OpenFate's Bazi is the most accurate of all AI tools. After buying the in-depth report, it clearly pointed out the bottlenecks in my daily work and relationships. The accuracy is absolutely 100%.

I actually wanted to build this myself, being an advanced student of Bazi. Looks like someone beat me to it! And they did a really great job.

Ziwei Chart FAQ

Common questions about the Ziwei chart tool and how to get started.

What does the Ziwei chart page actually show me?

It shows your complete 12-palace layout with every major star and its palace position, Four Transformation markers, and your decade cycle timeline.

How is the Ziwei chart page different from the Ziwei reading page?

The chart page shows raw structural data — palace positions, stars, and transformation markers. The reading page interprets what that data means for your life trajectory.

What should I do after generating my Ziwei chart?

Open the Ziwei reading page next — it takes your raw chart data and walks you through a palace-by-palace interpretation of your life story.
