观易堂

观易堂 is an online platform for traditional Chinese metaphysics that brings together free tools for BaZi, Zi Wei Dou Shu, Qi Men Dun Jia, Liu Yao, and Mei Hua Yi Shu. Instead of piecing together scattered resources, you can generate accurate charts for all these systems in one place, at no cost.

Every chart is produced by a deterministic calculation engine that follows traditional calendrical and divination rules, so the underlying facts stay consistent and reliable. On top of those calculated facts, AI delivers structured interpretations, which means the readings are grounded in the chart itself rather than vague guesswork.

The BaZi reports go deep into the areas people care about most: life patterns, career, wealth, relationships, health, and current timing. Each section comes with clear explanations, relevant time references, and practical suggestions you can actually act on.

Beyond the charts, 观易堂 also offers a Xuanxue knowledge encyclopedia for anyone who wants to understand the principles behind the practice. If you need more than the free tier, paid membership plans unlock unlimited analysis and follow-up questions, so you can keep exploring any chart in depth.
