I made the tiny change to guix-artwork’s ietf-tags.scm as
04c96a370b8cae48ed162e4414b8950cc65c513b now (sorry for taking so
long):

Note that the prior zh-cn URLs will be broken.

I will play around with nginx’ map directive to make zh-cn and zh
Accept-Language settings direct to the proper URL later, afterwards I
will close this bug.  zh-cn URLs remain invalid.  Links to the manual
continue to use zh-cn.

For testing I dug out the VM code
<https://lists.gnu.org/archive/html/bug-guix/2020-04/msg00195.html>
where I had removed parts of berlin that are not relevant to the
website.  The change breaks neither website nor manual.

Thanks ylc991 for the report!
