Back to 1983: From Exam Failure to Electronics Guru

A programmer at a major tech company drops dead and wakes up in 1983 as an unemployed young man in a county town. His father has retired due to illness, his mother runs a street stall, and he can't even secure a factory job. His mind is full of code, algorithms, and memories of the next forty years. But in this era, there isn't even a computer. What others see as junk, he sees as treasure. Radios others can't fix, he repairs in no time. Starting out by finding bargains at the scrap yard, he trades government bonds and collects rare monkey stamps, then makes his way to Zhongguancun and Shenzhen. Years later, people finally understand: that poor kid who started out repairing appliances went to Shenzhen and, bit by bit, repaired the entire 1980s into his own era.
