Thank you very much for your contribution, your code translation would be greatly helpful for our Go Wechaty code base with a huge code line of improvement!

I'd like to invite @dingdayu to have a look at your PR and to see if he has any comments because we are just talking about the naming styles for the enums in Go (see #6)

And it's our great pleasure to have you onboard, welcome!
