new mirror on mirrors.tuna.tsinghua.edu.cn
Thanks to @z4yx we now have a new mirror in China! Anyone can add it by clicking on this link:
Its also available via rsync:
rsync -axv mirrors.tuna.tsinghua.edu.cn::fdroid/ /path/to/fdroid/
Its on the mirror monitor mirror-monitor!9 (merged) Once the whole setup proves stable, we can add it as an official mirror.
