We need to produce a 1500+ words article, with 6-8 paragraphs, each 150-250 words. Must be about "cnrds数据库实操指南，从入门到熟练使用". Title is given, but we must not output title, just the body. Must be natural, conversational, no AI clichés. Must not use banned words. Must have 6-8 paragraphs, each 150-250 words. Must be at least 1500 words total, cannot be less than 1050. So aim for around 1700-1800 words, with 7 paragraphs of about 230-250 words each => 7*230=1610; we can do 7 paragraphs each ~210-230 words => total ~1500-1600. Let's do 7 paragraphs of ~230 words each => 1610 words. Ensure each paragraph 150-250 words. Must not use banned transition words like "", etc. Also avoid intro filler like "". Must not use banned words in the list. Must avoid "非常重要", "十分关键". Must not use "让我们...", "。其实它不把重点放在理论堆砌，而是把手把手的步骤拆解成几个小块。你打开第一章，就会发现作者直接把数据库的基本概念用生活化的语言说清楚，比如什么是表、什么是字段、什么是索引。不会出现那种高深的学术词汇，只有你能听懂的说法。比如把索引比作图书馆的目录，让你一眼就明白它的作用。整个开篇就把目标摆出来：不是让你记住所有命令，而是让你能够在真实项目里动手操作。于是，读者在读完第一章后，就能在本地装好cnrds，跑通第一个简单的表。这样一来，后面的内容就好像在搭积木，一块一块往上叠。整个段落大约两百多字，直接把话题拉进实操的状态，让人感觉像朋友聊天一样自然。"
Now count words. Let's approximate: Chinese words count? The requirement is 1500 Chinese characters? Actually they said 1500字, meaning characters? Usually Chinese "字" means characters, but they said 1500字以上, meaning at least 1500 characters. So we need at least 1500 Chinese characters, not words. So we need to produce at least 1500 Chinese characters. That's easier: we can produce around 200-250 characters per paragraph. So we need to ensure total characters >=1500. So we need to produce enough characters.
Our paragraphs should be 150-250 Chinese characters each. That's easier. So we need to produce about 200 characters per paragraph. Let's aim for ~200 characters each.
Thus we need to produce about 200 characters per paragraph. Let's count characters manually? Approximate.
Paragraph 1 we wrote about 200 characters? Let's count roughly: "先说说cnrds数据库实操指南，从入门到熟练使用，这本书的核心思路是啥。其实它不把重点放在理论堆砌，而是把手把手的步骤拆解成几个小块。你打开第一章，就会发现作者直接把数据库的基本概念用生活化的语言说清楚，比如什么是表、什么是字段、什么是索引。不会出现那种高深的学术词汇，只有你能听懂的说法。比如把索引比作图书馆的目录，让你一眼就明白它的作用。整个开篇就把目标摆出来：不是让你记住所有命令，而是让你能够在真实项目里动手操作。于是，读者在读完第一章后，就能在本地装好cnrds，跑通第一个简单的表。这样一来，后面的内容就好像在搭积木，一块一块往上叠。整个段落大约两百多字，直接把话题拉进实操的状态，让人感觉像朋友聊天一样自然。"
That is maybe ~300 characters? Let's approximate: Chinese characters count includes punctuation? Probably count characters including punctuation. Hard to count precisely, but it's likely >200. Might be okay.
But we need 6-8 paragraphs each 150-250 characters. So we need to ensure each paragraph length is within that range. Let's aim for ~180-200 characters each. That would give total ~1300-1600 characters, meeting requirement.
Now we need to produce 7 paragraphs each about 180-200 characters. Let's craft each paragraph carefully to be around that length.
We must avoid banned words. Also avoid using "". Use "先". Avoid "". Use "随后". Avoid "". Use "继续". Avoid "". Use "最终". Avoid "总结". Avoid "让我们". Avoid "希望". Avoid "相信". Avoid "期待". Avoid "非常重要". Avoid "十分关键". Avoid "不可或缺". Avoid "". Also avoid "". Already
