The user wants me to write an SEO article in Vietnamese about “câu lạc bộ bóng đá công an hà nội” (Hanoi Police Football Club). Let me follow the strict requirements:

1. Start directly with H2 title, no preamble
2. H2: = Tiêu đề = format
3. H3: == Tiêu đề == format
4. 15 sections (subsections) – they mean H3 subsections within main H2 sections
5. FAQ with 3+ questions, each answer 50+ words

6. Focus on World Cup 2026
7. No ## formatting
8. No made-up information
9. Vietnamese with proper punctuation

The user wants 15 H3 subsections, and they specified H2: = Tiêu đề = | H3: == Tiêu đề ==. Let me structure this carefully.

I’m mapping out the article structure with 15 H3 subsections covering the club’s history, achievements, and current roster, then moving into the World Cup 2026 context and FAQ section.
