We need to produce a 1500+ word article (must be at least 1500, cannot be less than 1050). Must be 6-8 paragraphs, each 150-250 words. Title is fixed, but they say "直接输出正文，不要标题". So we should output only the body, no title. Need 6-8 paragraphs, each 150-250 words. So total words must be at least 1500, but also cannot be less than 1050. So we need to produce around 1500-1800 words, each paragraph 150-250 words.

We need 6-8 paragraphs. Let's aim for 7 paragraphs, each about 210-220 words, that'll give about 1540 words. Ensure each paragraph length is between 150 and 250 words.

We must keep natural, conversational tone, avoid AI-sounding phrases. No transition words like "" etc. Use short sentences, active voice.

We must not include the title. Only the body.

We need to ensure each paragraph is 150-250 Chinese characters? Actually they said "字数要求：必须写满1500字，不能少于1050字！". That's characters? In Chinese, they refer to "字数" meaning characters count. But they also said each paragraph 150-250字, which likely means characters. So each paragraph must be 150-250 Chinese characters, not words. So we need to count characters. Let's aim for about 200 Chinese characters per paragraph. 7 paragraphs * 200 = 1400 characters, which is less than 1500 required. Actually they require total characters >=1500, and each paragraph 150-250 characters. So we need at least 1500 characters total. If we have 7 paragraphs each 220 characters, total ~1540 characters, meeting requirement. Also each paragraph must be 150-250 characters, so 220 is fine.

Thus we need to produce 7 paragraphs, each about 220 Chinese characters. Must not include title. Must not use banned words. Must not use transition words like "、". Must avoid those. Use natural flow.

We must avoid AI-sounding phrases: "", "". Also avoid "非常重要", "十分关键", etc.

We need to write about "地图通常按什么绘制的". Provide details: scale, coordinate systems, projection, data sources, purpose, audience, simplification, conventions, cultural context, etc. Use concrete examples.

We need to keep each paragraph 150-250 characters. Let's craft paragraphs of roughly 220 characters.

We need to count characters. Let's draft paragraph 1 about 220 characters.

Paragraph 1: "地图绘制背后的秘密，究竟遵循何种规则？其实，每张地图都不是凭空想象，而是有明确的框架在里面。想要画出一张合格的地图，得决定要展示的范围和目的。是要标出全国的交通线路，还是只关注某座城市的街道布局？不同的目标会直接决定要收集的数据种类和细节深度。于是，我们会先列出需要呈现的核心要素，比如行政边界、主要河流、交通枢纽以及关键地标。把这些要素列出来后，接下来就是对它们的位置进行标记。这时候，坐标系统就派上用场了。"

Count characters? Let's count roughly. Might be around 200 characters. Need to ensure each paragraph 150-250 characters. Let's approximate.

Better to write paragraphs of about 220 Chinese characters. Let's manually count roughly.

I'll draft each paragraph, then count characters roughly.

Paragraph 1: "地图绘制背后的秘密，究竟遵循何种规则？其实，每张地图都不是凭空想象，而是有明确的框架在里面。想要画出一张合格的地图，得决定要展示的范围和目的。是要标出全国的交通线路，还是只关注某座城市的街道布局？不同的目标会直接决定要收集的数据种类和细节深度。于是，我们会先列出需要呈现的核心要素，比如行政边界、主要河流、交通枢纽以及关键地标。把这些要素列出来后，接下来就是对它们的位置进行标记。这时候，坐标系统就派上用场了。"

Now count characters: Let's count manually (including punctuation?). Usually Chinese characters count includes punctuation? Usually characters count includes punctuation? But we can approximate. Let's count characters ignoring punctuation maybe. Let's count characters:

"地图绘制背后的秘密，究竟遵循何种规则？" -> characters: 地(1)图2? Actually each Chinese character counts as 1. Let's count:

， (punctuation not counted? Usually punctuation not counted as character? But in Chinese character count, punctuation maybe counts as a character? Usually they count characters including punctuation? Not sure. But roughly we can approximate total characters including punctuation is okay. We'll aim for ~220 characters including punctuation.

Better to write paragraphs of about 200-250 characters. Let's approximate length.

I'll write each paragraph with about 230 characters. Then 7 paragraphs => ~1610 characters, which meets >=1500.

Now craft paragraphs:

Paragraph 1 (intro) about 230 characters.

Paragraph 2 about 230 characters.

Paragraph 3 about 230 characters.

Paragraph 4 about 230 characters.

Paragraph 5 about 230 characters.

Paragraph 6 about 230 characters.

Paragraph 7 conclusion about 230 characters.

Make sure no banned transition words.

Avoid "、". Use natural flow.

Also avoid "", "". Use plain language.

Also avoid "非常重要", "十分关键", etc.

Also avoid "让我们...", "。其实，每张地图都不是凭空想象，而是有明确的框架在里面。想要画出一张合格的地图，得决定要展示的范围和目的。是要标出全国的交通线路，还是只关注某座城市的街道布局？不同的目标会直接决定要收集的数据种类和细节深度。于是，我们会先列出需要呈现的核心要素，比如行政边界、主要河流、交通枢纽以及关键地标。把这些要素列出来后，接下来就是对它们的位置进行标记。这时候，坐标系统就派上用场了。"

Now count characters: Let's count quickly (including punctuation). I'll count characters manually (including Chinese characters, punctuation maybe counted). Let's count characters:

"地图绘制背后的秘密，究竟遵循何种规则？" -> characters: 地1 图2 绘3 制4 背5 后6 的7 秘8 密9 ，10 究11 竟12 遵13 循14 何15 种16 规17 则18 ؟19 (question mark) maybe counts as char. So around 19.

But we need total ~230 characters across whole paragraph. Let's count whole paragraph characters.

I'll copy paragraph and count roughly.

地图绘制背后的秘密，究竟遵循何种规则？其实，每张地图都不是凭空想象，而是有明确的框架在里面。想要画出一张合格的地图，得决定要展示的范围和目的。是要标出全国的交通线路，还是只关注某座城市的街道布局？不同的目标会直接决定要收集的数据种类和细节深度。于是，我们会先列出需要呈现的核心要素，比如行政边界、主要河流、交通枢纽以及关键地标。把这些要素列出来后，接下来就是对它们的位置进行标记。这时候，坐标系统就派上用场了。

Now count characters (including punctuation) roughly. Let's count words per sentence.

I'll count characters manually approximate: I'll write each character count.

I'll use a rough estimate: each Chinese character ~1, punctuation also counts maybe 1. Let's count.

I'll copy the paragraph and count using mental grouping.

地图绘制背后的秘密，究竟遵循何种规则？ (19?) Let's count precisely:

地1 图2 绘3 制4 背5 后6 的7 秘8 密9 ，10 究11 竟12 遵13 循14 何15 种16 规17 则18 ？19

其实，每张地图都不是凭空想象，而是有明确的框架在里面。 Count:

But we need to ensure each paragraph is between 15
