Let me check the debug logs and fix these issues:

I see the issues now:

1. The error is caused because bazi-chart.tsx still uses birthData.birthDate.split("-") but the form now sends separate fields birthYear, birthMonth, birthDay
2. The calendar toggle is still a Switch, should be two radio buttons for Lunar/Solar selection
3. Need to check the Tu Vi page as well

Let me fix these issues:

Now let me update the calendar toggle to use radio buttons instead of a switch:

Now let me remove the unused Switch import:

Now let me check the bazi page to ensure it's passing the correct data to the chart:

I see the issue - the bazi page still uses the old BirthData interface. Let me update it:

Now let me check the Tu Vi (ziwei) pages to ensure they also work:

I see the Tu Vi page also has the old interface. Let me update both:

Now let me update the Tu Vi page to actually show the chart when submitting the form:

I've fixed all three issues:

1. Calendar toggle: Changed from a Switch to two radio buttons (Lịch Dương / Lịch Âm) for clearer selection
2. BaZi error: Updated the BirthData interface to use separate birthYear, birthMonth, birthDay, birthHour fields instead of birthDate and birthTime strings, and fixed all related code that was calling .split() on undefined
3. Tu Vi page: Added the ZiWeiChart component import and now displays the actual Tử Vi chart when the form is submitted instead of showing a "generating" placeholder

The diagnostic output shows animation state changes from Framer Motion components - these are differences between animated values (width, height, position, backgroundColor) as particles animate over time. This is normal behavior for animated particle effects, not actual errors or crashes.

No fix is needed - the animations are working as intended.

Now I see the problem - the ZiWei chart is still using birthData.birthDate.split("-") and birthData.birthTime. Let me fix this:

I've fixed the ZiWei chart component by:

1. Added the HOUR_DISPLAY map for converting birth hour IDs to display names
2. Updated formatBirthDate() to use the new separate fields (birthYear, birthMonth, birthDay) instead of birthDate.split("-")
3. Added getBirthHourDisplay() function to display the birth hour properly
4. Updated all references in the center info section and header to use the new field structure

The diagnostic output shows animation state changes from Framer Motion components - these are differences between animated values (width, height, position, backgroundColor) as particles animate over time. This is normal behavior for animated particle effects, not actual errors or crashes.

No fix is needed - the animations are working as intended. The ZiWei chart error has been fixed and should now display correctly when you submit the form.
