What is Life K-Line?
Life K-Line (人生K线) is a self-hosted web application that visualizes personal destiny using traditional Chinese BaZi (Eight Characters) astrology combined with AI large language models. It renders life fortune trajectories as interactive K-line charts similar to stock market visualizations, covering ages 1-100 with major and annual luck cycles. The application provides intelligent BaZi chart calculation with true solar time correction, AI-powered deep analysis covering personality, career, wealth, relationships, health, and even Web3/crypto trading fortune. It includes a celebrity case library for comparison learning and a knowledge hub for astrology education. The stack uses React 19, Vite, Express.js, SQLite (better-sqlite3), Recharts for charts, and lunar-javascript for precise calendar calculations. It supports any OpenAI-compatible API including local models via Ollama or LM Studio. Self-hosting requires Node.js 18+ and an AI API key; the backend runs on port 3000 and frontend on 5173. Licensed under Apache 2.0.

FAQ
人生K线测算页是什么？
Life K-Line outputs structured BaZi charts and phase rhythms based on birth time and location: first determines day master and favorable elements, then major/annual luck windows, finally actionable steps for career, wealth, relationships. Suitable for 'judge first then act' decisions, not daily fortune fear-mongering.
如何使用
Fill in birth date, time and location; read the structural axis of day master and favorable elements with current major luck; then choose tools or ask follow-up questions for career/wealth/relationship intent with verifiable checkpoints.
报告是否公开？
Reports can share summary pages; high-quality anonymous cases may enter public content stream after desensitization, private reports can disable public access.
需要准确到时辰吗？
More accurate birth time gives more stable day pillar and favorable elements. Uncertain times can start with rough calculation and note the time precision in the report.
人生K线和普通算命有什么区别？
Life K-Line emphasizes structure, phases, and actionable boundaries, outputting verifiable rhythm judgments rather than replacing real choices or using fear-based fortune-telling.
