her and had the worst temper was showing off to everyone everywhere: "Did you see it? My apprentice! I taught you this!"
