Someone leaked internal Chinese government documents on GitHub (opens in new tab)

For us non-Chinese speakers, some sort of background or description as to what these files are would be greatly appreciated.

Here's a security researcher's "unrolled" tweet thread of interesting findings contained in the leak: https://threadreaderapp.com/thread/1759326049262019025.html

I have no idea what is this, but the issues section is kinda funny.
