zh-CN: Translate Concurrency morning

[mgeisler]

Hi all,

This translation was prepared by our in-house localization team. Since I don't speak Chinese, please look it over and add suggestions. I've already spotted a few problems with the Markdown.

Let me know how the translation itself looks — if it looks good, I can send them bigger parts to translate!

Thanks for your help! Part of #324.

Thanks for getting the localization team on this translation! I think the translation is great in general. Left some minor nits.

Awesome, that's great to hear! I think the translator has limited context and they'll not be aware of anything discussed on #324 or in the other PRs.

Thanks for leaving suggestions! I have no way of checking them so you should either commit them yourself or I'll blindly accept them later 😄

That applies to all reviewers: please use the GitHub suggestions in your comments. Feel free to commit the suggestion directly unless you feel another reviewer should look at it too.

Thanks @anlunx and @xusiwei for reading the translation! Let me know when you think we can merge this.
