In the roaring factory, amidst the flickering arc light, Cheng Lanjun holds the welding torch with a steady hand like a rock. This experienced welder, who has been working on the front line of bridge assembly for thirteen years, interprets the craftsman spirit of "perseverance, focus, and excellence" with his calloused hands, writing an extraordinary story of persistence on an ordinary post.

Double guardianship of safety and quality"The lifting must be done with a traction rope, and people should stand far away. These rules cannot be compromised in the slightest." As an experienced worker who once served as a safety supervisor, Cheng Lanjun's emphasis on safety is deeply ingrained in his bones. This reverence for safety has long been transformed into an extreme pursuit of quality. "Craftsmanship? In the end, it's about doing a good job." Cheng Lanjun's interpretation is straightforward and powerful. Even if the schedule is tight and the task is heavy, he never compromises on quality. "Working overtime until midnight is common, but reworking is more troublesome than working overtime. Quality is the real saving." This attitude of "not settling for anything less than perfection" is the core essence of craftsmanship.

The Relay of Skill and Morality"I've mentored countless apprentices over the years, and while teaching skills is important, passing on the rules is even more crucial." Cheng Lanjun is not only a "veteran" in terms of technology but also an inheritor of the craftsman spirit. He personally corrects the grip of guns, repeatedly demonstrates precise measurement techniques using scrapped components, and explains the dangers of illegal operations through his own experiences. His teachings have instilled a habit of excellence in many apprentices. Nowadays, many of his apprentices have become technical backbones in various positions, continuing to pass on this craftsmanship.

Craftsmanship Shines Through Ordinary Life When asked about the essence of craftsmanship, Cheng Lanjun didn't quote any classical works. Instead, he pointed to the newly welded bridge frame and said, "Look at this weld bead. It's smooth and even without any air holes, and the assembly is seamless. This is the spirit of craftsmanship." In his view, craftsmanship means repeatedly doing simple things well and achieving excellence in complex tasks.
Cheng Lan's thirteen-year perseverance proves that the spirit of craftsmanship is never an unattainable concept. It is hidden in every precise operation, evident in every safety guard, and integrated into every apprenticeship. Just like countless craftsmen who dedicate themselves silently, in him, we see the professional pursuit of "doing one's job well, loving one's job, and becoming an expert in one's job", and we also understand the profound connotation of the spirit of craftsmanship, which is "to see the true essence in the details".
