Thank you @remeio ,

But these links are for people who cannot read Korean.

https://mybatis.org/mybatis-3/zh/
So, it's not appropriate to translate.

Hi @remeio ,

My comment does not match the change in this PR, so I must have misunderstood something.
Could you submit a new PR? (as the branch is deleted, we cannot reopen this one)

Hi. I had restored this branch fix_doc_language_of_ko.

Hi, I will commit a new PR to resolve conflict. Wait a moment.

@remeio ,

Sorry, the target file has been migrated to Markdown format a while ago.
https://github.com/mybatis/mybatis-3/blob/729aed778b017f546e425c4193d2669efe897a58/src/site/ko/markdown/index.md

Can you make the same change to that file instead?
