We need to write an article, no title, but around 1500+ characters? The user says "必须写满1500字，不能少于1050字！" Means must reach 1500 words? Or characters? They say "字数要求：必须写满1500字，不能少于1050字！" So must be at least 1500 characters? Actually "字数" usually means characters/words? They say "1500字" which in Chinese usually means characters, but they also say "不能少于1050字". So need at least 1500 Chinese characters. They also say structure: 6-8 paragraphs, each 150-250 characters. So total characters: 6150=900 up to 8250=2000. To meet at least 1500 characters, we need maybe 7 paragraphs of ~215 characters each = 1505 characters. So we need to produce 6-8 paragraphs, each 150-250 characters, total at least 1500 characters. Let's aim for 7 paragraphs of ~220 characters each = 1540 characters. Must be natural, human-like, no AI words. Must not start with certain phrases. Must not use transition words like "、". Must avoid "", etc. Must not use "明确、具体、清晰、详细、展开...层层递进". Must not use "需要注意的是、需要强调的是、值得注意的是、可以看到、可以认为、可以得出、可以认为是、需要注意到、需要考虑到、需要关注到". Must not use "综合来看、从...的角度来看、...方面、...层面". Must not use "在...的...中". Must not use typical AI connectors.
We need to write about "如何找数据集". Provide concrete tips, examples. 6-8 paragraphs, each 150-250 Chinese characters. Each paragraph 150-250 characters, not words. Chinese characters count includes punctuation? Usually characters include punctuation. We'll approximate length.
We must not include title. Just output the article.
We must avoid using disallowed words. Let's craft 7 paragraphs each about 220 characters.
Paragraph 1: about why need reliable data, mention title.
Paragraph 2: talk about define goal, understand what you need.
Paragraph 3: talk about public repositories, like Kaggle, UCI.
Paragraph 4: talk about domain-specific sources, government open data.
Paragraph 5: talk about building your own dataset, web scraping, APIs.
Paragraph 6: talk about evaluate data quality, check sources, documentation.
Paragraph 7: talk about next steps, maintain, share, wrap up.
Need to ensure each paragraph length 150-250 Chinese characters. Let's count approximate characters.
I'll draft paragraph 1 ~210 characters.
Paragraph 1: "数据几乎成了每个项目的燃料。无论是做机器学习模型、进行市场分析，还是写一篇研究报告，找到一份靠谱的数据集都是关键第一步。本文把常见的获取渠道、挑选技巧以及注意事项全部摆出来，帮助小白从零开始，轻松搞定数据收集。" Let's count characters: I'll count roughly. Each Chinese character counts as one. Let's count: "数据几乎成了每个项目的燃料。" That's about 18? Let's do systematic: I'll approximate total length later.
But need 150-250 characters each. Let's aim for about 200 characters each.
I'll write paragraphs and then count roughly.
"数据几乎成了每个项目的燃料。无论是做机器学习模型、进行市场分析，还是写一篇研究报告，找到一份靠谱的数据集都是关键第一步。本文把常见的获取渠道、挑选技巧以及注意事项全部摆出来，帮助小白从零开始，轻松搞定数据收集。"
Now count characters: Let's count manually.
"在"1 "今"2 "天"3 "的"4 "信"5 "息"6 "爆"7 "炸"8 "时"9 "代"10 "，"11 "数"12 "据"13 "几"14 "乎"15 "成"16 "了"17 "每"18 "个"19 "项"20 "目"21 "的"22 "燃"23 "料"24 "。"25 "无"26 "论"27 "是"28 "做"29 "机"30 "器"31 "学"32 "习"33 "模"34 "型"35 "、 " (punctuation maybe not count?) but we count characters including punctuation? Usually Chinese characters count includes punctuation? Might not matter. Continue: "进"36 "行"37 "市"38 "场"39 "分"40 "析"41 "，"42 "还"43 "要"44 "写"45 "一"46 "篇"47 "研"48 "究"49 "报"50 "告"51 "，"52 "找"53 "到"54 "一"55 "份"56 "靠"57 "谱"58 "的"59 "数"60 "据"61 "集"62 "都"63 "是"64 "关"65 "键"66 "第"67 "一"68 "步"69 "。"70 "本"71 "文"72 "把"73 "常"74 "见"75 "的"76 "获"77 "取"78 "渠"79 "道"80 "、 " (punct) "挑"81 "选"82 "技"83 "巧"84 "以"85 "及"86 "注"87 "意"88 "事"89 "项"90 "全部"91 "摆"92 "出"93 "来"94 "，"95 "帮"96 "助"97 "小"98 "白"99 "从"100 "零"101 "开"102 "始"103 "，"104 "轻"105 "松"106 "搞"107 "定"108 "数"109 "据"110 "收"111 "集"112 "。"113
So about 113 characters. Need 150-250. Need to add more.
Add more sentences: "而且，掌握正确的渠道还能节省不少时间和金钱，避免踩坑。下面先聊聊怎么明确自己的需求。" Let's count additional characters.
"而且，掌握正确的渠道还能节省不少时间和金钱，避免踩坑。" Count: "而"1 "且"2 "，"3 "掌"4 "握"5 "正"6 "确"7 "的"8 "渠"9 "道"10 "还"11 "能"12 "节"13 "省"14 "不"15 "少"16 "时"17 "间"18 "和"19 "金"20 "钱"21 "，"22 "避"23 "免"24 "踩"25 "坑"26 "。"27
So add 27 characters, total now ~140. Need about 150-250, so we are close to 140, need a bit more maybe 10-20 more characters.
Add "先想清楚要的变量、时间范围和准确度要求。" Count: "先"1 "想"2 "清"3 "楚"4 "要"5 "的"6 "变"7 "量"8 "、"9 "时"10 "间"11 "范"12 "围"13 "和"14 "准"15 "确"16 "度"17 "要"18 "求"19 "。"20
Now total ~160 characters. Good.
Paragraph 1 final approx 160 characters. That meets 150-250.
Paragraph 2: talk about define goal and understand data needed.
Draft: "先给自己画个数据图谱，明确要解决的问题和需要的指标。比如，想预测房价，就得关注面积、楼层、朝向这些核心字段；做用户画像，则要收集年龄、消费习惯、地区分布等属性。把这些需求写在纸上或备忘录里，能帮助你在后面的搜索中快速过滤掉不相关的资源，避免信息过载。" Let's count characters.
Count roughly: "先"1 "给"2 "自"3 "己"4 "画"5 "个"6 "数"7 "据"8 "图"9 "谱"10 "，"11 "明"12 "确"13 "要"14 "解"15 "决"16 "的"17 "问"18 "题"19 "和"20 "需"21 "要"22 "的"23 "指"24 "标"25 "。"26 "例"27 "如"28 "，"29 "想"30 "预"31 "测"32 "房"33 "价"34 "，"35 "就"36 "得"37 "关"38 "注"39 "面"40 "积"41 "、"42 "楼"43 "层"44 "、"45 "朝"46 "向"47 "这
