Hello I have added the file /chinese/security/2017/index.wml and the corresponding Makefile, and I will track the next builds to see if this one is also having the same problem as /index and /security/index, or if it's updated properly when a new security advisory is published.
If the www.debian.org/security/2017/index.zn-*.html pages are shown updated, we can take the Makefile as example to try to fix the other ones. If this page also suffers the bug, I think we can tinker more safely with its Makefile since less "important" pages are affected, and when we get the clue, go and fix the other ones, more complex. Chinese team: I think it's not relevant (for this bug) if this page is translated or not, but if you want to translate it, please go ahead :-) Cheers -- Laura Arjona Reina https://wiki.debian.org/LauraArjona
