Precision: My Rebirth in the Workshop at the Age of 35

At the age of thirty-five, the world Lin Jiang was familiar with suddenly became silent. The day before, he was still in the glass-walled conference room, weaving the future with bright words such as "empowerment", "ecology" and "subversion". The next day, he stood in the roaring workshop and couldn't even read the scale of the vernier caliper. From software sales to workshop apprenticeship, he needed to relearn everything: Learn the language of steel - listen to the roar of cutting to see if it's too fast or too dull, and see if the color of the iron filings is normal or overheated. Learn the dignity of your hands - let the fingers that once hit the keyboard find the trembling sense of proportion in the precision of 0.01 Mm. Learn real weight - there are no "virtual solutions" here, just the unfalsifiable blue fire of the mill as it cuts through the steel. This is a retrograde movement. When everyone flocks to the lighter, faster, and more virtual world, he turns around and walks toward the heaviest, slowest, and most real depths. From "green key man" to programmer, from craftsman to entrepreneur, every step is marked by the smell of oil, iron filings and coolant. But it is also the most solid redemption. In an era when everything can be copied, pasted, and undone, he chose to enter a world where mistakes will be permanently engraved on steel. Here, precision is morality and craftsmanship is life.
