The user wants a Chinese article of at least 1500 characters (words?) they said "字数要求：必须写满1500字，不能少于1050字！" So we need at least 1500 Chinese characters, not words. They want 6-8 paragraphs, each 150-250 characters. Must start with title already given, but they say "直接输出正文，不要标题". So we just output the body, no title. Must be natural, conversational, no AI phrasing. Must be about "有免费标注的地图吗". Title is "想找免费标注地图，看这篇就够了，良心推荐". They want 6-8 paragraphs, each 150-250 characters. Let's aim for 7 paragraphs of ~200 characters each => total ~1400 characters, need at least 1500 characters, so maybe 8 paragraphs of ~200 each => 1600 characters. Ensure each paragraph length ~150-250 characters. We'll craft paragraphs.

Paragraph1: around 180-200 characters, opening, echo title.

Paragraph2: talk about why free annotated maps matter, personal anecdote.

Paragraph3: talk about specific resources: OpenStreetMap, Google My Maps (free), etc.

Paragraph4: talk about steps to use them, screenshots? Not needed.

Paragraph5: talk about limitations, need for accuracy, crowdsourcing.

Paragraph6: talk about other tools like QGIS, MAPS.ME, etc.

Paragraph7: talk about practical uses, travel planning.

Paragraph8: concluding, call to action.

Make sure each paragraph 150-250 characters. Count characters roughly.

We need to count Chinese characters. Let's draft paragraphs about 200 characters each.

Paragraph1: "想找免费标注地图，看这篇就够了，良心推荐" is the title, but we cannot output title. We need to start article with something that echoes it. So first paragraph could be: "最近有朋友问我，怎么在网上找免费的标注地图？其实并不难，今天就给大家分享几款靠谱的工具，亲测好用，省时又省钱。" That's about 70 characters? Let's count: "最近有朋友问我，怎么在网上找免费的标注地图？其实并不难，今天就给大家分享几款靠谱的工具，亲测好用，省时又省钱。" Count characters: 最近(2)有(1)朋友(2)问(1)我(1)，怎么(2)在(1)网(1)上(1)找(1)免(1)费(1)的(1)标(1)注(1)地(1)图(1)？(1)其实(2)并(1)不(1)难(1)，今天(2)就(1)给(1)大(1)家(1)分(1)享(1)几(1)款(1)靠(1)谱(1)的(1)工具(2)，亲(1)测(1)好(1)用(1)，省(1)时(1)又(1)省(1)钱(1)。 That's maybe 70-80 characters. Need 150-250 characters per paragraph. So we need longer.

We can make each paragraph about 180-200 characters. Let's craft paragraphs of roughly 180 characters.

I'll draft paragraphs and then count.

Paragraph1 (180 chars):

"最近有朋友问我，怎么在网上找免费的标注地图？其实并不难，今天就给大家分享几款靠谱的工具，亲测好用，省时又省钱。不管是出门游玩还是商务出差，随手一搜就能拿到带有路名、景点、行政区划等信息的地图，完全不用花钱。下面就一步步带你看看怎么操作，轻松搞定所有标注需求。"

Now count characters: Let's count manually.

最近(2)有(1)朋友(2)问(1)我(1)，怎么(2)在(1)网(1)上(1)找(1)免(1)费(1)的(1)标(1)注(1)地(1)图(1)？(1)其实(2)并(1)不(1)难(1)，今天(2)就(1)给(1)大(1)家(1)分(1)享(1)几(1)款(1)靠(1)谱(1)的(1)工具(2)，亲(1)测(1)好(1)用(1)，省(1)时(1)又(1)省(1)钱(1)。不管(2)是(1)出(1)门(1)游(1)玩(1)还是(2)公(1)司(1)商务(2)出(1)差(1)，随(1)手(1)一(1)搜(1)就(1)能(1)拿(1)到(1)带(1)有(1)路(1)名(1)、景(1)点(1)、行政(3)区(1)划(1)等(1)信息(2)的(1)地(1)图，完全(2)不(1)用(1)花(1)钱(1)。下(1)面(1)就(1)一(1)步(1)带(1)你(1)看(1)得(1)到(1)怎么(2)操(1)作(1)，轻(1)松(1)搞(1)定(1)所有(2)标(1)注(1)需(1)求(1)。 Total characters: Let's sum: 2+1+1+1+2+1+1+1+2+1+1+2+1+1+1 = let's approximate around 150? Might be less. Need 150-250 characters. This paragraph maybe ~130. So need longer.

We can expand with more details.

I'll rewrite longer paragraph ~190 characters.

Paragraph1: "最近有朋友问我，怎么在网上找免费的标注地图？其实并不难，今天就给大家分享几款靠谱的工具，亲测好用，省时又省钱。不管是出门游玩还是商务出差，随手一搜就能拿到带有路名、景点、行政区划等详细信息的地图，完全不用花钱。下面我就一步步演示使用过程，帮助你轻松搞定所有标注需求，省去找资源的麻烦。"

Now count roughly: Let's approximate length. It seems longer, maybe ~180-200 characters. We'll trust it's within range.

Paragraph2: talk about why free annotated maps are useful.

Paragraph2: "为什么大家会特别关注免费标注地图呢？因为在日常工作和生活中，我们经常需要快速定位某个地点、查看周边设施，或者把自己的行程标记出来方便分享。比如计划一次自驾游，直接在地图上标记出加油站、餐馆和景点，能让行程更有条理；团队协作时，把共同的任务地点标注出来，也能提升沟通效率。免费的地图资源正好满足这些需求，并且不需要额外付费。" Count ~200 characters.

Paragraph3: talk about specific tools: OpenStreetMap, Google My Maps, etc.

Paragraph3: "最常用的免费标注地图其实有几个渠道，其中OpenStreetMap（OSM）是个开源的全球地图平台，几乎可以在上面找到任何地方的详细街道和建筑信息。配合OSM的编辑器iD，你可以直接在网页上添加路名、标记地标，甚至绘制自定义图层。另外，Google My Maps也是个不错的选择，登录后可以把自己的标记、路线和文字批注直接上传，支持导出为KML或分享链接，操作起来非常直观。" Count ~210 characters.

Paragraph4: steps to use these tools.

Paragraph4: "下面给大家演示一下在Google My Maps上标注的具体步骤：第一步打开Google账号登录后进入My Maps页面，点击‘创建新地图’；第二步在地图上搜索目标地点，右键选择‘添加标记’，输入名称并拖动到想要的位置；第三步可以在标记属性里添加描述、图片或链接，方便后续查看；点击保存并分享链接给朋友或同事即可。整个过程几分钟就能完成，完全免费，而且支持多语言，使用门槛低。" Count ~250 characters maybe a bit high but okay.

Paragraph5: discuss limitations and crowdsourcing.

Paragraph5: "不过，免费地图也有它的小缺点，比如信息更新速度可能滞后，某些新建筑或临时路线在地图上还未标注。为了解决这个问题，很多平台鼓励用户参与编辑，比如OSM的贡献者社区，你可以提交修改或新增数据，系统会在审核通过后自动更新。这样一来，地图的准确性会逐步提升，而且每次编辑都不需要
