Create a 15-second vertical 9:16 photorealistic Chinese baozi breakfast commercial in 4K at 24fps. Use the same four Chinese family members throughout: a young woman around 24 years old with shoulder-length dark hair, a cream blouse, and a pastel cardigan; a mother around 46 years old with a neat low bun and beige blouse; a father around 48 years old with short black hair and a light-gray shirt; and a young man around 22 years old wearing a light-blue overshirt over a white shirt. Preserve their exact faces, hairstyles, ages, clothing, and body proportions in every scene. Their acting must feel warm, restrained, believable, and naturally affectionate. The featured product is freshly steamed Chinese pork-and-scallion baozi with fluffy white dough, neat pleated tops, fully cooked juicy filling, and gentle realistic steam. From 0.0–2.0 seconds, show a wide establishing shot of the family seated around a bright round wooden table. A bamboo steamer filled with baozi sits at the center as morning sunlight enters through large windows. An off-screen Mandarin female narrator says: 「清晨，从一笼热气开始。」 Only the narrator speaks. All visible mouths remain still. From 2.0–4.0 seconds, cut to a medium close-up of the young woman presenting the bamboo steamer toward the camera with a friendly smile. She says clearly in Mandarin: 「刚出笼的包子，快尝尝！」 The narrator remains completely silent. Use precise Mandarin lip synchronization. From 4.0–6.0 seconds, show an extreme macro shot of a hand opening the bamboo-steamer lid as warm steam reveals several soft white baozi. The narrator says: 「皮薄松软，热气腾腾。」 No visible person speaks. From 6.0–8.0 seconds, show the family sharing baozi with wooden chopsticks. The father serves one to the mother and says: 「大家一起吃吧。」 Only the father speaks. From 8.0–10.0 seconds, show the young man taking one natural bite, swallowing fully, then smiling and saying: 「太香了！」 He must not speak with food visible inside his mouth. The narrator remains silent during both dialogue scenes. From 10.0–11.5 seconds, show an extreme macro close-up of a baozi opened in half, revealing fluffy dough and moist fully cooked pork-and-scallion filling. The narrator says: 「鲜香肉馅，汁水饱满。」 From 11.5–13.0 seconds, show the family happily enjoying breakfast together. The young woman says: 「吃饱了，今天有精神！」 Only she speaks; the others respond silently with natural smiles. From 13.0–14.0 seconds, show wooden chopsticks gently lifting one baozi from the steaming basket. No dialogue or narration.
