@zhang2014 could you pull request this on top of https://github.com/yandex/ClickHouse/blob/master/docs/zh/index.md ? (remove the symlink and replace it with translation)

[sundy-li]

Note that Chinese has full-width punctuation, en version -> , . : ( ) , zh version -> ，。 ：（ ）

[zhang2014]

Ok, I'm glad to help you : )
but how about the review of Chinese documents ?

[sundy-li]

@blinkov
How about make @zhang2014 and me as Chinese doc reviewers ? Every Chinese doc translate pull request to ClickHouse, just assign the pr to one of us (could be more member in the future), and we will review the doc and decide if it could be merged.

@zhang2014 @sundy-li 👍

[blinkov]

@sundy-li I'm not sure how many people will join to contribute to zh docs in official repo, but help with reviewing is also definitely appreciated. I'll try explicitly cc you in any relevant PR I see, thanks.
