I Just Graduated from College and You Want Me to Be the Factory Director?

Time travels back to 1990, my father suffered a stroke, and the family's only dilapidated factory is about to close down. My relatives all persuaded me to sell the factory and work. Mr. Wang next door was waiting to see my jokes. Even my fiancée came to break off the engagement! No one knows that I, Li Zheng, come from thirty years later! Facing everyone's ridicule, Li Zheng silently took out the drawings that transcended the times. While others are still tinkering, my first generation CNC machine tool has quietly rolled off the production line! When others imitate my products, my industrial base machine has begun to earn foreign exchange through export! From a screw, to a car engine, to a large aircraft, to a photolithography machine... A few years later, the person who mocked me had already gone bankrupt, and I was already standing at the top of the global industry, watching the storm with a smile! 3.
