[QUESTION] Where can I find the annotation scheme of XPOS for Chinese in stanza?

[eddieabc]

I'm using Stanza to do annotation works for my treebanks. I find that I need a annotation guide table to help me recognize the specific meaning for each XPOS tag for Chinese words. However, I cannot find any relevant guide for XPOS tags.

It is trained from this treebank:

https://github.com/UniversalDependencies/UD_Chinese-GSDSimp

which I believe was converted from this traditional character treebank:

https://github.com/UniversalDependencies/UD_Chinese-GSD

But unfortunately I'm not seeing a lot of documentation on the xpos at either repo. You can possibly ask your questions there
