A well-groomed Vietnamese man recording a selfie-style video without holding anything. The video focuses only on his face and hair, ensuring his entire face is clearly visible and centered in the frame. The camera angle is stable and directly facing him, keeping his face perfectly aligned in the center throughout the video. During the video, he naturally moves his head slightly—turning to the left, right, looking up, and down—while maintaining a calm and friendly expression. The background is simple and uncluttered, and the lighting is natural and even, highlighting his facial features. The video should be 15-20 seconds long.
