The user wants a 1500+ word article (must be at least 1500, cannot be less than 1050). They want 6-8 natural paragraphs, each 150-250 words. So total must be roughly 1500 words. 6 paragraphs of 250 words each = 1500, 8 paragraphs of 200 each = 1600. So we need to produce 6-8 paragraphs, each 150-250 words, total at least 1500, likely around 1600-1800 words. Must be natural, conversational, no AI phrases, no numbered lists, bullet points, etc. Must not use prohibited words. Must not use intro phrases like "". Must not use transition words like "、". Must not use "让我们...", "。比如，业务系统使用mysql，日志系统用mongodb，报表部分依赖postgres。若只能依赖单一数据库，势必会导致代码割裂，维护成本上升。这时候，laravel 多数据库配置就成了提升效率的关键点。通过合理的配置，能够在同一个框架里同时管理多个数据源，让业务逻辑更加清晰，也让团队协作更加顺畅。接下来，我们就来聊聊如何在laravel中实现多库管理，以及它带来的种种便利。"
Count words? Let's count roughly:
"In" not needed English but Chinese words count? We count Chinese words? Usually word count is based on Chinese characters separated by spaces? But they likely count tokens. We'll approximate length. Let's count Chinese words manually? Hard. But we can approximate length. It's okay as long as roughly 150-250 words. Let's count Chinese words separated by spaces? Actually they didn't specify token counting; they just want 1500+ characters? They said "字数要求：必须写满1500字，不能少于1050字！" That's Chinese characters count. So we need Chinese characters count >=1500. So we need to produce at least 1500 Chinese characters. That's easier. So we need at least 1500 Chinese characters. We can produce about 6 paragraphs each ~250 characters, total ~1500 characters. That's fine.
Thus we need to ensure Chinese characters count >=1500. Let's produce about 1600 characters.
We need to avoid prohibited words (in Chinese). They listed Chinese prohibited words: "踩坑、引入、背景、发展、充分、浅析、高度、解决、方法、模型、这段文字、阐述、重要、强调、核心要点、核心观点、核心内容、核心点、关键词、二、三、四、五" etc. We must avoid those. Also avoid English words? They listed some English phrases to avoid: "、". We can avoid them.
We can use Chinese words like "开发", "项目", "需求". That's fine.
We must avoid "踩坑". Good.
We must avoid "引入". Avoid "背景". Avoid "发展". Avoid "充分". Avoid "浅析". Avoid "高度". Avoid "解决". Avoid "方法". Avoid "模型". Avoid "这段文字". Avoid "阐述". Avoid "重要". Avoid "强调". Avoid "核心要点". Avoid "核心观点". Avoid "核心内容". Avoid "核心点". Avoid "关键词". Avoid "二、三、四、五". Avoid "、". Also avoid "让我们...". Avoid "。比如，主业务使用传统的mysql，日志系统采用mongodb，统计分析依赖redis。单一数据库的写法在面对这些场景时显得力不从心，代码会显得杂乱，维护成本也随之上升。于是，laravel 多数据库配置就成了提升开发效率的关键手段。通过在同一个框架里同时管理多个数据源，能够让不同业务模块各自独立，同时又保持代码统一，团队协作更加顺畅。下面，我们就来深入探讨如何在laravel中实现多库管理，以及它带来的种种便利。"
Count characters? Roughly maybe 250. Let's approximate.
Paragraph 2 (250 characters):
"多库配置的核心在于把不同的数据连接放在同一个配置文件里。laravel 的 config/database.php 里提供了 connections 数组，开发者只需要为每个数据库添加一个独立的连接配置，包括驱动、主机、端口、数据库名称、
