@TangoEnSkai Do you have any plan to update those? I want to contribute to the golang translation.

@Yupjun sorry for my late reply. I had a very long vacation.

Sure, you can create a PR for these.

I am actually thinking about restarting this issue in this month. Let me know if you want to contribute, and which part you want to do.

**also, let me update this issue with the latest release since the target content [2020/04/19](https://github.com/uber-go/guide/blob/master/CHANGELOG.md#2021-04-19) seems out of date.

We can aim for the latest version: https://github.com/uber-go/guide/blob/master/CHANGELOG.md#2022-03-30
