## What it is
An open-source Zi Wei Dou Shu (Purple Star Astrology) chart calculation engine based on Ni Haixia's Tianji system, written in TypeScript with a Next.js frontend. It includes complete charting algorithms, the Si Hua flying-star system, a pattern knowledge base, classical text data, and a 518,400-sample chart dataset for AI fine-tuning and RAG.

## Use cases
- generate a zi wei dou shu natal chart from a birth date and time
- fine-tune a small language model on fortune-telling input-output pairs
- build a RAG retrieval source for Chinese astrology chatbots
- compare chart pattern rules after modifying the patterns knowledge base
- research purple star astrology chart combinations statistically
- read and search classical zi wei dou shu texts
- compare two people's charts for relationship analysis

## When to choose
- you need a programmatic Zi Wei Dou Shu charting engine with a permissive MIT license
- you want a large labeled chart dataset for LLM fine-tuning or RAG
- you want to build a Chinese astrology web app on Next.js

## When to avoid
- you need Western astrology or BaZi-only charting
- you need the hosted AI interpretation prompts, backend APIs, or user/payment systems, which are not open-sourced
- you need a non-TypeScript/JavaScript implementation
