Maybe this is inappropriately to send such an email to this mailing list,
but I can't find more appropriate mailing list (there are few Chinese people
in svnbook mailing list).
I have started to translation svnbook-1.8 for Chinese since May, 2017, and
currently working on chapter 7. I hope more people will join this translation
project. See http://svnbook.red-bean.com/index.zh.html for details.
