The Fire Stays On

A blacksmith kept an ironworks for sixty years. A knife with the word "Yue" engraved on it has been hanging on the wall for nearly a thousand years. Twelve volumes of "Military Industry Minutes" were written from Jingkang to the end of the Song Dynasty, and were passed from one person's hands to countless others. There is no overnight success or failure, only the inheritance of one fire after another. The green smoke of this ironworks has never stopped.
