A young adult female subject is depicted in a mirror selfie within an indoor environment featuring dark gray tiled walls and a reddish-brown door, consistent with a public or commercial building in China, specifically the Huangdao District. The subject has dark hair parted in the middle and displays smudges of dirt or soot on her forehead and left cheek, with a reddish mark near the right corner of her mouth. She wears a stained work uniform consisting of a gray long-sleeved shirt under a fluorescent yellow-green, gray, and dark gray high-visibility vest. The vest shows inverted text "OЭM-OЭN" (likely NEO-ECO) and two logos, along with two chest pockets, one being a clear ID holder. Extensive reddish-brown splatters, consistent with blood, are present on the vest and the sleeves of the underlying shirt. The subject holds a silver/gray smartphone with a multi-lens camera in her left hand, using it to capture the reflection. The smartphone case features an image of a dinosaur's head, possibly a Tyrannosaurus Rex, with an open mouth. The background reflection also reveals a white rectangular wall plate with two switches and a partially visible white sign with black Chinese characters reading "请勿..." (Please do not...).
