how to submit a patch about change in webpage

[mudongliang <mudongliangabcd@hotmail.com>]

I found some small spell error in the webpage : 
https://www.debian.org/doc/manuals/debian-faq/ch-ftparchives.zh-cn.html
It is written in Chinese! I want to change this html and make a patch!
Where should I post this patch to ?
And who should I contact to about this?
