A public copy is available at
https://openstd.samr.gov.cn/bzgk/gb/newGbInfo?hcno=69E793FE1769D120C82F78447802E14F,
pressing the blue "online preview" button, enter a captcha and you can
see it.  But the copy is in Chinese, and there's an explicit notice
saying translating this copy is forbidden, so I cannot translate it for
you either.

I'm not an lawyer but I guess contributing code for that may have some
"cryptography code export rule compliance" issue.
