We need to produce article 1500+ characters, must be 6-8 paragraphs, each 150-250 words. So total 6-8 paragraphs * ~175 avg = ~1050-1400 words. Must be 1500+ characters, but requirement says must write at least 1500 characters? Actually says "字数要求：必须写满1500字，不能少于1050字！" Chinese characters count? They say must write 1500 characters (字) and cannot be less than 1050 characters. So we need at least 1500 Chinese characters. Paragraph length 150-250 characters? It says each paragraph 150-250字 (characters). So each paragraph 150-250 Chinese characters. 6-8 paragraphs => total 900-2000 characters. Need at least 1500 characters, so we need maybe 7 paragraphs of ~215 characters each => 1505 characters. Must be 6-8 paragraphs, each 150-250 characters. We'll aim for 7 paragraphs, each ~215 characters => total ~1505 characters, meeting 1500+ requirement. Must not include title. Must be natural, no AI phrases. Avoid listed banned words. Must not use "、". Also avoid intro filler. Must start with opening that echoes title. Must end with concluding that echoes title.
We need to talk about "数据迁移的四种方法". Provide practical guide. Use specific examples, real-world scenarios. Use short sentences, active voice. Avoid passive.
We need to produce only the article body, no title.
We need to ensure each paragraph 150-250 characters. Let's craft 7 paragraphs of about 215 Chinese characters each.
We must count characters. Let's draft paragraph 1 ~215 characters.
Paragraph1: "搬砖的朋友常被问，怎么把数据从旧平台搬到新系统？今天把四种主流迁移方式拆解给你看清楚。每种方法都有适用场景，关键在怎么选对工具。" Let's count characters. Chinese characters count includes punctuation? Usually count characters not spaces. Let's count: 搬砖的朋友常被问，怎么把数据从旧平台搬到新系统？今天把四种主流迁移方式拆解给你看清楚。每种方法都有适用场景，关键在怎么选对工具。 Let's count manually:
搬(1)砖2的3朋友4常5被6问7，8怎么9把10数据11从12旧13平台14搬15到16新17系统？18今天19把20四21种22主流23迁移24方式25拆解26给27你28看29清30。每31种32方法33都34有35适用36场景，37关键38在39怎么40选41对42工具43。 That's 43 characters, too short. Need 150-250 characters per paragraph. So need much longer.
We need each paragraph 150-250 characters, not words. So each paragraph must be fairly long.
Let's aim for about 200 characters each. We'll write paragraphs of ~200 Chinese characters.
We need 7 paragraphs.
Paragraph1: Opening, echo title.
Paragraph2: Method1 description.
Paragraph3: Method2 description.
Paragraph4: Method3 description.
Paragraph5: Method4 description.
Paragraph6: Comparison and tips.
Paragraph7: Conclusion echoing title.
We must ensure each paragraph 150-250 characters.
Let's craft paragraph1 ~200 characters.
"搬砖的同学们总想快速把数据从旧系统搬到新平台，却怕踩坑耽误进度。其实数据迁移并不神秘，关键在于挑对方法。今天把四种高效搬迁方式一次讲透，帮你少走弯路。" Let's count characters.
搬1砖2的3同4学5们6总7想8快9速10把11数12据13从14旧15系16统17搬18到19新20平21台22，却23怕24踩25坑26耽27误28进29度30。其实31数32据33迁34移35并36不37神38秘39，关40键41在42挑43对44方45法46。今天47把48四49种50高51效52搬53迁54方55式56 一57次58讲59透60，帮61你62少63走64弯65路66。 That's 66 characters, still short. Need 150+ characters. Must be longer.
Let's expand with more detail.
"搬砖的同学们总想快速把数据从旧系统搬到新平台，却怕踩坑耽误进度。其实数据迁移并不神秘，关键在于挑对方法。不同业务场景需要不同搬运工具，盲目使用会浪费时间。今天把四种高效搬迁方式一次讲透，帮你少走弯路，直接上手。" Count characters.
Let's count roughly: I'll count manually.
搬1砖2的3同4学5们6总7想8快9速10把11数12据13从14旧15系16统17搬18到19新20平21台22，却23怕24踩25坑26耽27误28进29度30。31其实32数33据34迁35移36并37不38神39秘40，关41键42在43于44挑45对46方47法48。49不50同51业52务53场54景55需56要57不58同59搬60运61工62具63，盲64目65使66用67会68浪69费70时71间72。73今天74把75四76种77高78效79搬80迁81方82式83一84次85讲86透87，帮88你89少90走91弯92路93，直94接95上96手97。 That's 97 characters. Still need ~150. Need to add more sentences.
Add more: "不管你是数据仓库搬迁，还是日志同步，都有对应的最佳实践。下面我们逐一拆解四种主流方案，看看它们的优势和适用限制。" Add characters.
Add: 不管1你2是3数4据5仓6库7搬8迁9，还是10日11志12同13步14，都15有16对17应18的19最20佳21实22践23。24下面25我26们27逐28一29拆30解31四32种33主34流35方36案37，看38看39它40们41的42优43势44和45适46用47限48制49。 That's about 49 characters. So total now ~97+49=146 characters. Need 150-250, so add a bit more: maybe "我们先从最常用的全量复制说起。" That's about 13 characters? Let's count: 我1们2先3从4最5常6用7的8全9量10复11制12说13起14。 That's 14 characters. So total ~160. Good.
Add after previous sentence: "我们先从最常用的全量复制说起。" So final paragraph1 will be about 160 characters.
Let's rewrite paragraph1 fully with proper punctuation and count again roughly.
"搬砖的同学们总想快速把数据从旧系统搬到新平台，却怕踩坑耽误进度。其实数据迁移并不神秘，关键在于挑对方法。不同业务场景需要不同搬运工具，盲目使用会浪费时间。今天把四种高效搬迁方式一次讲透，帮你少走弯路，直接上手。我们先从最常用的全量复制说起。"
Now count characters precisely (including punctuation as characters). Let's count:
