We need to output the article content only, no title. Must be 1500+ characters (not words; Chinese characters count). Must be 150-250 characters per paragraph, 6-8 paragraphs. Must start with opening that echoes title, then middle, then ending that echoes title.
We need to ensure total characters >=1500. 6 paragraphs * 150 = 900, but need 1500, so need longer paragraphs, maybe 8 paragraphs of ~200 characters each = 1600 characters. Must be 150-250 characters each. Let's aim for 8 paragraphs of ~200-210 characters each. That will be about 1680 characters.
We must not use any AI-sounding words. Must be natural, conversational.
We need to avoid banned words: 开头禁用：、; 过渡禁用：、; 结尾禁用：让我们...、。今天就手把手教你怎么把普通的示意图变成专业的标注图，整个过程其实很简单。" Need about 200 chars.
Paragraph 2: Explain preparation: Choose software, prepare base map. Use simple language.
Paragraph 3: Step of adding points, naming.
Paragraph 4: Step of drawing lines, adding text.
Paragraph 5: Step of finalizing, export.
Paragraph 6: Tips and common pitfalls.
Paragraph 7: Real-world example.
Paragraph 8: Closing echo title.
We need each paragraph 150-250 Chinese characters.
Let's draft each paragraph and then count characters.
Paragraph 1 draft: "你有没有想过，地图上那些小图标其实背后藏着不少技巧？今天就手把手教你怎么把普通的示意图变成专业的标注图，整个过程其实很简单，完全不需要专业软件，跟着我一步步操作就行。"
Now count characters (including punctuation?). Chinese characters count includes punctuation? Usually count characters not words. Let's count roughly:
"你有没有想过，地图上那些小图标其实背后藏着不少技巧？今天就手把手教你怎么把普通的示意图变成专业的标注图，整个过程其实很简单，完全不需要专业软件，跟着我一步步操作就行。"

That's about 78 characters, too short. Need 150-250 characters. Need to expand.
We can add more detail: "你有没有想过，地图上那些小图标其实背后藏着不少技巧？今天就手把手教你怎么把普通的示意图变成专业的标注图，整个过程其实很简单，完全不需要专业软件，跟着我一步步操作就行，哪怕是第一次接触也能快速上手。" Let's count roughly.
Add more: "甚至不用熟悉复杂的功能，只要打开地图文件，选好标记工具，点几下就能完成。" Let's rewrite to get around 200 characters.
Paragraph 1 target length ~200 characters.
I'll craft a paragraph of about 200 characters.
Paragraph 1: "你有没有想过，地图上那些小图标其实背后藏着不少技巧？今天就手把手教你怎么把普通的示意图变成专业的标注图，整个过程其实很简单，完全不需要专业软件，跟着我一步步操作就行，哪怕是第一次接触也能快速上手，整个流程只有几分钟。" Let's count characters roughly.

That's about 97 characters, still short. Need 150-250. Need more content.
Add more sentences: "我们会先准备好基础的底图，然后通过简单的标记工具把关键位置标出来，再把文字、符号补充进去。整个项目不需要太多时间，却能让你的地图看起来更直观、更专业。" Let's combine.
Now write full paragraph maybe 200 characters.
Paragraph 1 final: "你有没有想过，地图上那些小图标其实背后藏着不少技巧？今天就手把手教你怎么把普通的示意图变成专业的标注图，整个过程其实很简单，完全不需要专业软件，跟着我一步步操作就行，哪怕是第一次接触也能快速上手，整个流程只有几分钟。我们会先准备好基础的底图，然后通过简单的标记工具把关键位置标出来，再把文字、符号补充进去，整个项目不需要太多时间，却能让你的地图看起来更直观、更专业。" Let's count roughly.
