# 01 - Foundational Concepts (基础理论)

This directory contains the core theoretical foundations of the "Hu-Han Three Thousand Years" project.

## Core Documents

### 1. Phonetic-Semantic Framework
- **File**: `phonetic_semantic_framework.md`
- **Content**: The "音韵表意文字系统" (Phonetic Ideographic Writing System) theory
- **Key Concept**: "急促音 + 缓坡音" (abrupt sound + gentle slope sound) pattern

### 2. Heaven-Earth Logic Framework
- **File**: `heaven_earth_logic_framework.md`
- **Content**: The "天地相通" (Heaven-Earth Interconnection) philosophical framework
- **Key Concept**: Unity and dynamic interaction between heaven and earth in space, time, and social structures

### 3. Kulue Root Network
- **File**: `kulue_root_network.md`
- **Content**: The "圐圙" (kulue) root network and 32 core vocabulary words
- **Key Concept**: Semantic network demonstrating phonetic-semantic cultural logic

### 4. Core Definitions (Programmatic)
- **File**: `core_definitions.py`
- **Content**: Python implementation of core theoretical concepts
- **Purpose**: Programmatic repository for systematic analysis and validation

## Theoretical Foundation

These documents form the **linguistic and philosophical foundation** for the entire project. They establish:

1. **Methodology**: Phonetic semantic network analysis
2. **Philosophy**: Heaven-earth interconnection as cultural super-meaning
3. **Evidence**: 32-word semantic network centered on "圐圙"
4. **Validation**: Multiple verification across linguistics, history, geography, and culture

## Reading Order

For new readers:
1. Start with `phonetic_semantic_framework.md` to understand the methodology
2. Read `heaven_earth_logic_framework.md` for the philosophical core
3. Explore `kulue_root_network.md` for empirical evidence
4. Reference `core_definitions.py` for systematic definitions
