## What is Yi Jing Pro?

Welcome to the Yixue Compendium, a comprehensive application that integrates traditional Chinese culture with modern technology. Our goal is to provide users with convenient and accurate divination services while helping them better understand and learn about the I Ching and its related knowledge. Here is a detailed introduction to the features of the Yixue Compendium:

Divination and Interpretation

Dayan Divination Method: The Dayan Divination Method is a form of divination described in the I Ching. It involves using fifty yarrow stalks (actually using forty-nine) in a complex process to derive a hexagram. Our app faithfully recreates this process, allowing users to experience this ancient method firsthand.
Three Talents Divination Method: The Three Talents Divination Method is one of the commonly used ancient divination methods. By analyzing hexagrams through the three talents of heaven, earth, and humanity, it provides detailed interpretation results to help users understand the meanings behind the hexagrams.
AI Interpretation: By integrating modern artificial intelligence technology, the AI assistant can quickly and accurately interpret hexagrams. Users only need to input the divination results, and the AI assistant will provide detailed analysis based on I Ching theory, making it easy for users to understand and apply.
AI Assistant

Intelligent Q&A: The AI assistant can answer user questions about the I Ching, Feng Shui, the Chinese calendar, and more, providing instant consultation services.
Learning Guidance: Based on the user's learning progress, the AI assistant provides personalized learning suggestions and resource recommendations to help users systematically study the I Ching and its related knowledge.
Interactive Answers: Users can interact with the AI assistant through Q&A to deepen their understanding of the I Ching and hexagrams.
Calendar

Perpetual Calendar: Provides a detailed calendar function, including Gregorian and lunar dates, for users to view at any time.
Solar Terms and Festivals: Lists the solar terms and traditional festivals of each year in detail and provides related cultural knowledge to help users better understand the origins and customs of traditional Chinese festivals.
