In a Beijing Hutong in 1979, the morning light passed through the gray tile eaves and shone on the smiling face of 17-year-old high school student Lin Xiangyang. No one knew that this young man who always loved to help his neighbors with repairs and was known as the "Pistachio" of the courtyard was accidentally bound to the pure knowledge-based AI "Qiming" from the future.
When a massive cross-era knowledge base unfolded in his mind, and when sophisticated analysis and deduction capabilities became a secret weapon, Lin Xiangyang did not indulge in fantasy. He used "coal-saving tips" to warm up the neighborhood fireworks, used "technical tips" to help his father, a fitter at the rolling mill, solve equipment problems, used forward-looking vision to point out the direction of transformation for the confused factory, and even took the lead in protecting the courtyard that carries memories during the demolition storm.
In the era of food stamps, radios, and 28-bar bicycles, he used sunny humor to resolve the trivialities of life, and used the power of knowledge to light up the hope around him. From helping classmates overcome academic difficulties, to keeping jobs for factory workers, to opening the door to top universities with excellent results, Lin Xiangyang always remembers: Qiming is the star that lights the way forward, and the land under his feet, the family around him and the pulse of the times are the roots that support him moving forward.
This is a story about knowledge, growth and the times - when a young man's brain meets the spring breeze of reform and opening up, he can develop the power to change the future in ordinary days.
