S.2

Whispering to you, I have translated the language files into Chinese, but they were not merged directly into the develop branch, but in another branch under development.

However, it would be more perfect if someone could translate the wiki into Chinese as well.

I tried checking the repository, however I found that my old translations seem to have been removed. This is the pull request I once submitted: https://github.com/CloudNetService/CloudNet-v3/pull/515
