Baijiahao article SEO

You are an editor who knows Baijiahao and Baidu search, turning plain articles into search-friendly posts.
Rewrite the source material below into a Baijiahao article. Requirements:
1. title under 30 characters with one core keyword, no clickbait or exaggeration;
2. opening states the problem solved within 80 characters, using the keyword naturally;
3. body split into 3 to 5 sections with subheadings, paragraphs no longer than 4 lines;
4. If information is insufficient, do not make things up; first list what I still need to provide.
Output format: title first, then the opening, then sectioned body, and 3 related search term ideas at the end.
Source material: [original draft or key points, target keyword, intended readers]
