+### 4. **CRITICAL: Code Block Translation Rules**
+- **ONLY translate SQL comments that start with `--`**
+- **For ASCII tables/diagrams with text content:**
+  - You MAY translate the text content IF you can maintain exact alignment
+  - **Apply technical term format: 中文翻译（英文名词）** for relevant terms
+  - **MUST preserve all spacing, padding, and visual structure**
+  - **Count character widths carefully** (Chinese characters = 2 width, English = 1 width)
+  - **Add/remove spaces as needed to maintain column alignment**
+  - **If alignment cannot be maintained perfectly, DO NOT TRANSLATE**
+- **NEVER translate:**
+  - Pure ASCII art symbols (┌─┐│└┘├┤┬┴┼)
+  - Code syntax, commands, outputs
+  - Variable names, function names
+- **When in doubt about alignment, DO NOT TRANSLATE**
 
 ### 5. Process LANG_REPLACE Comments
 - Replace with Chinese version specified after `cn=`
