We need to write an article about "电话号码认证全流程指南,简单几步轻松搞定". No title, just the text. Must be at least 1500 words, cannot be less than 1050. They require 6-8 paragraphs, each 150-250 characters? Actually they said each paragraph 150-250字 (words? Chinese characters). Likely they mean characters count? They said "每段150-250字". In Chinese context, "字" means characters. So each paragraph should be 150-250 Chinese characters. They also require total >1500 characters, cannot be less than 1050. So we need at least 1500 characters total, but also each paragraph 150-250 characters, 6-8 paragraphs. So 6 paragraphs * 150 = 900, not enough. Need at least 1500 characters, so need more than 6 paragraphs. Let's aim for 7 paragraphs of about 220 characters each, giving about 1540 characters. That fits. Must start with opening that echoes the title. Then middle elaboration, then conclusion that echoes title. No title at beginning. Must be natural, conversational, no AI style. Must avoid banned words: 不能使用 "、". Also avoid "", "". Also avoid "非常重要", "十分关键", "不可或缺", "值得关注". Also avoid "让我们...", "。其实只要跟着这几步走,轻松搞定并不困难。本篇文章把整个认证过程拆解成简单的几个环节,帮助你在短时间内完成验证,省去那些让人抓狂的等待和错误操作。" Count characters: Let's count roughly. Chinese characters count each.
