Hello @poling chen ,
Thank you for posting here.
Based on my resear and test in my lab, that only the Appdata\Roaming folder is redirected. The Appdata\Local and Appdata\LocalLow folders are not redirected.
Here is the test result in my lab.
I configured the GPO setting User Configuration\Policies\Windwos Settings\Folder Redirection\AppData(Roaming) and applied it to one domain user (B\yu2).
Here are two similar cases for your reserence.

It seems we can not roaming the AppData\Local folder.
Hope the information above is helpful.
