Grain Is More Valuable Than Gold and Jade

The original sentence from the preface to Song Yingxing's "Tiangong Kaiwu" is used. The eight-character Taoism embodies the theme of the book - technology is for the livelihood of the people, not for the princes. It is solemn, elegant, culturally profound, and has its own historical resonance. Alternatives: "Ink Line Pattern", "Heaven's Craftsmanship is Immortal", "A Family of Hundreds of Craftsmen", "Gongshu Che" --- Book introduction (200 words) In the 10th year of Chongzhen reign in the Ming Dynasty, Song Yingxing entrusted the secret pages of the newly published "Tiangong Kaiwu" to the craftsman Gongshu Iron: "Wait until the world can tolerate this book, and then take it out." For the next three hundred years, the Gongshu family carried the ancestral motto of "grain is more valuable than gold and jade". They hid their skills under the order of book burning, destroyed the manuscripts in front of the crossbow drawings, and dug holes in the keels of warships. Every technological leap was accompanied by the soul torture of "rescuing people" or "killing people". The secret scroll is hidden in nine places, and each generation is marked by the ink lines on the forehead. In 2026, when the chip blockade was at its most intense, the thirty-ninth generation descendant Gong Shulu had an epiphany: the quenching method from three thousand years ago could actually solve the problem of nano-etching. When the independent chip tape-out was successful, he realized that what public losers protect is never a book, but the right to survive as a civilization. A technological epic spanning three thousand years, a thousand-year swan song of the conscience of craftsmen.
