Su Yu'an and Zhou Jingchuan work in seamless harmony from morning to dusk across the sample archive, the presentation room, and the photo preparation area. Together they handle six sample boxes and three sets of geometric recognition cards—from check-out sequencing and group calibration to mapping out the presentation layout and fine-tuning camera framing parameters. Through dozens of meticulous steps, they repeatedly adjust every detail, verifying each movement path and prop position one by one, completing the entire sample showcase preparation with a rigorous, steady rhythm that captures the refined texture and dedicated craftsmanship of workplace collaboration.
