In the winter of 1962, Lin Feng traveled through time and became a technician in "The Courtyard".
In an era when supplies were scarce, he relied on the system mall and future knowledge in his mind to start as a third-level fitter in a steel rolling mill.
Transform old Soviet equipment, develop a magnetic scale system, and break through the technical blockade.
Faced with the ups and downs of human relationships in the courtyard, the overt and covert struggles in the factory, and the numerous restrictions of the times.
He quietly lit up the spark of China's industry——
CNC machine tools, precision sensors, adaptive algorithms... A number of "black technologies" have taken root and sprouted in this special era.
From courtyard houses to factories across the country, from technicians to "industrial leaders."
This is a breakthrough road for Chinese technical people.
