Quiet Rhythm Sleep is a dynamic process?moving in rhythm from sleep onset to light sleep, and ultimately into deep sleep. The visual identity of Jingyun follows this inherent rhythm: core elements such as the logo, stripes, and flags are all developed around the idea of "rhythm," forming a cohesive system with a sense of breath. As a key visual language, the flag serves both to structure product categorization and evolution, and to express the brand's core value of "ultra-softness" through gentle, flowing forms.
