+## 项目介绍 / Project Introduction
+
+基于大语言模型的文档理解与多源数据融合系统，专为第十七届中国大学生服务外包创新创业大赛（A23赛题）开发。本系统利用大语言模型（LLM）解析、分析各类文档格式并提取结构化数据，支持通过自然语言指令自动填写模板表格。
+
+A document understanding and multi-source data fusion system based on Large Language Models (LLM), developed for the 17th China University Student Service Outsourcing Innovation and Entrepreneurship Competition (Topic A23). This system uses LLMs to parse, analyze, and extract structured data from various document formats, supporting automatic template table filling through natural language instructions.

-- `extract_template_fields_from_docx(file_path)` - 从 Word 文档提取模板字段定义
-- `_infer_field_type_from_hint(hint)` - 从提示词推断字段类型
-
-**功能说明**:
-- 专门用于比赛场景：解析表格模板，识别需要填写的字段
-- 支持从表格第一列提取字段名，第二列提取提示词/描述
-- 自动推断字段类型（text/number/date）
-

-- 新增 `_build_context_text()` - 构建上下文（优先使用表格数据）
-- 完善 `_get_template_fields_from_docx()` - Word 模板字段提取
-
-**核心流程**:
-```
-1. 加载源文档（MongoDB 或文件）
-2. 对每个字段调用 LLM 提取值
-3. 返回填写结果
-```
-
-### 3. backend/app/api/endpoints/templates.py
