Hi ZoEy Xu,
I don't have a great explanation for why this works, but you can get all of the paths drawing by changing the Country detail to Min(Country). I drew inspiration from an older forum post (Paths on map using generated Lon/Lat ) to make the attached workbook showing the result. It seems to me that this is making all of the right paths draw.

Aha! I just found out that literally this morning! Thank you for your answer. You just give me more confident to doing so. I don't know why that work neither but it does the job.
Thank you so much!

I think I have the answer for why this worked... I talked with Dan Cory about this and here is what he had to say:
"Tableau breaks the paths by the dimensions. You have “PathID-Zip” as a dimension, so the path breaks for every PathID-Zip.
So if Country is a dimension as well, it breaks on countries. Change it to an attribute and it no longer breaks on countries.
You should be able to change it to ATTR instead of MIN or MAX, but attributes were added later and that was never fixed."
I found this useful to understand the problem...I hope it helps you as well.
YES!!! That actually help a lot. I could image how the path map works now. Thanks for your information.
