Recommend a project for beginner

I am a Golang developer from China, I wrote a simple database project using Golang while I am learning last year, it helps me a lot.

Here is the project :

So I want to recommand this project to you, and I wish it help you learn more about Golang. As I am also a beginner, so the project maybe imperfect, so i hope you can give me some issues or PRs.

Thanks for your kind!
