Before starting to translate Wiki in local languages, we need to consolidate english version, as we made with Deepin OS translation!

In my opinion, this will slow down the whole thing a little bit. You're right the English texts i saw at the wiki have grammar issues for example, by now. But honestly there is no sense in waiting for the translation team to correct errors they may never have seen or noticed by their self's before.

Other languages will have other grammar rules and I do not see a problem with starting translation as early as possible. Revision is an ongoing process for all kinds of content so what exactly is the problem here?

Do you mean you have to test the content of the wiki like you test an issue un a closed beta test? Is there a sirrius reason to slow down progress intentionally.

No no, I just said that Deepin team is building the Wiki day by day, there are so many items missing.
If they will move or erase somthing in the original version we have no control on it for translated one. (example, today there is a topic called "Network applications" and tomorriw it will be erased, so we have to re-translate it..).
I mean, they are chinese people and they open their eyes to english speaking people (I'm italian, you're german, english is common here, not in china) and what they asked is to improve english/chinese wiki, translations are not a priority of today, but just in future..

This is just my point of view, based on my experience because I've translated Deepin to Italian (4K strings, not easy..).

I See thank you for you expertise!
