We need to write article 1500+ characters (words? The prompt says "字数要求:必须写满1500字,不能少于1050字!" It says "字数要求:必须写满1500字,不能少于1050字!". Usually Chinese characters count. They want at least 1500 Chinese characters, not words. They also say each paragraph 150-250 characters? They said "每段150-250字". That likely means characters, not words. So we need 6-8 paragraphs, each 150-250 characters, total at least 1500 characters. So 6 paragraphs 150 = 900 characters, too low. Must be 1500 characters total. If each paragraph 150-250 characters, 6-8 paragraphs => total 1500-2000 characters. So we need roughly 7 paragraphs of ~215 characters each gives ~1505 characters. Let's aim for 7 paragraphs, each about 220 characters. Ensure total >=1500 characters. No title. Must start with opening that echoes title: "手机一响就心惊,快学这招标记骚扰号码". So first paragraph should reflect that.

We must avoid AI style words, must be natural, no banned connectors. Use short sentences, active voice, concrete examples. Must not use those banned words.
We need to talk about "标记骚扰号码" (labeling spam numbers). Provide steps, why important, benefits, examples, maybe mention built-in features of Android/iOS, third-party apps, caution about privacy, etc. Must end with conclusion that circles back to title.
We need to ensure each paragraph 150-250 characters. Let's count roughly. We'll write paragraphs of about 220 characters each. Need 7 paragraphs => 1540 characters approx. Let's craft.
We must not use the banned transition words: "、". Also avoid "开头禁用" etc. So just write paragraphs with natural flow.
We must not use "让我们...、。陌生号码跳出来,心里总有一种不安。其实大多数骚扰电话都有规律,只要学会把它们标记出来,麻烦就会大幅降低。"
Count characters: Let's count manually.
手机一响就心惊,这种感觉谁都会遇到。陌生号码跳出来,心里总有一种不安。其实大多数骚扰电话都有规律,只要学会把它们标记出来,麻烦就会大幅降低。
手(1)机2一3响4就5心6惊7,8这9种10感11觉12谁13都14会15遇16到17。18陌19生20号21码22跳22? Wait need careful counting. Better approximate length; we need around 210 characters. Let's maybe write longer.
I'll write each paragraph more fully to reach ~210 characters. Let's count after writing.
I'll produce paragraphs then manually approximate length.
Paragraph1 (approx 210 characters):
"手机一响就心惊,这种突兀的铃声会让任何人瞬间紧张。尤其是陌生号码频繁出现,心里总会有一种莫名的不安。其实骚扰电话往往遵循一定规律,只要掌握标记方法,麻烦自然能被大幅削减。"
Now count characters (including punctuation?). Let's count roughly:
手1机2一3响4就5心6惊7,8这9种10突10? Actually "突" is 9? Let's count properly maybe easier to approximate length ~180? Might be okay as long as total reaches 1500 across 7 paragraphs. We need each 150-250 characters, so 180 is okay.
But we need to ensure overall total >=1500 characters. If each paragraph ~180, 7180=1260, not enough. So need each around 215. Let's aim for ~220 characters each.
I'll write paragraphs with about 220 characters.
I'll write them and then count roughly.
"手机一响就心惊,那一瞬间的紧张感会让人本能地皱眉。尤其是陌生号码频繁弹出,总有一种莫名的不安蔓延。其实这类骚扰电话往往遵循固定模式,只要学会把它们标记出来,麻烦的出现频率就会大幅下降。"
Now count characters (including punctuation). Let's count quickly: I'll count characters ignoring punctuation? But need approximate. Let's count manually:

That's 83 characters? Actually I counted up to 83 characters? Wait I counted up to "降". Let's recount: I think I missed many characters after "降". The sentence ends with "降". Actually I wrote "降". So total characters maybe around 83? That's too low. My counting is off because I omitted many characters after "降". Actually the sentence continues? It ends with "降". So maybe my paragraph is too short. Let's rewrite longer.
We need each paragraph 150-250 characters. So we need to write longer sentences.
Better approach: Write paragraphs of about 200-250 characters, then we can be confident.
I'll write each paragraph with about 230 characters. Then ensure total >=1500.
Let's craft paragraphs more systematically, then count approximate characters.
Paragraph1 (target ~230 characters):
"手机一响就心惊,那一瞬间的紧张感会让人本能地皱眉。尤其是陌生号码频繁弹出,总有一种莫名的不安蔓延。其实这类骚扰电话往往遵循固定模式,只要掌握标记方法,麻烦的出现频率就会大幅下降。"
Now count characters roughly: Let's count again more carefully.
手1机2一3响4就5心6惊7,8那9一10瞬11间12的13紧14张15感16会17让18人19本20能21地22皱23眉24。25尤26其27是28陌29生30号31码32频33繁34弹35出36,总37有38一39种40莫41名42的43不44安45蔓46延47。48其实49这50类51骚52扰53电54话55往56往57遵58循59固60定61模62式63,只要64掌65握66标67记68方69法70,麻71烦72的73出74现75频率76就77大78幅79下80降81。
That's 81 characters? Something wrong: I'm counting each Chinese character as one, but I'm missing many characters because I omitted many after "降". Actually the sentence ends with "降". So maybe I counted correctly? That would be only 81 characters, far below target. That suggests my counting is off because I'm not counting punctuation? But still 81 characters is too low; a paragraph of 81 characters would be too short. So my text is too short. I need to expand to ~200 characters.
Thus I need to write longer paragraphs with more content.
