The user wants me to revise the previous draft to have 500-800 Chinese characters. The previous draft was 565 characters, which is below the 500 minimum. Wait, 565 is above 500. Let me re-read: "少了就补学习顺序、门槛、学完产出、资料用法;多了就删重复和空话,不要超过 800。" The previous draft was 565, which is > 500, so it should be fine on the lower bound, but the user says it's "不合格" (unqualified). Maybe the character counting is strict or there's an issue with the content. Actually, the user says "上一稿有 565 个汉字,不合格" - so even though 565 > 500, it's considered unqualified. Perhaps the issue is that the content doesn't fully meet the requirements, or the character count method is different. Let me just expand the content to be more comprehensive and ensure it hits 500-800 characters properly, adding more substance about learning order, prerequisites, post-learning capabilities, and material usage. Let me rewrite with more depth while keeping it focused on the Tomcat/Java Web topic. Let me draft a new version: ```html
``` Let me count the Chinese characters in this draft. I'll count carefully. Actually, let me count more carefully. The user said the previous draft had 565 characters and was "不合格". Maybe the issue is that the content wasn't structured well enough or didn't fully address all requirements. Let me make sure I cover:
1. What problem does this course solve ✓
2. What's the prerequisite foundation ✓
3. Which modules to watch first ✓
4. What can be done independently after learning ✓
5. How materials support practice ✓ Let me count the Chinese characters (excluding punctuation and English) in my draft: 第一段: 这门课解决什么问题 很多 Java Web 开发者掌握了 Servlet 和 JSP 代码却不知道 Tomcat 内部如何接收请求如何加载类如何输出响应当项目部署到服务器遇到启动失败或端口占用时往往缺乏排查手段这门课聚焦 Tomcat 容器底层运行机制解决从代码编写到工程部署落地时的工程痛点帮你把黑盒运行环境变成可理解的工程体系 Let me count: 这门课解决什么问题(8) 很多(2) Java(1) Web(1) 开发者掌握了(6) Servlet(1) 和(1) JSP(1) 代码却不知道(7) Tomcat(1) 内部如何接收请求(8) 如何加载类(5) 如何输出响应(6) 当项目部署到服务器遇到启动失败或端口占用时往往缺乏排查手段(27) 这门课聚焦(5) Tomcat(1) 容器底层运行机制(8) 解决从代码编写到工程部署落地时的工程痛点(19) 帮你把(3) 黑盒运行环境变成可理解的工程体系(16) = 8+2+1+1+6+1+1+1+7+1+8+5+6+27+5+1+8+19+3+16 = 127 This is getting tedious. Let me just write a good draft and estimate the character count. I'll aim for around 650-750
