+### Writing style
+
+Write like a developer explaining something to a colleague over lunch — clear, direct, slightly casual. The reader is a Chinese-speaking programmer, not a professor or a manager.
+
+**Core rules:**
+
+1. One sentence, one idea. If a sentence has "并且" or "同时" connecting two independent thoughts, split it.
+2. Prefer short sentences (under 30 characters) over long ones.
+3. Use spoken Chinese word order, not English-influenced structure.
+4. Technical terms can stay in English if they're more commonly used that way (e.g. API, JSON, decorator, endpoint).
+5. Don't hedge. If something is true, say it. Don't write "可能" or "或许" unless the original text genuinely expresses uncertainty.
+
+**Patterns to avoid (AI-style Chinese):**
+
+| ❌ Don't write | ✅ Write instead | Why |
+|---|---|---|
+| 将其复制到...文件中 | 复制到...里 | "将其" is literary, not spoken |
+| 该行显示了...的URL地址 | 这行告诉你...的地址 | "该" as a pronoun is stiff; "地址" already implies URL |
+| 你将会看到 | 你会看到 | "将会" is news-anchor tone |
+| 它并非...而只是... | 不是...就是... | "并非...而只是" is essay-style |
+| 可能像下面这样 | 长这样 / 像这样 | "可能" is unnecessary hedging |
+| 由于路径首先匹配，因此始终会使用第一个定义的 | 路径优先匹配，永远走第一个 | Remove "由于...因此" scaffolding |
+| 通过从 str 继承，API 文档就能... | 继承 str 后，API 文档会... | "通过从...继承" is English grammar mapped to Chinese |
+| 能充分利用它的功能和优点 | 功能强还好用 | Don't inflate simple ideas |
+| 在使用 GET 时，...的交互式文档不会显示... | GET 请求不显示... | Remove filler ("在使用...时") |
+| 这并非偶然，整个框架都是围绕这种设计构建的 | 这不是巧合，整个框架就是这么设计的 | "围绕...构建" is a translation of "built around" |
+| 导入 Enum 并创建继承自...的子类 | 导入 Enum，写个继承...的子类 | "并创建" is formal; "写个" is natural |
+| 在路径操作函数内部直接访问模型对象的所有属性 | 在路径操作函数里直接访问模型的所有属性 | "内部" → "里"; "对象的" is redundant |
+
+**More patterns to watch for:**
+
+- ❌ "你可以在...中找到..." → ✅ "在...里" or just state it directly
+- ❌ "值得注意的是" → ✅ "注意" or just make the point
+- ❌ "在这种情况下" → ✅ "这时" or "这种时候"
+- ❌ "从...的角度来看" → ✅ Remove; just state the fact
+- ❌ "对于...而言" → ✅ Remove; restructure the sentence
+- ❌ "关于...的问题" → ✅ Remove; just name the topic
+- ❌ Redundant "你的" (your) — English needs "your API", Chinese often drops it when context is clear
+
+**Reference style:**
+
+Think of how these write technical Chinese:
+- Vue.js Chinese docs (vuejs.org/zh) — clean, direct, developer-friendly
+- 阮一峰's blog — conversational but precise
+- Go by Example Chinese (gobyexample-cn.github.io) — minimal, no fluff
+
 ### Grammar and tone
 
-- Use clear, concise technical Chinese consistent with existing docs.
-- Address the reader naturally (commonly using “你/你的”).
+- Use "你" (not "您") to address the reader.
+- Keep the tone helpful but not condescending. Don't over-explain things that are obvious to a developer.
+- If the original English uses "you can..." or "you will see...", consider whether the Chinese version even needs the subject. Often you can drop "你" and just state the action.
