 **Critical Rules (Must Follow):**
 
-1. **You must set `template_path`** to `csv-data-analysis/templates/report_template.html`. The template has built-in complete ECharts rendering JavaScript code and all section titles and footer text. You only need to fill in 8 content placeholders via the `data` parameter. **Never write or modify any JavaScript chart rendering code yourself.**
+1. **You must set `template_path`** to `csv-data-analysis/templates/report_template.html`. The template has built-in complete ECharts rendering JavaScript code and all section titles and footer text. You only need to fill in 9 content placeholders via the `data` parameter. **Never write or modify any JavaScript chart rendering code yourself.**
 
 2. **Marker data blocks are automatically injected by the backend** — you must not pass them in `data`. The backend automatically extracts content from `###KEY_START###...###KEY_END###` markers in the script output and injects it into the template; in this skill, this is primarily `CHART_DATA_JSON`.
 
 3. **`*_INSIGHTS`, `EXEC_SUMMARY`, and `CONCLUSIONS`** must use HTML formatting (e.g., `<p>`, `<ul>`, `<li>`, `<strong>`, `<ol>`) to ensure proper layout. These are deep business insights you write based on the statistical summary.
 
-4. **The output language must match the user's input language.**
+4. **The output language must match the user's input language.** You must also pass the `LANG` placeholder (`"en"` or `"zh"`) so that the template's hardcoded section titles, labels, and footer text are displayed in the matching language. Detect language from the user's query: if the user writes in English, set `LANG` to `"en"`; if the user writes in Chinese, set `LANG` to `"zh"`. Default to `"zh"` when uncertain.
 
-5. **Pass exactly 8 placeholders — no more, no less.** Auto-injected marker fields like `CHART_DATA_JSON` are handled by the backend and should not be passed by you. The template already hardcodes all section titles (Distribution Analysis, Correlation Analysis, etc.), insight box titles ("Insights"), and footer text — you do not need to pass these.

 6. **Insight content must be substantive.** Each insight module should cover 4 layers of information: `observation`, `possible causes`, `business impact`, and `action recommendations`. Do not merely restate statistical values or write only a few vague conclusions.
