We need to write an article with title given, but user says "直接输出正文，不要标题". So we output only the body, no title. Must have 6-8 natural paragraphs, each 150-250 Chinese characters. Must be at least 1500 characters total, cannot be less than 1050 characters. So we need roughly 150-250 per paragraph * 6-8 paragraphs => total 900-2000 characters. Must be at least 1500 characters total. So we need about 7 paragraphs each ~215 characters -> total ~1500. Ensure each paragraph length 150-250 characters (including Chinese characters count). We'll produce 7 paragraphs approx 215 characters each. Must not use AI writing prompts. Must avoid listed words. Must not use "、". Also avoid "" etc. Must not use those prohibited words. Must use natural, conversational style.
We need to talk about "优化数据库的八种方法". Must mention eight methods. Provide details. Avoid using the banned transition words. Must use short sentences, active voice, concrete details.
We need opening paragraph that echoes title: "告别卡顿，八招让数据库性能翻倍飙升". Should start with something like "别再让数据库卡顿拖累业务了". Then mention eight招.
We need middle paragraphs each discuss some methods, maybe 2-3 methods per paragraph. Need to list eight methods across paragraphs. Provide details.
We need concluding paragraph that echoes title and gives viewpoint.
Make sure each paragraph is 150-250 Chinese characters. Let's aim for about 200 characters each.
We must count characters roughly. Chinese characters count includes punctuation? Usually count characters, punctuation not counted? But safe to keep within range.
Let's craft 7 paragraphs of ~200 characters each.
Paragraph 1: ~200 characters.
Paragraph 2: ~200 characters.
Paragraph 3: ~200 characters.
Paragraph 4: ~200 characters.
Paragraph 5: ~200 characters.
Paragraph 6: ~200 characters.
Paragraph 7: ~200 characters.
Total ~1400 characters, need at least 1500. So maybe 8 paragraphs of ~190 characters each => total ~1520. Let's do 8 paragraphs.
Paragraph count 8, each 150-250 characters.
We'll write 8 paragraphs.
Paragraph 1: Introduce problem and title.
Paragraph 2: Method 1: 索引优化.
Paragraph 3: Method 2: 适当拆分大表.
Paragraph 4: Method 3: 读写分离.
Paragraph 5: Method 4: 连接查询优化.
Paragraph 6: Method 5: 批量写入/事务.
Paragraph 7: Method 6: 缓存策略.
Paragraph 8: Method 7&8: 监控与调优 + conclusion.
But we need eight methods; we can combine two in last paragraph.
Make sure each paragraph 150-250 characters.
Let's craft each paragraph.
Paragraph 1 (~200 characters):
"别再让数据库卡顿拖累业务了，今天给大家拆解一套实操的八招，帮助你把性能直接翻倍。我们不谈空洞理论，只聊能立刻落地的技巧，无论是电商、社交还是金融系统，都能看到明显提升。"
Count characters: Let's approximate. Chinese characters count: "别再让数据库卡顿拖累业务了，今天给大家拆解一套实操的八招，帮助你把性能直接翻倍。我们不谈空洞理论，只聊能立刻落地的技巧，无论是电商、社交还是金融系统，都能看到明显提升。" Let's count roughly: 1)别(1)再2)让3)数4)据5)库6)卡7)顿8)拖9)累10)业11)务12)了13、14? Actually punctuation not counted? But approximate length maybe ~70 characters? Wait need 150-250 characters. My draft is too short. Need to expand.
We need each paragraph 150-250 characters, not words. So we need about 150 Chinese characters per paragraph. My paragraph is too short. Need to write longer.
Thus need to produce paragraphs of ~200 characters. Let's aim for about 200 characters each.
We must count roughly. Let's craft longer sentences.
We'll write each paragraph about 200 characters.
Let's draft paragraph 1 of about 200 characters:
"别再让数据库卡顿拖累业务了，今天给大家拆解一套实操的八招，帮助你把性能直接翻倍。我们不谈空洞理论，只聊能立刻落地的技巧，无论是电商、社交还是金融系统，都能看到明显提升。"
Count characters: Let's count manually.
"别"1 "再"2 "让"3 "数"4 "据"5 "库"6 "卡"7 "顿"8 "拖"9 "累"10 "业"11 "务"12 "了"13 "，" punctuation maybe not count but still char. We'll count Chinese characters ignoring punctuation? Usually characters include punctuation? But approximate length is low. Need ~200 characters, so we need longer.
Let's write longer paragraph with more details.
Paragraph 1: "别再让数据库卡顿拖累业务了，今天给大家拆解一套实操的八招，帮助你把性能直接翻倍。我们不谈空洞理论，只聊能立刻落地的技巧，无论是电商、社交还是金融系统，都能看到明显提升。" That's still short.
We need to add more sentences to reach 150-250 characters. Let's expand:
"别再让数据库卡顿拖累业务了，今天给大家拆解一套实操的八招，帮助你把性能直接翻倍。我们不谈空洞理论，只聊能立刻落地的技巧，无论是电商、社交还是金融系统，都能看到明显提升。想象一下，原来需要等待数秒的查询，现在只要毫秒级响应，用户体验自然会跃升。"
Now count characters roughly: Let's count Chinese characters (including punctuation maybe not). I'll approximate: "别再让数据库卡顿拖累业务了，今天给大家拆解一套实操的八招，帮助你把性能直接翻倍。我们不谈空洞理论，只聊能立刻落地的技巧，无论是电商、社交还是金融系统，都能看到明显提升。想象一下，原来需要等待数秒的查询，现在只要毫秒级响应，用户体验自然会跃升。"

That's about 115 characters? Actually we counted many but maybe less. Need 150-250. So we need to add more content.
Let's craft a longer paragraph with more details, maybe 200 characters.
I'll write a paragraph of about 200 characters, then count roughly.
"别再让数据库卡顿拖累业务了，今天给大家拆解一套实操的八招，帮助你把性能直接翻倍。我们不谈空洞理论，只聊能立刻落地的技巧，无论是电商、社交还是金融系统，都能看到明显提升。想象一下，原来需要等待数秒的查询，现在只要毫秒级响应，用户体验自然会跃升。更重要的是，提升后系统负载下降，运维成本也能随之降低，这正是我们追求的终极收益。"
Now count characters roughly: Let's count manually (including punctuation maybe). I'll count characters ignoring punctuation but count Chinese characters.
