Someone leaked internal Chinese government documents on GitHub

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

Here&#x27;s a security researcher&#x27;s &quot;unrolled&quot; tweet thread of interesting findings contained in the leak: <a href="https:&#x2F;&#x2F;threadreaderapp.com&#x2F;thread&#x2F;1759326049262019025.html" rel="nofollow">https:&#x2F;&#x2F;threadreaderapp.com&#x2F;thread&#x2F;1759326049262019025.html</a>

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