We need to produce 1500+ Chinese words, divided into 6-8 paragraphs, each 150-250 characters (words? It says "字数要求：必须写满1500字，不能少于1050字！ 结构要求：分成6-8个自然段 每段150-250字". So each paragraph should be 150-250 characters? Or words? In Chinese, "字" usually means characters, but they say "字数要求：必须写满1500字，不能少于1050字！" So total characters must be at least 1500 characters, at most? Probably at least 1500 characters. Each paragraph 150-250 characters. 6-8 paragraphs. So total characters = between 6150=900 and 8250=2000. But we need at least 1500 characters, so we need to produce maybe 7 paragraphs of about 215 characters each, total ~1505 characters. Must be at least 1500 characters. Must be exactly the content, no title, just body. Must start with opening that references the title "手绘班级大学地图，收藏四年青春坐标". Must end with concluding that also references the title. Must not use AI detection triggers like "" etc. Must avoid formal phrases. Must write like a seasoned media person, natural, conversational, with specifics, anecdotes, analysis, etc. Must avoid banned words list. Must not use "、..." etc. Must not use "让我们...", "。" That's fine.

We need to avoid "。" That's fine.

We need to avoid "非常重要、十分关键、不可或缺、值得关注". So avoid those adjectives.

We need to avoid "、". So avoid those.

We need to avoid "". So avoid that.

We need to avoid "". So avoid that phrase.

We need to avoid "在...的背景下". So avoid that phrase.

We need to avoid "的背景". Possibly safe.

We need to avoid "的背景". Might be okay but safer not to use "背景". Use "在校园里" is fine.

Now produce 7 paragraphs each 150-250 characters. Let's count approximate characters.

Paragraph length: Chinese characters count includes punctuation? Usually count characters including punctuation? Probably count characters excluding punctuation? But we can approximate. We'll write paragraphs of about 200 characters each.

Paragraph 1: Opening referencing title. Something like: "那天我们把一张纸摊在宿舍地板上，几支彩笔在灯光下划出城市的轮廓，标记了图书馆的灯塔、食堂的蒸汽、实验楼的玻璃窗。那一刻，手绘班级大学地图不再是一张纸，而是把四年的足迹压进方寸之间的坐标。" Need about 200 characters.

Paragraph 2: Talk about process, details, how they made it, the choices, the memories attached.

Paragraph 3: Talk about significance, how it reflects class identity, shared experiences.

Paragraph 4: Talk about specific scenes, like the night market, the library, the sports field, etc.

Paragraph 5: Talk about the evolution, adding stickers, postcards, etc.

Paragraph 6: Talk about how it survived, passed down, became a ritual.

Paragraph 7: Conclusion referencing title, reflecting on memory, future.

We need to ensure each paragraph is 150-250 characters. Let's approximate.

We'll write paragraphs with about 200 characters each.

Now let's count characters roughly.

"那天我们把一张纸摊在宿舍地板上，几支彩笔在灯光下划出城市的轮廓，标记了图书馆的灯塔、食堂的蒸汽、实验楼的玻璃窗。那一刻，手绘班级大学地图不再是一张纸，而是把四年的足迹压进方寸之间的坐标。"

Count characters: Let's count manually (including punctuation?). We'll just approximate length. It seems maybe around 130 characters? Let's count precisely:

"那天我们把一张纸摊在宿舍地板上，几支彩笔在灯光下划出城市的轮廓，标记了图书馆的灯塔、食堂的蒸汽、实验楼的玻璃窗。那一刻，手绘班级大学地图不再是一张纸，而是把四年的足迹压进方寸之间的坐标。"

Let's count characters (including punctuation but not spaces). I'll count:

So about 93 characters? Actually we counted 93 characters (including punctuation). That's too short; we need 150-250 characters per paragraph. So we need longer paragraphs.

We need each paragraph 150-250 characters. So we need to expand to about 200 characters each.

Let's craft longer paragraphs.

Paragraph 1: Need ~200 characters.

"那天我们把一张厚纸摊在宿舍的木地板上，几支彩色圆珠笔在昏黄的灯光里划出城市的轮廓，笔尖轻点标记了图书馆的灯塔、食堂的蒸汽、实验楼的玻璃窗，甚至走廊里偶尔传来的笑声都成了坐标。纸面慢慢铺开，像一张微缩的地图，把四年的校园脉络压进方寸之间，仿佛把时间卷进了这张手绘的大学图。"

Now count characters roughly.
