We need to write an article without title (the user says "直接输出正文，不要标题"). Title is given, but we should not output the title. So just the body. Must be 6-8 paragraphs, each 150-250 characters? Actually they said 150-250字, meaning Chinese characters count, not words. So each paragraph 150-250 Chinese characters. Need total >=1500 characters, <1050 not allowed. So need about 6-8 paragraphs each ~200 characters => total ~1200-1600 characters. Must be >=1500 characters, so maybe 8 paragraphs of ~200 each = 1600 characters. Must be natural, conversational, no AI phrases.
We must avoid banned words. Also avoid AI style. Use specific details, case studies, personal tone.
We need to answer "学校地图标注有什么". Provide key info about campus map annotation: types of markings, how to read, significance, usage tips, hidden gems, etc.
Paragraph constraints: 150-250 Chinese characters each. Let's aim for about 180-200 characters each.
We need 6-8 paragraphs. Let's produce 7 paragraphs, each around 200 characters. Ensure total >1500 characters. Let's count approximate characters.
Paragraph 1: ~200 chars.
Total ~1400, need >1500. So perhaps 8 paragraphs of ~200 each => 1600. Let's do 8 paragraphs.
Paragraph length target 180-200 Chinese characters. Let's craft.
We need to ensure no banned words: avoid "、可以...等". Also avoid "". Use natural flow.
Write in conversational tone.
Let's draft paragraph 1: "昨天在宿舍楼里，看到几位同学盯着手机上的校园地图翻来翻去，我忍不住好奇，到底这些标记到底在说啥。" That's about 40 characters. Need 150-250 characters. So expand.
Paragraph 1: "昨天在宿舍楼里，看到几位同学盯着手机上的校园地图翻来翻去，我忍不住好奇，到底这些标记到底在说啥。原来不只是简单的路线示意，里面藏着不少实用信息，今天就带大家拆解一下，帮你少走弯路，找到心仪的打卡点。" Let's count characters: We'll approximate. Probably around 120. Need 150-250. Let's expand more.
Paragraph 1 target 180-200 characters. Let's write:
"昨天在宿舍楼里，看到几位同学盯着手机上的校园地图翻来翻去，我忍不住好奇，到底这些标记到底在说啥。原来不只是简单的路线示意，里面藏着不少实用信息，甚至能帮你快速定位图书馆、咖啡厅甚至实验室的位置。今天就带大家拆解一下，看看哪些标记最值得关注，怎么利用它们避开绕路，直接冲进自己想去的地方。" Let's count roughly: maybe 180 characters. Good.
Paragraph 2: talk about types of markings: building icons, facilities, green spaces, etc. Need 150-250 characters.
Paragraph 2 draft: "校园地图上的标记分得 quite 细，除了教学楼、实验楼这些硬核建筑，还会标出图书馆的层数、食堂的用餐时间段，甚至停车场的空位情况。比如，有些图书馆会用不同颜色的小标签标明「热门座位区」或「安静阅读区」，直接在图上一眼看出哪里最适合刷论文，省去找座位的折腾。" Approx length maybe 180.
Paragraph 3: talk about navigation tips: using landmarks, using QR codes, etc.
Paragraph 3 draft: "在拿到一张新图后，第一步往往是找几个易识别的地标，比如校门口的大花塔、中心广场的喷泉或者学院的标志性建筑。这些点往往被标成红色图标，点开后会弹出历史信息或是校园网的链接，直接点进去就能看到开放时间、活动预告，甚至导航到最近的公交站。这样一来，走迷路的尴尬就不太会发生了。" Approx 200.
Paragraph 4: talk about hidden gems and unofficial markings: student-run maps, social media tags.
Paragraph 4 draft: "除了官方发布的图，学生们自己在社交平台上也会分享自己的「打卡路线图」，上面会标出一些官方地图上没有的小众景点，比如老槐树下的咖啡摊、图书馆的屋顶花园，甚至是实验室的咖啡机位置。这些信息往往只有在朋友圈或是校园论坛里才能看到，但对想要体验校园文化的同学来说，是宝藏。" Approx 200.
Paragraph 5: talk about how to interpret symbols: colors, icons, legends.
Paragraph 5 draft: "地图上的颜色和图标需要配合图例才能看懂，官方地图通常会在角落标注「颜色说明」：红色代表教学楼，蓝色是行政楼，绿色则是绿化带或是运动场。有时候，不同的线型也暗藏玄机，虚线可能是夜间照明路线，点划线则是禁止进入区域。把这些细节弄清楚后，你就能在夜晚的校园里也能自如前行，避免被错误的指示带进禁区。" Approx 200.
Paragraph 6: talk about practical usage: planning routes, avoiding crowds, time management.
Paragraph 6 draft: "很多同学利用地图来做课表排课时，会把上课的教室标记出来，顺便把午休、自习的地点也标上，形成一条完整的行程线。这样一来，早起赶早课的同学能提前预判走路的时间，甚至在上课前抢到附近的咖啡店坐等。还有人利用地图的「步行时间」标注，直接把相邻的课堂排在同一条线上，省下十几分钟的奔波，感觉一天都轻松不少。" Approx 200.
Paragraph 7: talk about updates and digital maps.
Paragraph 7 draft: "校园地图并非一成不变，尤其是新建的实验楼、学生公寓陆续启用后，官方会不定期更新数字版。最新的版本往往会同步推送到学校的官方APP里，支持搜索功能，输入「咖啡厅」就能直接定位到最近的几家店。而且，有些APP还能根据你的位置实时推送附近的空教室或是空余的自习位，这种实时反馈让学习节奏更加高效，也让那些怕迷路的同学安心不少。" Approx 200.
Paragraph 8: conclusion, echo title.
Paragraph 8 draft: "所以，校园地图标注不只是纸上的线条，更像是一张连接学习、生活和社交的导航图。只要掌握几个关键点，你就能在校园里像拥有自己的专属坐标系，轻松找到想去的地方，甚至发现一些只有细心才会注意到的小惊喜。下次时间一到，不妨打开手机地图，跟着那些不容错过的标记，去探索属于你的校园秘密吧。" Approx 200.
Now total characters likely >1500. Need to ensure each paragraph 150-250 characters. Let's count roughly each paragraph length.
Paragraph 1: maybe ~190 characters. Good.
Total ~1520 characters.
We must not use banned words. I need to scan for any banned words: "、可以...等". I haven't used them. I used ""? Not used. "可以...等"? Not used. Also avoid "". Not used. Avoid "让我们". Not used. Avoid "。" That's
