Soldering Copper Gutter Under Day Night Sky in Hangzhou

Bright tropical light floods the riverside landing in Hangzhou, illuminating a tinsmith focused on soldering a seam along a gleaming copper rainwater gutter. The worker wears a heavy apron, crouched low against the metal structure. A sharp, horizontal line divides the sky above: the left side glows with late afternoon sun and low-hanging clouds, while the right side plunges instantly into a deep, star-filled night. The copper surface reflects both the golden afternoon glow and the cool, distant starlight simultaneously. Sparks from the soldering iron float upward, catching the dual illumination. The metal seam glows orange where the tool touches, against the cool blue of the night sky reflected in the gutter's curve. one drop of molten solder hangs suspended on the edge, mirroring the transition between the two worlds.
