- Positioned sharply on the upper-left section is the clear corporate text hierarchy: "XÂY DỰNG NHÂN HIỆU BÁN HÀNG TRIỆU ĐÔ" using a premium mix of massive crisp white block characters and heavy bold 3D extruded polished golden metallic font with clean mirror reflections.
- Below the title banner on the left: A vertical list text column cleanly aligned displaying bullet points for lesson details. The top-left corner holds a fine area for a company corporate logo brand. Ultra-sharp text contours, perfect advertising grid layout, 8k resolution, wide aspect ratio 2:1.
