A Chinese little girl, about 8-10 years old, with long legs, standing on a dilapidated staircase. She has golden hair in a bun, adorned with pearls and pink small flowers, a sweet and obedient smile on her face, with bright blue eyes. She is wearing a magnificent mermaid princess dress, with a necklace of three strands of pearls from the Night Song, eye shadow and eyeliner applied, a tight corset on top, decorated with sparkling beads and crystals, giving off a prismatic sheen; the skirt is made of multiple layers of white sheer fabric and tassels, also adorned with bead chains and gems. Her hands are placed on both sides, her body slightly leaning forward, facing the camera, one leg lifted, wearing white socks on her feet. The background is gray walls and dark stairs. The lighting is soft, illuminating the girl's face and the details of her outfit, creating a dreamy and elegant atmosphere. The composition is centered on the girl, with a slightly upward perspective, highlighting the fineness of the costume and the girl's cuteness.
