We need to produce an article, no title, 6-8 paragraphs, each 150-250 characters? Wait they said "每段150-250字". Means characters? Actually Chinese characters count as words? They want each paragraph 150-250 Chinese characters. And total must be 1500+ characters, at least 1050. They said must be 1500字以上, cannot be less than 1050. So we need at least 1500 Chinese characters total. 6-8 paragraphs, each 150-250 characters => total between 900-2000. But they also require 1500+ characters, so we need around 7 paragraphs each ~215 characters => total about 1505. That meets. Must be natural, no AI words, no banned phrases. Must not use the prohibited transition words (、... etc). Also avoid opening with those. Must not use summary words at end. Must not use "、". Must not use "让我们...", "。我们今天就聊聊怎么把数据库无缝迁移，避免踩坑。" Let's count characters: "搬数据库就像 搬家一样，别担心，只要按部就班，轻松完成。我们今天就聊聊怎么把数据库无缝迁移，避免踩坑。" Count: 搬(1) 数据库(3) 就(1) 如(1) 样(1) (space?) Chinese char count includes punctuation? Usually count characters including punctuation? Likely count characters ignoring punctuation? Hard to know. We'll approximate. Let's just aim for 180-200 characters per paragraph.
Better to write longer paragraphs.
We need total 1500+ characters. Let's craft 7 paragraphs each about 220 characters.
I'll write paragraphs with about 220 Chinese characters.
Paragraph 1: "把数据库搬到新环境，听起来像是件大事，其实只要把握几个关键点，就能像搬家一样顺畅。我们先不说理论，直接上手怎么把数据迁移过去，别让old数据卡住新系统。" Let's count characters: "把"(1) "数据库"(3) "搬"(1) "到"(1) "新"(1) "环境"(2) "，"(punct) maybe count but ignore. This is messy. Better to write longer.
I'll write paragraphs of roughly 230 characters.
Paragraph 1: "数据库迁移不是什么神秘的技术，它和我们搬家、换电话号码其实差不多。只要把原有的数据整理好，再搬到新服务器上，整个过程就能顺利进行。接下来，我就把具体的操作步骤拆解出来，让你能一步步跟着做，而不是干等指导。" Let's count roughly: I'll count characters manually.
I'll write a paragraph and then count.
"数据库迁移不是什么神秘的技术，它和我们搬家、换电话号码其实差不多。只要把原有的数据整理好，再搬到新服务器上，整个过程就能顺利进行。接下来，我就把具体的操作步骤拆解出来，让你能一步步跟着做，而不是干等指导。"
Now count characters (including punctuation?). Let's count Chinese characters ignoring punctuation and spaces.
I'll count each Chinese character and maybe numbers.
Paragraph 1 characters count:
数(1) 据(2) 库(3) 迁(4) 移(5) 不(6) 是(7) 什(8) 么(9) 神(10) 秘(11) 的(12) 技(13) 术(14) ，(punct) we ignore. It and so on.
Better to just approximate length. Probably around 100 characters? Actually it's longer. Let's approximate: The paragraph likely ~180 characters. Let's trust that each paragraph will be around 200-250 characters.
We need total 1500+. So 7 paragraphs of ~220 each => 1540 characters. Good.
Now need to ensure each paragraph 150-250 characters. We'll aim for ~220.
Now write paragraphs.
Paragraph 1: "数据库迁移不是什么神秘的技术，它和我们搬家、换电话号码其实差不多。只要把原有的数据整理好，再搬到新服务器上，整个过程就能顺利进行。接下来，我就把具体的操作步骤拆解出来，让你能一步步跟着做，而不是干等指导。" Let's assume length ~180? Might be less. Let's expand.
Add more sentences: "把表、视图、索引这些细节都列出来，像打包箱子一样分类整理，这样搬走时不会遗漏。" Let's incorporate.
Let's rewrite paragraph 1 with more content to reach ~220 characters.
"数据库迁移不是什么神秘的技术，它和我们搬家、换电话号码其实差不多。先把所有表、视图、索引这些细节列出来，像打包箱子一样分类整理，这样搬走时不会遗漏。把原有的数据整理好，再搬到新服务器上，整个过程就能顺利进行。接下来，我就把具体的操作步骤拆解出来，让你能一步步跟着做，而不是干等指导。"
Now count approximate characters: Let's count quickly.
"数据库迁移不是什么神秘的技术，它和我们搬家、换电话号码其实差不多。" => about 30 characters.
"先把所有表、视图、索引这些细节列出来，像打包箱子一样分类整理，这样搬走时不会遗漏。" => about 35.
"把原有的数据整理好，再搬到新服务器上，整个过程就能顺利进行。" => about 25.
"接下来，我就把具体的操作步骤拆解出来，让你能一步步跟着做，而不是干等指导。" => about 30.
Total maybe 120? Actually maybe more. Let's trust it's around 150-180. Need 150-250 each, okay maybe 180 is fine. But we need 6-8 paragraphs each 150-250. So okay.
But we need total 1500+. If each ~180, 8 paragraphs => 1440, not enough. So we need longer paragraphs, maybe 220-250 each. Let's aim for about 230 characters each. So we need to expand.
Let's write longer paragraphs with more details.
Paragraph 1: Let's write about 230 characters.
Paragraph 1 draft (expanded):
"数据库迁移看起来像是大工程，其实和搬家、换手机号没什么不同。先把所有表、视图、索引这些细节列出来，像打包箱子一样分类整理，这样搬走时不会遗漏。把原有的数据整理好，再搬到新服务器上，整个过程就能顺利进行。接下来，我把具体的操作步骤拆解出来，让你能一步步跟着做，而不是干等指导。"
Now count characters: Let's count roughly.
"数据库迁移看起来像是大工程，其实和搬家、换手机号没什么不同。" => about 28 characters.
"先把所有表、视图、索引这些细节列出来，像打包箱子一样分类整理，这样搬走时不会遗漏。" => about 34.
"把原有的数据整理好，再搬到新服务器上，整个过程就能顺利进行。" => about 24.
"接下来，我把具体的操作步骤拆解出来，让你能一步步跟着做，而不是干等指导。" => about 28.
That's ~114 characters, still low. Actually Chinese characters count includes each Chinese character, not words. The sentences are longer. Let's count more precisely.
I'll count each Chinese character (including punctuation maybe). Let's write the paragraph exactly and count.
